Diaphragm Vacuum Switch

Diaphragm Vacuum Switch

Presair’s diaphragm vacuum switch has an user adjustable set-point and small switching differential. This diaphragm operated vacuum switch can reach up to 300 inches of water gauge.

Presair’s adjustable vacuum switch contains a pressure sensitive diaphram which operates a non latching snap action microswitch. The switch can be used to operate an electrical circuit when the system pressure rises or falls through an operator-determined pressure set point between 0.25 inches of water to 300 inches of water.
