Frequently Asked Questions
Q: What compressors is this air compressor pressure switch compatible with?
A: This 90–120 PSI pressure switch is designed as an aftermarket OEM replacement and is compatible with a wide range of miniature and standard air compressors that operate at 220V. Always verify thread diameter (approx. 11.5 mm) and pressure range before installing to ensure a proper fit.
Q: How does the automatic pressure switch work?
A: The pressure switch monitors the air pressure inside the compressor's tank. When pressure drops below the set minimum (90 PSI), it automatically turns the compressor on to rebuild pressure. When the tank reaches the maximum set point (120 PSI), it shuts the compressor off — maintaining a consistent pressure range automatically.
Q: Is this switch easy to install on my existing compressor?
A: Yes! This control valve is designed for straightforward installation. It features a standard thread diameter on all 4 female inlet ports and includes a simple red ON/OFF knob, making it a cost-effective DIY repair that can restore your compressor to full working order without needing a full replacement.
