Ridgid 6 gal. pancake loses air

by john

I have a Ridgid OF60150HA 6 gallon pancake that reaches its expected 150 psi and shuts off.


But it gradually loses air pressure to 125 psi before holding. This takes about 15 minutes.

Although my air tools only require 90 psi, this is frustrating because it recycles more frequently than expected.

Is it possible the manufacture's installed check value is set at 125 psi?

Ridgid pancake gradually losing air
by: John from Kentucky

Thank you for your suggestions. Bill, you are correct in understanding the gradual loss of air for 15 minutes. Ironically, this is a new compressor from Home Depot and it is a replacement for another that seemed to do exactly the same! This time I used the replacement to complete a small project. Since it is under warranty and I am still within HD's return period, I'll return it before pulling the check valve. Probably will get another brand. I did get some valuable insight from all who gave advice. Thank you all.

air leak?
by: Roger

simply let it run and reach the top pressure and then use a soapy solution and spray all connections to see if it bubbles.

After you've done what Bill mentions, if it STILL leaks and you can't find the leak, there is a possibility it's leaking inside the gauge.

Rare, but it happens.

Ridgid compressor losing air
by: Bill

Hi John. Typically a check valve has no "setting". It's a one way valve, meaning a flapper or ball opens when air is flowing one way, and shuts when air tries to flow the other.

It is interesting that your air loss takes 15 minutes, and then it stops leaking at 125 PSI which is what I understand from your question.

The air that is leaking has to come from somewhere, and that somewhere is the tank. If the air pressure is dropping the source of the leak, with the compressor off and no holes in the tank has to be the tank check valve.

I suggest you drain the air to zero PSI, pull the check valve, rinse it thoroughly in solvent, let it dry, and reinstall it. I suspect that at 150 PSI the seal in the check valve isn't secure allowing a bleed down to where the valve can seat against the 125 PSI.
