If you need to make further adjustments, unplug the compressor before doing so to avoid electrical shock. As a result, the power flows back to the motor and the motor starts again to compress more air. The safety relief valve is set to provide protection of the system from a situation where the pressure in the vessel increases beyond the specified design pressure. Adjustment is the same: unplug the compressor and turn the set screw one rotation inward to get a higher pressure level and is turned counter-clockwise to get a lower pressure level. When you turn the adjustment screw counter-clockwise, the cutout pressure drops while the cut-in pressure drops by a corresponding amount.

The Air compressor pressure switch is an important part of electric air compressors. It has a pressure gauge for measuring output. 4. The air compressor pressure switch measures the pressure inside your air tank and shuts off your compressor when it reaches the air pressure you need. With this information, you can determine whether it is necessary to adjust the setting. With an air compressor, however, the switch also triggers the air compressor to begin pressurizing. Diagnose a cranky switch by rapping on it with a screwdriver handle. The point when the air compressor starts is referred to as the cut-in pressure point. This means that you can adjust it so that your compressor creates more pressure in the tank, but in doing so, you’ll also raise the threshold at which the compressor will kick on. Maintain a minimum of 20-PSI pressure range between cut-in and cut-out. The air compressor is built with two pressure set points. Dialing up the pressure switch can help you “cheat” that little extra power from your compressor. Quick View. As the tank fills with water, the bladder/diaphragm expands, creating more air pressure inside the tank. This range is the difference of cut out and cut in pressure or the pressure band as I have said earlier. The pressure switch is your best line of defense against any possible ruptures as it prevents the tank from getting over-pressurized.
