Suszarka do włosów Fema RSW-1 (1965)

W tym odcinku obejrzymy konstrukcję jednego z pierwszych masowo produkowanych modeli polskiej suszarki do włosów Fema RSW-1 z 1965 roku. Urządzenie powstało w ówczesnych Zakładach Wyrobów Elektrotechnicznych (później Zakłady Radiowe) Eltra w Bydgoszczy, jeszcze przed przeniesieniem produkcji suszarek do Farelu w Kętrzynie, funkcjonującego wtedy jeszcze pod nazwą Kętrzyńska Fabryka Sprzętu Elektrotechnicznego. Fema nie była wprawdzie pierwszą produkowaną w Polsce po II wojnie suszarką – oglądaliśmy w jednym z poprzednich nagrań powstało około 1953 roku suszarkę z Fabryki Rowerów i Wózków Dziecinnych w Rzeszowie (później Zelmer). Ale to właśnie Fema stała się prędko nieodłącznym elementem wyposażenia tysięcy polskich gospodarstw domowych przełomu lat 60-tych i 70-tych, a także zapoczątkowała całą serię późniejszych urządzeń. Suszarka zwraca uwagę nie tylko przemyślaną konstrukcją, ale też ciekawym wzornictwem. Prezentowany to egzemplarz suszarki RSW-1 wyposażony jest w silnik SAZ-2 z zakładów Tonsil we Wrześni. Obejrzymy działanie suszarki bez pokrywy. Poczytamy o jej właściwościach i możliwych naprawach, a także rzucimy okiem na schematy techniczne zawarte w książce „Elektryczne urządzenie domowe” z 1972 roku. Sprawdzimy też działanie automatycznego wyłącznika, chroniącego suszarkę przed przegrzaniem.

Pasjonatom historii, konstrukcji i designu zabytkowych suszarek zwracam uwagę na bardzo cenną i ciekawą wystawę, która od połowy marca 2024 r. prezentowana będzie w Olsztynie – dokładne informacje zamieszczę tutaj niebawem.

Fortunately, there is no risk of losing the warranty. And I think that now I will be able to open the casing. And now I can take the engine out, and then I’ll put this whole clip back in here. Here we are clearly dealing with Polish production,

With the SAZ-2 engine from Tonsil near Poznań. Yes, and as you can see, the dryer starts working immediately. I won’t bother it any longer in this open state, so as not to burn out all the elements of the heating coil.

This will now be disconnected and after closing the dryer we will check the operation of this safety feature. We’ll see it in a moment, let’s first turn on the power and cool air. Oh, and the dryer starts blowing warm air very nicely now.

Hi, I have some hair dryers on the table today. I’ll tell you about them in a moment. But I would like to pay special attention in today’s rather short recording to this old, one could say “iconic” Polish Fema hair dryer, manufactured at that time by, I think, called

Zakłady Wyrobów Elektrotechnicznych Eltra in Bydgoszcz, in 1965, as I see here on the nameplate. If I remember correctly, the Bydgoszcz plant had been operating under this name since the late 1950s, probably since 1957 and more or less until 1966,

Then they probably changed their name to Zakłady Radiowe Eltra and this is not without significance when it comes to hair dryers , but maybe we’ll talk about this story either at the end of this or in another recording. And I was inspired, motivated and encouraged to talk about this dryer

By yesterday’s very nice visit to Olsztyn, where – and this may interest you – a very interesting exhibition is being prepared about the history of Polish and not only Polish hair dryers. Let me not reveal yet who is organizing such an exhibition

And where it will be presented. I admit that I wouldn’t want to step out of line and do it in front of the organizers. I can only tell you that if you have time, if you live in Olsztyn or somewhere nearby, or if you have time for a pre-season trip to Olsztyn,

You will be able to visit this exhibition in Olsztyn from about mid-March. And if, or whenever, information and an invitation to participate in the opening ceremony of this exhibition or to visit the exhibition in the following days appear on the official website of the organizers,

I will include such information in the description of this recording, in a comment, and I will definitely devote at least one more recording to it. So I thought that it would be worth taking out my hair dryers and perhaps during the Olsztyn exhibition I should make one, two or three more recordings

