No pressure on Rigid OF25135CW

by Eric
(Winslow, AZ)

My air compressor stopped producing pressure in the tank.


The engine runs fine and I can feel air blowing around the engine, but no pressure is built up in the tank.

The gauges read 0. At one point, I tried it again, and it did pump up pressure for a while. Then I noticed I didn't have any pressure even though the compressor was still running.

Have not been able to duplicate it running again. Is this a matter of gaskets and the flat valve? Or should I order the whole pump assembly to fix this?
______________
When an air compressor is running, there may be air blowing around the motor, as some compressor motors have a fan on the motor shaft to help cool the motor.

I don't know if your model has a TEFC motor, so that would be the first check.

If it does not, then why is air blowing around the motor?

If you pop over to the sitemap page, and look under troubleshooting, you'll find links to pages that will help. Try the one that is about why air compressors run and don't build pressure.

After you've done some of the checks noted, if you wish, add an update here as a comment so we know what you found.

The motor does have a fan in the back of it, which does create a lot of blowing air. However, there is a lot of air toward the front of the motor that is away from that fan. I disconnected the main line that goes from the compressor to the tank. There is air going thru it. I'm not sure how air pressure there should be. I imagine there should be more pressure than is going thru the line. I can hear a pit, pat sound thru the line as it pumps. Turning off the compressor, and manually turning the fan blade with my hand, which turns the piston, I can hear that same sound as the piston pumps.
I am thinking that there must be a blown gasket??
A complete pump assembly, which includes flat valve, new piston, and all the needed gaskets, fittings costs about $20 with shipping. Does this sound like a reasonable course? This is a $160 compressor when I bought it new.
Any feedback would be appreciated.
Thanks,
Eric

Eric, you are well into it now, and I'd suggest that your gasket guess might be a good one, or it could be the valves. It were my compressor, I would be changing out the valve plates and putting in a new gasket kit.

Rigid OL50135 leaks air at connection

by Norm
(Tahuya, WA)

The air leak is at the connection on the right and behind the trim panel. I cannot figure out how to remove this hose connection and troubleshoot it. The connection to the left outlet is fine.

Norm, I don't have the unit so can't tinker with getting the trim panel off for you which is what you will have to do to tighten or repair the connection.

Maybe someone who reads this post has dealt with the same issue before and can post their findings?

Or, these guys might help:

Rigid of45150 has no air coming out of the hose

by alfonso
(Pensacola FL)

I have a rigid of45150 dual tank compressor, no air coming out of the hose

Starts and appears to be working fine but no air coming out the hose,and only builds pressure on one side, could it be the regulator? any suggestions would be appreciated thank you.

Rigid compressor has low outlet pressure

by Steve
(Oshkosh, WI)

My rigid twin stack builds pressure. It also shows adequate pressure at the outlet until I attach the hose. Then it drops significantly and very little air will discharge. When I remove the hose, outlet pressure shoots right back up to normal. Any suggestions?

Steve, lets talk a bit about pressure and flow. They are two different things.

If you have 120 PSI in a small air compressor tank, and open a 1/4" hose from the tank, that pressure will drop in seconds as the flow of air out of the tank exceeds the capacity of the air compressor to keep the tank full.

What is it you are trying to run?

Although it is possible that your discharge coupling or your air hose, or your air tool may be imparting a restriction to the air flow from the compressor, my first guess is that you are trying to run a high demand air tool with a too small compressor.

If I'm wrong, post a reply here, and give me details about what you are trying to do with the compressed air supply.

Cheers,

Bill
