how to adjust a air compressor pressure switch

An air compressor pressure switch is a safety measure that can help safeguard a compressor from potential damage. If the pressure levels in the compressor become excessive, the switch will be triggered to switch off power to the unit. This action ensures that the compressor is not overburdened and can avoid being damaged as a consequence.

Adjusting the pressure switch on your air compressor can be tricky, but there are a few easy steps to follow in order to do it right and remain secure. Here they are!

1. To begin with, familiarize yourself with the pressure gauge on the compressor and notice the current pressure displayed in the system. If you detect that it exceeds a safe level, then you must decrease the power to the compressor and release some of the accumulated pressure before you continue.

To find the pressure switch, you’ll need to look on the side of the compressor – it’s usually located there.

The pressure switch is fitted with a knurled knob or screw, which can be twisted as required. To increase the amount of pressure, turn the knob clockwise. To lower the pressure, turn the knob counterclockwise.

Once the pressure setting has been tweaked, switch on the compressor and take a look at the pressure gauge. If it’s still not where you’d like it to be, continue adjusting the pressure and confirming the readings until the ideal level is achieved.

When the pressure in the system falls below the standard, you’ll have to shut off the compressor’s power source. Subsequently, add air into the system until it centers back on the prescribed amount of pressure. Now, you can resume power and ensure the by having a further glimpse at the pressure gauge.

With the proper pressure gauge reading, it is evident that the pressure switch was successfully adjusted.
