what should the recovery time be on a Craftsman 20 Gallon Portable Vertical Air Compressor

it takes forever for it to refill to full pressureā€¦and today, I watched the dial and it did not move at all while the motor was running. I unplugged it to listen, and did not hear any leaks.


Should it take a long time? How can it be running and the pressure not increase?

You are not alone. Many, many questions here about why compressors run and will not build pressure past a certain pressure level.

The recovery time of your air compressor should be measure in minutes, at most.

There are a number of reasons why an air compressor will run and not build pressure.

Most (all?) of them are linked from the Compressor Troubleshooting page, Will Not Build Pressure.

Why not check a few things out based on that page, and then post a comment here if you are still stymied?

Cheers,

Bill

Old Craftsman paint sprayer compressor spewing oil and water

by Robert
(Pickerington, Ohio, USA)

I have an old Craftsman paint sprayer compressor mdl. 106.153200.

When I plug it in water and air spew out the valve on the bottom of the tank. Should I be concerned about this? I rarely use this compressor, but I want to be sure it's safe.

Robert, what you are describing is what typically happens when a tank drain is left open. And, from the sounds of it, it hasn't been drained often enough.

If you close the drain valve, then, assuming the rest of the compressor works, and it sounds like it does, then pressure will build in the tank to the cut out pressure level.

As soon as you get a full charge of air in the compressor tank, open that drain valve again, and allow all the build up of water and oil to drain out. It will be messy, so open the drain valve over a piece of cardboard or some such.

Look on the site map for DRAIN THE TANK for more info.

By the way, a large amount of oil in the tank suggests that your piston seals may need work.

Cheers,

Bill

My Craftsman model 919167242 stopped turning on

by Danny
(Texas)

My Craftsman model 919167242 15 gal compressor was working fine, I was running a brad nailer and noticed it had not turned on for awhile. When I chaecked it out, it was totaly dead, will not turn on at all. Pressure switch?

Danny, if you pop over to the TROUBLESHOOTING page, you will see a link to "will not start". Have a read of these issues and checks, and then post a comment here letting me know what you found on your air compressor.

We'll figure it out. You just need to do a bit of homework to tell me what all the symptoms are, and ensure that the basics are covered.

Cheers,

Bill
