Can you modify the shut off and kick back PSI on a compressor?

[plain garage]

I have a small IR compressor, it fills to 135psi then stops and kicks back on below 100psi. For most tools at 90psi, this is fine, but occasionally I need the working psi to be ~110psi. Given it has a 100% duty cycle motor, the question is can I change the shut off and kick back psi settings on the compressor to say 110/145? If so, how?

pressure switches come in many flavors.

most have a screw adjustment under the cover for this but depending on the size of your compressor it might be hard pressed to keep up with 110 psi. I'd be supprized if anything under 5hp 220 could keep up with 90psi.

Most single stage compressors are pushing it to make 150 psi, and some will not do it. To crank up the pressure is not as simple as just turning the screw, you also have to know if the compressor will make the pressure without burning out. A few more details on the compressor will allow us to help a bit more. HP and or a model number. Better yet a link to the one you have.

Most of the standard pressure switches have a fixed deadband (range between on and off setpoints) and adjusting the screw just moves this range up or down (so for example 90-120psi on/off could get dialed up to 120-150psi). There are plenty of more sophisticated control setups used on industrial equipment, but of course those will cost more.

Does your compressor have enough flow that it can keep up with whatever tool you want to run on a continuous basis? If not, your pressure will drop below 110psi regardless of the pressure switch setpoints.

Have you considered using a pressure regulator?

The right answer, this being a garage/tool forum and all, is a much larger 2-stage compressor with a regulator set at 110psi. Then you're at 110 all day long, no higher and no lower. And you'll wonder how you ever got by on whatever girly-man compressor you are using now

I have the 2hp 20gallon garage mate compressor. Its a baby compared to most but it gets the basic jobs done. I'm eyeing a low end tire changer that uses 110psi @5cfm. Since the air is only used in spurts for the bead breaker, clamp claws and turn table and the machine has its own charge tank, I figured if I kept the psi charged up, I'd be OK?

Am I being unrealistic?
