Question about Heating & Cooling

Low psi while running continuously.

I have a Craftsman 3-gallon air compressor, model #921.153101. It is 20 months old and only used occasionally. It will only approach 30-35 psi and runs continuously.

I am assuming this is an oil less compressor as I have never seen a crapsman compressor that is not
you need to feel around the head and see if there is air leaking anywhere usually around the tube that goes to the tank or the pressure relief valve

I have an old craftsman impact gun model number 875-188992. what size compressor do I need for taking off lug nuts/automotive work?

The two most important specs are CFM at 90 psi (that's how fast the compressor can compress more air when the tank starts to run low) and how big the tank is. Virtually any compressor that has a top pressure rating 20 psi higher than you need for your tool (which is usually about 90 psi) and that has a tank of a couple of gallons will work. But the smaller the tank, the shorter time you can operate the tool before the compressor has to kick in. And the lower the CFM at 90, the longer you will have to wait for the tank to come up to pressure again so you can operate the tool at full pressure. If this is for occasional use and you aren't in a hurry, you don't need much of a compressor at all. If you want to operate continuously, then you should get something with a CFM at 90 psi that is higher than your tool's CFM consumption. Keep in mind that impact wrenches don't operate continuously like paint sprayers do. Good luck. Vote if you found this helpful. Al K

My compressor will not go over 20 psi i have a craftsman 921 4 gal 125 psi compressor and it will not build past 20 psi i do not know how to get to the pistons and stuff what do i do?

The problem with compressors not building pressure is usually a bad pressure switch or bad regulator. Does the motor shut off at 20psi or does it continue running and not build pressure? If the motor continues to run with no increase in pressure, the you should go over the machine looking for air leaks from your regulator back all the way to the motor. Any air leak while the compressor is running can cause the pressure to "peak" way before the intended shutoff that it is regulated to.
