Mini airbrush compressor

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.

PRV
by: Bill

What you pulled the ring on was the PRV.

Please see the pages on this site about the various components on the compressor to better understand what they are and what they do.

The information is already all here for your use.

where is intake check valve
by: renzyboi

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.

Leaking
by: Bill

That would suggest that as the tank pressure grows, your air cannot easily flow into the tank, and that's forcing air out 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.

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.

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.