Related to these hair dryers. So that these recordings could be a small supplement or reference to the Olsztyn exhibition. I admit that my collection of hair dryers is quite modest. Yesterday, during my visit to Olsztyn, I had the opportunity to see a truly impressive collection

Of Polish and not only Polish dryers, but there were a lot of these old, first models of Fema dryers, such as here this RSW-1 model from 1965, the SR-2 model produced in Bydgoszcz and the SR-2 model already produced in the Kętrzyn plant, or at that time it was probably called

Kętrzyńska Fabryka Sprzętu Elektrotechnicznego. It is no wonder that Olsztyn is particularly interested in these products, because after all, Kętrzyn and the history of the Kętrzyn factory are also the history of the region. Here I also have a much newer SR-3 dryer from Kętrzyn, and here I also have a foldable

Travel dryer SRp-2, also from the Kętrzyn factory. On the table here I also have an East German Komet dryer, probably modeled on pre-war Siemens dryers, with an instruction manual. Once upon a time, I showed this dryer because it was made in the factory in Suhl,

Where, among other things, vacuum cleaner engines were also made, which were imported to Poland in the late 1950s and also installed in Polish vacuum cleaners and Polish devices. We will definitely pay more attention to this dryer.

Yesterday I had the opportunity to borrow several of my exhibits for the exhibition in Olsztyn, including a very cool and very interesting, probably the first post-war Polish factory hair dryer. from the then Bicycle and Baby Stroller Factory in Rzeszów, i.e. from the later Rzeszów Farm Equipment Factory, i.e. from the even later

Zelmer plant. I devoted an entire long separate recording to this dryer, you can see it. And I am very happy and thank you for inviting the organizers that this dryer will now be able to be presented at the exhibition in Olsztyn from mid-March.

I took a few more German dryers there: an AEG dryer and a Foen Gnom dryer. So I’m very happy about it and I think that these dryers will be a small but sensible addition to the Olsztyn exhibition. However, today, as I said,

I would really like to see the one in my collection, probably not the oldest one, because this Komet dryer comes from 1963, this Fema dryer comes from 1965, but out of all this collection of Fema dryers, it is the oldest model

And the one that somehow I particularly like it and which I would really like to take a look at today, because I admit that I haven’t even opened the dryer yet and there’s clearly something “flying” inside it. I don’t know if any engine mounts are damaged or if something is loose.

I would like to check it and, first of all, I would like to see if this dryer works at all. For now, the only thing left on my workbench is this Fema dryer from Zakłady Wyrobów Elektrotechniczne Eltra in Bydgoszcz.

Let’s take a look, as always, first at the nameplate. Here we have the symbol of the Bydgoszcz factory, we have the Made in Poland marking, we have the RSW-1 type of dryer. I immediately wanted to ask those of you who have a little more experience and knowledge

About old Polish dryers. I don’t know how the first RSW-1 dryers differed from the SR-1 dryers. I don’t know which one came first. I assume these are RSW-1 dryers, but I’m not sure. Unfortunately, I don’t have the SR-1 dryer from Eltra yet.

I would really like to compare these dryers. Perhaps then it will be clarified which of these models was the first. Here we have the voltage, network frequency, here we have the power of 425 W, here we have the production date, in this case 1965.

I also saw the RSW-1 type of dryers from 1966, probably not newer ones. And here we have the serial number: 2062 copy of this dryer. The dryer appears to be in fairly good condition. Fortunately, it is not cracked,

Which quite often happens in the case of those made of – I am not sure whether it is made of bakelite or phenoplast. If anyone of you has more knowledge about the materials used to produce this type of equipment housing, please let

Me know. I read somewhere that they seemed to be dryers made of phenoplast, but I’m not sure about that. I don’t know anything about this. In any case, it is not damaged. There is one screw missing here, perhaps this is the reason that you can clearly hear some moving element inside.

This dryer is equipped with an original cable and plug. Here someone has clearly cut out a piece of the plug, probably so that it can be used in sockets with a grounding pin. The dryer is equipped with two switches. One switch turned on the cold air flow,

The other switch turned on the heater or heater and the dryer then started blowing warm air. A very interesting story is related to the design, appearance and form of this dryer, but I admit that I would not like to talk about it in this recording because I know that it will certainly

Be the topic of the lecture opening the exhibition in Olsztyn, which I have already mentioned and I would not like to talk about it. reveal these curiosities prepared by the organizers.

