Review on High-Quality Square Schneider Electric 9013FHG12J52M1X Air Compressor for Efficient Performance by Drew Gengler

Easy replacement for an older 1.5hp Rolair two tank electric wheelbarrow compressor. It's set at 125psi for cutoff, but you can set it higher. I set mine to cut off at 135psi. The notch is set about 25psi less, so my notch is about 110psi. I don't know the max psi cutoff but it says this switch can't be used above 220psi so I'm guessing it's above 135psi. Range adjustment is done with a single screw. Remove a nut retaining cap and tighten the 5/16" bolt to increase the shutoff pressure. Instructions included.
