I have a mini airbrush compressor which I wasn’t able to use for a few months.
Today, I was about to use it but suddenly it leaks air.
The compressor works and can produce air.
But after a few minutes, I can hear some air leaking out of the compressor.
I put a red mark on the picture where the air leaks out.
I am not sure what part of the compressor that the air leaks out.
How do I fix it? Please help me.

Mini airbrush compressor leaking
Well renzyboi, the obvious question is, have you tried tightening the bolts?
From the image it would seem that air is leaking from the pump housing.
Also, check the in-tank check valve to make sure it is working. See how to on the check valve pages on this site.

Airbrush Compressor Leaks Air
Hi Bill thanks for your reply.
Yes I have tried tightening the bolts but it is still leaking.
Compressor can produce air and works but after a minute, It is starting to leak air.

Leaking
That would suggest that as the tank pressure grows, your compressed air possibly cannot flow into the tank easily and that’s forcing air out of the seals of the pump head.
That’s a gasket leak for sure, but why?
Once again, assuming there is one check the in-tank check valve to make sure it is working.

Where is intake check valve
Sorry to ask but where can I find the intake check valve?
There is one ring that when I tried to pull, air was being released from the tank. Not sure what is it called.
Thank you.

PRV is the ringed part
What you pulled the ring on was the PRV.
Typically there is a fitting where the air line from the pump enters the tank and again, typically, that’s where the tank check valve is located.
Do you have a manual with a parts list?
Please have a look and see if it identifies it, and then let us know.

Hi Bill, I picked up na old Oil Tanked Air Compressor from an estate sale that the former owner used for his airbrushing indoors. It runs great but the fisheye indicates it could use some oil. The old ID markings as to make & model are toast, it does have a clear oil type label still marked “Olio Huile Oil” which I googled and appears to be 15W/50 Oil. The questions are as follow based on the photos Im including… 1. Do you know what in the hell this thing is? 2. Will synthetic 15W/50 Oil from NAPA (Qt) work… Read more »
I don’t recognize the make, yet it does look like an older Jun-Air compressor to me. There’s a page about them on this site. The pin hole, if it is in the tank as it appears, signifies to me that the inside of the tank is corroded, and no, I would not spot weld it. My recommendation is to replace the tank. The “oil out” is probably by unscrewing the sight glass and tipping the unit forward until all the old oil is out. I am guessing that new oil is poured into the same hole, filled only to the… Read more »
Agree, except Bambi pump, I think.
David, you might try sending some pix to Bambi and see if anyone recognizes it.
I’d wager the pump is at least similar, if not identical to recent Bambi MD pumps. You can open it up to see.
