Air Compressor Impaired

[tnshaw]

New to this forum, but I have noticed that there is a large amount of knowledge here. So, I picked up this air compressor for $100 as I am looking to paint my first car. It runs great, but I have no idea what it is and the other part I can't figure out is where to drain/refill the oil..... Any input would be greatly appreciated.

the lh bottom is the drain, the top right plug is the fill.
how is the tank? what is the motor rating? 3 phase?

Look familiar to me. This thing is 40 years old and still works great. Speedaire. First pic is with original tank. Replaced it when I got a pin hole.

Just watched a video, have the oil drain/fill figured out....

Thank you! Motor is currently wired for 110V on a plug. Tank seems good. It holds pressure and nothing ugly comes out when I drain the air....

If you can you'll want to run it on 220v.

Another question, is this compressor a single stage or two stage? How would I tell?

Thanks. I plan to rewire it for 220v as I do have a plug for that in my garage.

Hi Tarmy, a 20g I just picked up looks identical to yours except it is a Dayton. May I ask how much PSI yours gets up to? Mine makes it up to 100 before shutting off automatically. The motor on mine is Model No. 9K322P.

P.S. I currently have it set up for 115v - no 230v available yet.

It's a single stage. 2 stage has a line coming out of the head from one cylinder and going back into the head for the other cylinder

I think Dayton and Speedaire are the same…not sure. Mine gets to 120/130 on 240v

Also, 2 stage has one small cylinder and one big cylinder
