Frequently Asked Questions
Q: What air compressor types is this pressure switch compatible with?
A: This 1/4-port manifold air compressor pressure switch is compatible with most standard single-phase air compressors operating at 220V. Its four-port manifold design fits a wide range of compressor brands and models. Always verify your compressor's voltage and pressure ratings before installation.
Q: What is the maximum pressure this switch can handle?
A: This automatic pressure switch is rated for a maximum working pressure range of 90–120 PSI (0.6–0.8 MPa / 6–8 BAR), with stable operation up to 125 PSI. It is not recommended for use beyond this pressure range.
Q: Is this pressure switch easy to install?
A: Yes. The standard 1/4-port manifold configuration is designed for straightforward installation on most air compressor setups. Basic hand tools are typically all that's needed. If you're unsure about electrical wiring, consult a qualified technician to ensure safe installation.
Q: Can this switch help reduce my electricity usage?
A: Absolutely. By automatically shutting off your compressor motor when the set pressure is reached and restarting it only when pressure drops, the switch prevents the motor from running unnecessarily — contributing to lower energy consumption over time.