However, after the opening of the exhibition, I will be happy to come back to it and we will definitely show a certain dryer, which is not even a very distant cousin of the Polish Fema dryers. Speaking of the Fema dryer, there is this characteristic Fema inscription on the casing.

And that’s probably all that can be said about this dryer. I looked for some information in the technical literature in a book that I have already shown several times on this channel: in the book “Electric home appliances” by Jerzy Małaszuk, published in Warsaw in 1972.

There is a whole chapter devoted to hair dryers, actually it is part of the chapter “Heating devices with an electric motor”, which also discusses for example, fan heaters or some ovens. However, the most interesting and, for us, the most important part at the moment is the part devoted to hair dryers

And I would like to show you a few diagrams, some graphics and read this very short chapter to you, because it can be quite a nice addition to the knowledge about the design of this dryer and subsequent similar ones. In the part of this chapter about hair dryers we can read:

They consist of the following assemblies: electric motor, heater, thermal bimetallic switch, double switch – the one we have already seen here – housing. The operation of the domestic dryer type RSW-1 will be described in great detail – exactly the one we see today in this recording – because it is commonly used

For drying hair – and now attention – in painting and photography works, for example for drying drying photographic prints . The dryer allows the flow of cold air when the heater circuit is turned off, i.e., as I said, after turning on one of these double switches.

Hot air flow is achieved when the heater is turned on, i.e. in this position. The heater has an automatic thermal bimetallic switch that protects the dryer against excessive heating and damage to the heater. You turn on the dryer using the main double switch, like the one here, which is located on the housing.

The switch allows you to turn on only the engine or the engine and the heater at the same time, as is the case here in this position. The technical parameters of the RSW-1 dryer are further described here: total power of the dryer: 425 W, exactly as written on the nameplate.

Heater power: 400 W +/- 10% Air flow rate of an efficient dryer from 0.75 to 2 liters per second, air temperature at the outlet from the nozzle: 60 degrees Celsius +/- 10% maximum activation time of the thermal bimetallic switch: 15 seconds increase in temperature of the parts touch: 40 degrees Celsius,

So there is no fear of getting burned by such a dryer. Temperature of the outer surface of the nozzle during operation: 100 degrees Celsius. Electrical strength of insulation 2500 V Length of the mains cable: 2 meters +/- 5%

Well, I haven’t checked it, but it’s not that important, it looks like this cable is quite long. And it is here – it will be interesting for us and we will check it in a moment – the mentioned IK-71 type engine,

It is written in brackets that it is a motor imported from Hungary with a power of 25 W. Maybe we will move on to the description of possible repairs in the event of damage to this dryer in a moment . And now I would like to open this casing and look inside.

First of all, I would like to check whether this dryer actually has such a Hungarian engine installed. I’ll put the book aside for now. And let’s try to disassemble the dryer casing.

Here is one of the screws – I feel a bit sorry to have to do it, but it is probably still sealed from the factory, so I have to scratch the sealing off. On the one hand, I don’t want to do this,

Because it is clearly visible that the dryer has never been opened, but on the other hand, we simply won’t be able to check what it looks like inside. Oh, and I think it worked… Yes, I already have access to the screw here. Fortunately, there is no danger of losing the warranty

Of this dryer, because I have the impression that the warranty expired in 1966. Okay, here two nuts fell out from the other side. And the last screw. Actually, the dryer is held together with four screws, but one screw is missing.

Oh, and here too the cap has already fallen off, I’m pushing it aside. And I think that now I will be able to open the casing. And now we have a very nice view of the entire structure of this dryer. Maybe I’ll turn it around…

Oh, I think this way the individual elements of this dryer will be very clearly visible. And here, in the book by Jerzy Małaszuk, which we are looking at today, there is also a diagram of the construction of exactly this model of a dryer. We can watch it here.

I will show you this diagram right here on the side. I think this place will be good because the drawing won’t disturb us. And here we have the individual elements of a hand-held electric dryer described in this diagram:

1 – dryer cover, 2 – IK-71 type motor – this one, we will see in a moment, we will unscrew this motor and see if this type of motor is actually installed here. Blade rotor – 3. Here we have this rotor made of plastic blades.

