/ @ajrestoration I bought this old Rotary Vane Compressor from an old lady on Facebook marketplace. I never saw one like this before and I had to have it, also I thought it would make an exciting video for you all!
I hope you enjoy the video.
If you have any suggestions for improvement, or compliments share them below!

Thank you all for your support! I appreciate all of you!
Rotary vane compressors consist of a cylindrical casing, two openings - one suction and one discharge - and a rotor positioned eccentrically with respect to the casing. Compression occurs by refrigerant flowing into the chamber where, due to eccentric rotation, there is a reduction in the desired volume.
It's used as a vacuum. I worked for a printing company, and it was used on a machine that guided the rolls of paper through the printing press.
Thank you so much 😀 I wondered what it was used for!
I was just thinking the same thing.
Ya
Yeah thats what i was going to say. We had a small Jet press where i used to work that had the exact vacuum pump in it.
I just repaired a very similar pump at work last week, those vane type pumps are normally used for vacuum, not great for pressure. The ones we have all have an oiler on the suction side, so the pump is constantly pulling in a tiny amount of oil to keep the vanes from wearing out or overheating. Someone let the oil run out and the vanes were stuck, just had to clean them and fill the oiler. The more powerful ones we have the entire pump head is enclosed in a "box" full of special vacuum pump oil.
Not 100% sure, but that looks like a Gast pump. Typically rated about 20" Hg vacuum to 10 PSI pressure, IIRC. They're used in various settings where moderate vacuum/pressure is needed and long life with very low maintenance is desirable. They use a very similar model as an aerator pump on those home sewage treatment installations you get stuck with when your property is not suitable for a normal, buried septic tank & drainage field. Those pumps are rather pricey new. There are lubricated & non lubricated versions. As yours does not have a wick on the suction side & appears to have carbon vanes, I believe it is a non-lubricated model. That should be assembled totally dry, you should not have injected the oil into it.
BTW, very nice job on the restoration. I thought you were a bit demented when you started spraying the red paint, but it looked really good when assembled.
Its a GAST dry vane compressor/ vacuum pump. I have one in my garage for doing vacuum bag composite work. Problem is you need to disassemble it and clean the oil out of the compressor section, its meant to operate dry. Lots of teardown videos online, rebuild kits are available from GAST
I work with these pumps currently, we use them as vacuum pumps on envelope inserters. The graphite vanes wear down every 1000 hours or so and blowing out the exhaust filter is one of the most entertaining parts of my job, it just never stops blowing dust.
You could make yourself a really nice vacuum pot for resin casting with that pump.
Considerate engineering. They made the part most likely to break, the glass jars, standard canning jars.
There really IS a first time for everything. 🤣
Great job. Nice colour scheme you picked. Car air horn compressors use the same principle due to low noise and high efficiency. Highly efficient compressor.
Vacuum pumps are used for many applications including food packaging, woodworking, pick and place etc…
Very cool. You did an excellent job with the restoration. Thank you for sharing!
Thank you very much!
Very nicely done
Thank you very much!
Hard to appreciate when you don’t know what it does. Happy to watch more cast iron cookware.
That must be the most original looking Doerr Air pump in the world! Great Work!
These pumps are also set up as a "push" orientation and used in supplied air respirator systems. Mostly used for industrial applications like automotive painting, urethanes, welding. Anything that can't be filtered out effectively (isocyanates), you would use a SAR system. Same concept for medical research labs that use positive pressure suits. These are just smaller versions. And before anyone asks, no, you can't use a compressor for this task. The pump would use oil, and when you compress oil you also make carbon monoxide (you could with a complex filtering system). So the rotary vane compressor/pumps are the option for respiratory uses.
Beautiful restoration good job mister
Very nice restoration
RCA used a similar unit as a vacuum pump in their quadraplex 2" videotape machines of the 60's, 70's and 80's.
The vacuum was used to draw the 2" tape to the guide surface of the air bearing head wheel. I have replace a few of the carbon vanes in my time. I think the RCA pumps were sourced from Bell and Gossett.
You should not oil this pump. It is oil-less. The graphite vanes provide their own lubrication. Oil will combine with the graphite dust and cause them to get sticky and won't slide in the slots properly.
18:40 The rotor is turning backwards ❌ and the pipe threads are assembled with thread seal‼️
It makes a good seal as is, and the rotor is not turning backwards, even if it is, if the vanes are installed the correct way, all is good.
