Explosion Proof Vacuum Switch

Our Explosion Proof Vacuum Switch products makes these switches ideal for chemical process and other hazardous environments. Presair air, pressure and vacuum switches are also waterproof and shockproof.

Presair air switches are a safer solution compared to conventional controls. The Presair system uses an air bellow actuator joined by tubing to an air switch contained within the equipment to be switched. Pushing the actuator creates enough pressure to operate the air switch which safely controls the equipment. There is complete electrical isolation with no voltage – low or high – to worry about at the point of actuation, making it safe to use in explosive environments!
