AUX AIR PRESSURE

[Danss]

What kind of adjustable pressure air regulator can you find that lets you adjust to around 40 on to 80 off?

Dan,

You'll probably find most pressure switches to turn on 20-25 PSI below the turn off pressure. Do you have a special need to let the pressure drop 40 PSI? If you can't find one, you can install 2. A bit ugly, but it can be wired to work.

I've seen Regulators on buses that you can adjust the parameters like that but I have to agree with Gill it's kind of unnecessary.

There's two little set screws in them versus a 3/16 nut squeezing or releasing the tension on a spring which is how the most of them are.

[Gil_J]

BTW, don't buy a pressure switch without an unloader valve, which most if not all air compressor pressure switches have.

Cannot find one that is adjustable because I need 12v

[Gil_J]

Dan don't worry about the voltage. The ones rated for 120/240V will work fine. The current rating is the important spec.
