- As air is used, pressure drops.
- Once the pressure falls below a certain point, the switch closes.
- This restart signal turns the compressor back on.
This cycle repeats, maintaining optimal pressure levels. The pressure switch acts like a gatekeeper for air flow.
Pressure Setting And Adjustment
Adjusting the pressure setting on a pressure switch is crucial for performance. Here are steps to do so:
- Turn off the air compressor.
- Locate the pressure switch. It’s usually near the motor.
- Find the adjustment screws. There are typically two:
- Cut-in Pressure: The pressure at which the compressor starts.
- Cut-out Pressure: The pressure at which the compressor stops.
- Use a screwdriver to adjust the screws.
- Turn clockwise to increase pressure.
- Turn counterclockwise to decrease pressure.
- Test the compressor after adjustments.
Always consult the manufacturer’s guidelines before making changes. Proper adjustments lead to better efficiency and lifespan of your compressor.