4 – here the heating element. Here we have this entire heating element with resistance wire wound on such a scaffold. 8 – electrical contacts, here in this place, allowing you to turn on the engine itself or the engine and the heating element.

9 – rubber strain relief, here it protects the cable against breaking or excessive bending. 10 – tape strain relief, I think this is the plate that holds the cable in the housing. And 11 – wires and this is actually the entire structure of this dryer.

And here we have this bimetallic switch that protects the heating element from overheating. And here we also have a cover for the outgoing air. Actually, this is where the entire philosophy of this dryer ends. Here in the book we also have…

Oh, maybe this way it will be visible and of course I will also display it here. We also have a connection diagram for the RSW-1 dryer. 1 – double switch located here, 2 – electric motor, 3 – radiator and 4 – thermal bimetallic switch.

It is all marked here and I think that now with the dryer open you can see the connection diagram of individual elements very nicely. I’ll put the book aside for now, it will come in handy in a moment when we’ll talk about simple repairs to this dryer.

And now maybe I’ll zoom in a little and look inside, let’s see first of all this engine, whether it will actually be a Hungarian engine. And I can even see that it is not an engine imported from Hungary, because even without removing it,

You can see the inscription Made in Poland on this engine, but unfortunately I do not see any marking of the type of this engine. So I’ll have to unscrew it in a moment. Maybe there’s something on the other side.

Oh, I think it will be clearly visible now. Perhaps even in the recording, I’m not sure, here at this point you may even see this inscription, a sticker with the inscription Made in Poland. However, I think that to remove this engine it is enough to unscrew these two screws.

By the way, now I look at it and wonder what was making so much noise when this dryer was assembled, because to be honest, I don’t see any loose parts here. Let’s see, let’s take this engine out… One screw. Second screw. I may be able to remove the engine now.

I still need to unscrew the screws a little better. [Music] Okay, also from the other side… Here, I won’t extend the engine any further because these wires are holding it. However, I’m trying – so that these two screws don’t fall out – I’m trying to tilt the engine and look,

Find some marking somewhere, but I admit that I can’t see it anywhere on the side. There is probably only a technical inspection stamp. I’ll try these wires soon, but it might free them here. There is also a metal clip which, if bent, will allow me to remove the engine better.

Besides, I would also like to clean the engine from the other side, because it is quite dirty there. Oh, I’ll just bend this buckle a little bit. And now I can take the engine out, and then I’ll put this whole clip back in here.

Now we have the engine removed, it is a little dusty, not very dirty. After turning this engine over, unfortunately I don’t see any inscriptions on the back. Let me get some brush. It is very possible that the first models of the RSW-1 dryer used imported engines.

And then the production of Polish engines for this type of dryers began. However, at least I don’t know where these engines were manufactured and what their markings were. There are certainly no inscriptions on the engine on this side. Oh, it seems to me that it is

Not very clear here, now after cleaning it is a little better visible, the sticker with the technical data of this engine. Unfortunately, they have faded a lot here, and I think even some of them were damaged by the engine blades.

I admit that I had to use a small magnifying glass to be able to read these very faded inscriptions. on this engine, but the logo of the Tonsil plant, i.e. the Speaker Manufacturing Plant in Września near Poznań, is clearly visible here

. It seems to me that the name Tonsil has been in use since the early 1960s, and certainly back then the Tonsil factory or Tonsil plant was part of the Union of Electronic Industry UNITRA and produced primarily loudspeakers, but also various types of engines and motors for radio tape recorders.

Audio equipment enthusiasts will know much more about it than me. However, when I started to look at this type of engines, I can clearly see the SAZ-2 engine type in this lighting. And when I was searching on the Internet, I found several very similar engines

With the marking of the Hungarian manufacturer IMI, i.e. the engine factory that produced, among others , other engines in the late 1960s imported by the Rzeszowska Fabryka Sprzętu Gospodarskiego and installed, for example, in Alfa II vacuum cleaners. We’ve probably seen two or three engines of this type.

