How many CFM from NCT-501-1 ?

I would like to know how much air (cfm) my NCT-501-1 will produce?

______________
I would like to help, but since this model doesn't appear to be current and I can find no information on line I don't have a specific answer.

If, however, you look at the CFM and flow related pages on this site, you will find info that will give you a good idea based on your air compressor's motor HP.

Cheers,

Bill

Devilbiss Charge Air Pro making tinny sound?

I'm beginning the trouble shooting process on a Lowes-sold Devilbiss compressor setup (Charge Air Pro). It's been a good one, lasting about 20 years.

It still pumps up fast, but now has an annoying "tinny" rattle that begins at about 50 pounds.

It sounds like tin flakes bouncing off the inside of the tank?

Although I try to keep water drained, I suspected that it was the tank rusting inside. But nothing ever came out of the drain plug except a little water.

I've ordered a new check valve and am hoping that solves it, although the old one appeared OK. I'll include a photo although one of the lines is temporarily removed from the unit.

Any suggestions will be appreciated. Thanks

John, with the compressor problem starting at 50 PSI suggests to me that it may be a pressure valve problem developing.

That is refuted by your comment that it still pumps up fast, though that is subjective. You might want to time a refill now and have that as a base line for a time-to-fill test later on. If the time-to-fill becomes longer, that will suggest a mechanical pump issue.

A "tinny" noise is hard to mentally replicate John.

Any other comments or suggestions for John?

Thanks,

Bill

Devilbiss PFACS2X4 will not get above 85psi?

Have a Devilbiss PFACS2X4 pancake compressor. Just replaced brushes on motor and now will pump up to about 85 psi but, no higher?

Rick, assuming that there is no evidence of failure on the electric motor of your Devilbiss PFACS2X4 air compressor, the two issues may not be connected at all.

It may only be bad luck that the repair of one compressor problem was resolved only to have another surface.

When you pull off the intake filter - assuming this model has one - can you feel air being pulled into the intake filter while the compressor is running? Any air huffing back out? If air is huffing out, that likely indicates a back valve.

The problem with some of these micro-compressors is that they really only have a piston with a hole in the end that pulls in air. If this is yours, then your problem is likely valve related, and you will need to disassemble the pump.

If you do that, you might as well have a gasket kit on hand if one is available, because a blown gasket (lets go at 85 PSI in your case) is the second most likely thing.

What did you find?

Cheers,

Bill
