BUILT TO HANDLE DUAL COMPRESSORS

Wiring up dual air compressors just got easier. Our HornBlasters 110-150 PSI Weatherproof Pressure Switch now comes with dual 40A relays built in, letting you run two air compressors without the hassle of separate relays or complex wiring.

Everything is wired and ready to go—two power wires, two grounds, two wires for your air compressors, and a key-on power wire. All wires are clearly labeled to make your install fast and straightforward.

Encased in a weatherproof coating, this pressure switch is made to handle the elements. It kicks on your compressors when tank pressure drops below 110 PSI and shuts them off at 150 PSI. Perfect for dual setups needing reliable and accurate performance in any condition.