Thanks for sharing mate always good to watch your videos love and peace from Ireland
It is carbon vane compressor (vacuum pump). It did not need oil inside. Carbon vanes may collapse.
Cool restoration 👍👍👍
Oh man, I had to use one of those at an old job. It was such a freaking pain in the *** at times. If you got any liquid in the thing, it would be an almost automatic game over. Cool thing is you can use WD40 to help re-prime the thing if you have issues with the oil.
Nice restoration but did I miss the vanes going in?
You have talent
Nice restoration well done 👌👍
Many many thanks buddy!
Well done👌
Thank you so much 😀
I have a similar compressor (albeit quite smaller) with the same rotary vane design, and it was a nebulizer (for medical use).
It's a shame you didn't keep the labels on the jars, or showed them. Did they tell what was this device was used for?
I could barely make out what it said, I did order new old stock filters but they were a different thread size. Ill get a reducer some time in the future.
Really nice job... Keep doing the electric motor refurbs and I may get the guts to try one myself... Mechnicals OK for me, electric, not so much!!
I worked for a company that used the same pump. We used it in vacuum mode for paper handling in a printing operation. About the only thing that fails is the carbon fiber wafer breaks or locks up to bearing failure. It runs with no lubrication and it runs very hot.
Super. 😊
عمل رائع 💪🏻
On the tab it said 110v ac. How did you change it to 220v. Looks wonderful.
Another great video, man! Keep it up! 👍
Thanks! Will do buddy!
Waw😯❤🌟 very nice
Many many thanks.
hi.. this is a vacumm pump. to hold things dond on a table
@16:37 - that lock nut is on the wrong way around. Besides the oil, already mentioned, this is a very nice restoration.
How can you put a locknut in the wrong way ? Are you any good at anything ?
WE USE THESE FOR SUPPLY AIR FOR OPERATORS WEARING HELMET TYPE COVERING WHILE POWDER COATING
nice👍😘
Hola activa los subtitulos para saber bien que pasos haces, gracias
Seen those in dental office
I think that it is a vacuum pump and not even a compressor at all.
What do they do with the things they have restored?
Hey, how long have you been working on small engines? I am just starting to advance my mechanical knowledge from automotive to small engines. Any advice because for some reason I am having trouble in retaining simple applications of the engines. I know they are basically the same as bigger engines but they are truly quite different all on their own. Any advice would be greatly appreciated. You do absolutely amazing work.
👍👍👍😎😎😎
My neighbour: noooooo your disturbing my peace.
Me: Compressor goes brrrrrrr
from brazil congratulations friend great work you are a professional 👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻
Those square black pieces were the carbon brushes right?
Should used pipe dope or Teflon tape on the inlet and outlet sides.
Hi,
Good job
But the capacitor cap was Installed in the Wrong direction!
Nope, those caps can be installed any way around. If it was installed wrong it would pop. Or not work at all. When caps are pole sensetive they will have a + and a - indicated.
@@AJRestoration Yes, this capacitor does not have polarity.
I mean the cover on the capacitor!
Its a compressor that goes to a folding machine in a print shop
Ek mis die stormer/bulls game vir jou
Natuurlik sal jy. Die is beter
Haha julle manne maak my bloos!
very slowly, sometimes you want to break the monitor, although it is not to blame for anything
Hit the monitor hahaha I dare you.
Fix it up for good
... молодец ретромастер!-, восстановил раритет, дал вторую жизнь старой вещи, честно говоря, я такого компрессора никогда не видел, плохо, что нет перевода на русский язык, дай бог тебе здоровья и благополучия, новых творческих успехов 👍👍👍😜🤭😉🤔👏👌🇷🇺👈!!!
какого такого?.. обычный вроде бы. но это скорее не компрессор а вакуумный насос
hello, sir. what is that 09:40 🐙
That is a bearing puller.
Oh jesus....please don't use steel wool on the bore for a pump or engine bore.
Its fine, light pressure was used and the steel wool is a fine grade. No damage were done. :-)
@@AJRestoration OK good, I know how to rebuild car engines, so I know never use steel wool on the bore of an engine.
high quality and robust motor brand,why not pink color🙂
Well it's a common air compressor design i opend motor of pressure horn from my car । It has same setup but in minature version । It had an oil port to lubricate those vanes । If not they tend to jamm
Must be a german motor...
I also think so.
А почему масло не залил, и на трубки фум ленты не намотал.
First
Indeed haha
sound not good .
i hate the color 😒
