Pressure Switches

A pressure switch automatically starts and stops your air compressor based on the preset pressure levels in the air receiver. This helps maintain consistent air pressure while protecting the compressor from running unnecessarily or over-pressurising the system.

Common signs of a faulty pressure switch include the compressor not starting, failing to switch off at the correct pressure, cycling on and off too frequently, or inconsistent air pressure. If you notice any of these issues, replacing the pressure switch can help restore reliable operation.

Replacing a pressure switch is possible, but it should only be done by someone familiar with compressed air systems and electrical connections. Choosing the wrong pressure settings or wiring the switch incorrectly can affect performance and safety. If you’re unsure, Airpower can help you select the correct replacement.

The correct pressure switch depends on your compressor’s cut-in and cut-out pressures, motor voltage, current rating, and connection size. Matching these specifications ensures safe operation and reliable performance. If you need assistance, Airpower can recommend the right pressure switch for your compressor.

Pressure switches generally require very little maintenance, but they should be inspected during routine compressor servicing to ensure they are operating correctly. Regular checks can identify worn contacts, damaged wiring, or incorrect pressure settings before they cause unexpected downtime.