I also saw an IMI fan motor somewhere. Well, here we are clearly dealing with Polish production, with the SAZ-2 engine from Tonsil near Poznań. I think it should be written somewhere here, there is an inscription that this is an engine designed for continuous operation with forced cooling,

But it is quite unclear. However, it seems to me that the production date of 1965 is quite clear here, I even know if it is not X, i.e. October. Well, in any case, 1965 was quite clear. Other details on this label are unfortunately very, very blurry.

Maybe I will be able to get another motor of this type, maybe in the slightly newer Fema SR-2 and SR-3 dryers, then we will see. I admit that even in my search for this motor I reached into the catalog of motors from the 1960s,

But unfortunately these are only single-phase commutator and DC motors. There are no such small engines here. However, I found engines of this type in the “Low-power electric motors” catalog from 1984, which is 20 years younger, published almost 20 years after this dryer.

However, here there are engines of a very similar type, only newer. Single-phase induction motor with an auxiliary short-circuit winding, types SAZ-21, SAZ-21a, SAZ-21b, SAZ-21d, SAZ-21w. The engines are designed to drive hair and hand dryers, fan heaters, chimney fans and other common use devices.

The structure and properties of such a motor are described in detail here, but maybe we will see it when we come across such a motor in a newer dryer. Well, here the manufacturer is given as the Silma Small Power Electric Motor Plant, Sosnowiec.

And here is a diagram of a more or less similar engine, not the SAZ-2 type, but a newer version. Well, anyway, we saw what engine is in this dryer. I think now we can reinstall it here, attach these wires, put it all together and see how this dryer actually works.

Okay, we can reinstall this engine right now, but I think it would be more convenient first , while the engine isn’t exactly sitting here yet, to install the plate holding the wires, and this is important, because otherwise the wires will catch on the rotor blades. Okay, I already have one fitted here.

This plate is pressed into place. Okay, I think these wires are already held nicely here. I’ll just bend the ends of the plate a little so that they don’t slip off. Okay, this should hold nicely.

Now I can bolt the motor here to the two mounts in the housing. Here you just need to hit them with the screws. Okay, this screw is in and screwing in. Let’s see what happens with this screw. Well, is he coming in? He’s coming in!

I tighten it, not too hard, so as not to tear it out and destroy the casing. Cool. It is important that these cables are – oh, you can see it now – held, as I said, so that they do not catch on the rotor blades anywhere.

Okay, this double switch slipped out here, so I’m putting it back here. These wires fit nicely here. Here, by the way, you can take out the tablet. This is not a sticker, it is actually a nameplate made on some aluminum sheet. You can put a plaque here.

While we have the dryer open, let’s take a look at the “Electrical Home Appliances” book again, because it also describes quite nicely possible repairs that can be undertaken in the event of any damage to this dryer. So here it is: You can start repairing the heating element after disassembling

The two-piece casing of the dryer, as we did now. After removing the right part of the housing, the lead wires are disconnected by desoldering, and then you can easily remove the damaged heating element – this one, i.e. here you just need to unsolder

The visible one – I think – here, the fastening of the wires to the heating element. The burnt heating coil must be replaced with a new one. This is about the resistance wire. However, the body of the heating element can be left, i.e. the entire – in quotation marks – “scaffolding”

Around which the wire is wrapped. The automatic thermal bimetallic switch – located here at the front inside this heating element – if burned or deformed, can be repaired by cleaning it or shaping it to the correct shape. If the catch is broken or worn off, the entire switch

Together with the heating set should be replaced with a new one, because gluing does not guarantee long-term operation. Removing the malfunctioning or damaged main switch – located in the handle – double for repair, is possible after removing the left part of the dryer casing. Damage such as a bent lever or

A burnt contact can be removed by reshaping or cleaning. This means that these plaques can be easily straightened or cleaned somehow. It is better to replace a damaged switch with a new one of the same type. The nozzle housing and cover are made of plastic and are therefore relatively brittle.

