compressor controls - pressure switches

by Joseph Rogers
(Leavenworth Kansas)

I have 2 champ. uprights that are set up to run tandem.
Many of our tools are cordless now and we don't need that much capacity anymore.
They are set up so #one cuts in @ 140 psi and #2 @ 100 psi.
I need to adjust the cut in on #2 so it also cuts in @ 140 psi
so we can run 1 pump at a time but let it use both tanks.
I read a description of the pressure sw. in another mssg.
but the only advice is always "don't change the adjustment".
I'd like to be able to switch daily from one pump to the other
so the # 1 pump isn't the only one doing all the work.
If we get a spurt where we're consuming alot of cfm (rotary
tools) by the time the # 2 pump starts the pressure out at the
tool has dropped enough to affect it's performance.

Joseph, there are two adjusting nuts inside typical pressure switches. Turning one adjusts the cut in, turning the other the cut out.

Follow the links from the Pressure Switch section on the site map page for more detailed info.
