Pressure Switch, 100/135 PSI #01AB5F

Old Part Numbers: CW209000AJ, CW208800AJ

Campbell Hausfeld CW209000AV pressure switch. For models with a line cord and plugs.

Replace the pressure switch if the compressor no longer cuts in or cuts out at the designated pressure (PSI), if the unit doesn't turn on or off, or if there is an obvious air leak from the contacts or manifold.

If the small unloader (bleeder) valve on or under your switch leaks constantly AFTER the unit shuts off, don't replace this part, replace the in-tank check valve. Most pressure switches have a bleeder valve which has a 1/4" plastic or copper line routing to it.

Specifications

• 100 PSI cut-on
• 135 PSI cut-off
• 90° unloader valve
• 4-port manifold (1/4" FPT)

Extra Details

If the 90-degree unloader valve leaks constantly (where the 1/4" bleeder line installs) after the compressor shuts off, you have a defective tank. Check valve; your pressure switch is okay.