This is what we have already talked about. Quite often, the socket of the hole for the connecting screw is damaged. Yes. In such cases, if it is not possible to replace the housing part with a new one, you can use

Another non-standard screw with a nut for connection, placing a washer under the head or nut of this screw so as to cover the entire hole. We screw together this type of connector. A minor crack in the casing can be glued or bonded

By riveting. A very thin copper or aluminum sheet is then used as a washer . A damaged nozzle cover must be replaced with a new one. So that’s it. If such a cover cannot be purchased, it must be made, for example

From a fine copper mesh. Damage to the mains cable on the dryer side can be easily repaired by shortening and re-installing the cable. Please remember that the strain relief and rubber strain relief are assembled correctly. Electric hand dryers are mounted on the wall. And further:

Their faults and repairs concern three basic assemblies: the engine, the heating element and the main switch. We will talk about such wall-mounted hand dryers on another occasion, because I have a very nice Zelmer hand dryer from the early 1970s. I will definitely show it in another video.

I was wondering what was making such a knocking sound in this dryer housing and it seems to me that it is the entire rotor and the fan that are loose. It clearly moves a little here, has some play, and probably when you move the dryer, this fan may cause this rattling noise somewhere.

Okay, but I think that as long as it doesn’t rub against the housing, it shouldn’t matter much. Now we can use the fact that the dryer is open and we can see what it all looks like in action.

You just have to be very careful, because all these elements, here the switch, this heater, will be under voltage, so I will only hold the dryer by the rubber cable cover. However, I will connect it to the power supply here.

Now, after turning on the power strip, the dryer should start immediately, because I can see that the engine power is on and the heating element is also on. I turned off the dryer immediately. I don’t know if you noticed it in the recording.

This is where these heating coils started to heat up slightly, because at this point, when this dryer cover is missing, the air simply disperses from this fan in different directions and there is no adequate cooling of this heating element.

And like I told you, there’s this thermal switch here. If all this were to overheat, this plate should break the circuit. However, later, to bend it again and close the circuit, you will have to press this tiny lever. I’m going to turn on this dryer again for a moment.

Yes, and as you can see, the dryer starts working immediately. I won’t bother it any longer in this open state so as not to burn out all the elements of the heating coil. Taking advantage of the fact that we can remove this heating element, I would like to show you how this

Switch works to protect the heater against overheating. Notice how the contacts are connected to this element: one of them connects to a metal element on the inside of the entire body, on which the resistance wire is wound. And the second one connects to this plate that goes through the middle here.

And for this wire to start glowing, there must be a closed electric circuit here. However, if these elements overheat, there is a metal element with something like a tooth. Then, if it heats up to a temperature above 100 degrees,

It will lean to the side and notice: it releases a spring that disconnects the electric circuit in this place. The heater is currently turned off. Even if voltage was applied here, the heater would not heat. And that’s why there is such a tiny lever here, so that

After the heater has cooled down, it can be conveniently pressed. Then this tooth again blocks the spring, the plate in such a position that it comes into contact with the housing on which the resistance wire is wound, closes the electric circuit and again this heating coil, this resistance wire can heat up

And in combination with the air coming out of the this fan to ensure the supply of warm air. However, if everything overheats again, this lever will move to the side, disconnect the circuit and the dryer will stop heating and there is no danger,

Or at least there is less danger, that the entire heating coil will burn out. A pretty cool, clever mechanism that could be tested in action someday. For example, remove these motor blades, connect power to this heater and see if the overheating protection actually works. We will see it again after assembling this dryer.

In fact, I’d have to disconnect it now to be able to see it. Okay, this way. And if I assemble this dryer, it should not heat even after turning on the heating, and only after pressing this lever

Should I close the circuit and the dryer should start heating. Maybe let’s do it like this, o… It will now be disconnected, and after closing the dryer we will check the operation of this protection. Okay, here I’m putting this whole heating element back

In such a way that now it shouldn’t even if I turn on the heating switch here, it shouldn’t work. Of course, I also put the air outlet cover that I removed here. And I think now we can close the dryer casing. This switch is held here.

I admit that I am not entirely sure where the rubber band that fell out of the housing was mounted. It has obviously come loose somewhere here, but I look at the diagram of the dryer and I don’t really see where the rubber band could be mounted. I don’t see her anywhere here.

I think this rubber band was just slipped in here, right, and secured these wires, oh, okay… By the way, it’s also here in this diagram. I just didn’t look at it. Well, now I think we can close this lid. For now, I took the screws out of it

So that they don’t fold up somewhere. You have to be careful that the switch… Here the switch has a pin and this pin must go into the hole provided for it on the other side. The nameplate must also slide into the space provided for it here.

Here I have to tilt the switch a little. Oh, it went in… Nice… The most important thing is not to press anything too hard, not to bend anything and not to crack the entire casing. I think the casing is nicely fitted. It’s worth checking to see if the entire heating element is bent,

But no, it sits nicely here. The plaque sits inside. The switch on both sides entered the housing here. Now we can twist it. Just be careful because these screws have different lengths. The shortest screw will be used here in the handle. We can do it right away.

I hold the cap on one side. Now I think the cap fits. On the other side I insert this shortest screw. So I tighten it. Not too much for now. This is where the entire cable sheath sits well.

Okay, now I’ll take – they are already the same length – a long screw and I think I’ll turn it… There was one screw missing, but let’s say that there was definitely one screw here near the switch. I have to put the nut in there to make it fit.

Oh, now the screw is in, it’s already screwing in. Okay, I’ll tighten it more later. And I think I’ll also put a screw in here at the end, I’ll put a nut in here. Okay… I’ll tighten it a little more, but not too much, because, as it was written in the book,

These screw sockets can crack quite easily. It seems to me that the dryer is already quite well assembled and fitted together. I guess all the pieces fit together. Let’s test it now. We saw that it works after opening the casing. However, now I would like to see how it works after assembly.

I will connect the dryer to the power supply. Let’s just remember that we have specially turned off the safety switch here, which protects the entire heating element or heating coil against overheating. So now I think that even if I turn on the warm air, the spiral will not work.

We will only have to press this lever for the switch to click, return to its position, connect the circuit here and only then will the spiral start to heat up. But we’ll see that soon. Let’s first turn on the power and cool air.

This works pretty cool. The dryer blows nicely, but with cold air. Now I turn on the warm air, but nothing happens because this emergency switch is turned off. I’ll just press this lever… I connected the contacts here and the dryer starts blowing warm air very nicely.

And I assume that it will remain so until there is no risk of these elements overheating. Then this switch will disconnect the circuit again and the dryer will stop blowing warm air. You will have to press this lever harder here and only then will this entire heating element start to heat up again.

I think it works quite nicely. And that’s probably all for today. As always, thank you very much for the opportunity to look at another old device together. This time we saw what I think is the iconic old Polish hair dryer RSW-1 from 1965, manufactured in the Eltra factory in Bydgoszcz,

Not yet in the factory in Kętrzyn. I thought it would be a bit shorter, but there was still a lot to see. We saw this quite interesting SAZ-2 engine from the Tonsil plant, which is located in this dryer. We looked at the structure of the entire heating element,

The heater located here and the switch that is theoretically supposed to protect it against overheating. I don’t know if this actually works in practice. And I am very happy that in the next recordings there will be an opportunity to see more models of this dryer.

As I showed you, the SR-2 model from Eltra in Bydgoszcz and the SR-2 after production was transferred to the factory in Kętrzyn. We will also see such a Fema SR-3 dryer, also from Kętrzyn. And if you are fascinated or curious about old hair dryers, not only Polish ones, their technology,

Their history, curiosities related to them or in general their design, their form, then be sure – as I already said in the introduction to this recording – make an appointment. in mid-March for a visit to Olsztyn. It will definitely be worth it, because the exhibition organized there

Will present a whole range of very cool and interesting exhibits. I think that almost all, if not all, Polish dryers, especially those produced in Farel in Kętrzyn, because it is related to the history of the region around Olsztyn. For now, as I said, I am not revealing who is organizing this exhibition,

What you can see there and where it will be, but I hope that in a few days, when the organizers of this exhibition publish the official invitation, I will be able to include it in the description recordings, detailed information on where to go to such an exhibition.

This is a dryer manufactured in the Zelmer plant in 1972. There is no heater here, as in these hand-held dryers, there were only two such bulbs powered by a total power of… Yes, the total power of this dryer is 775 W.

I don’t forget about old vacuum cleaners and old power tools. Just today I received a package with another old drill, which I will definitely want to look at with you. That’s all for today, I’ll play around with this dryer a bit, play with it a bit,

Read a little more about dryers and the motors used, motors also used in slightly newer dryers. Thank you very much again and see you soon, hello!
