The Presair air switching system is similar to Hergair by using 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.
Presair air switches deliver complete electrical isolation with zero voltage at the point of actuation. The air switching system connects the air switch to an air bellow using air tubing. When the air bellow is pressed, it sends a pulse of air through the tubing actuating the air switch.
Presair air switches cost is comparable or lower than conventional controls to meet the needs of the original equipment manufacturer.
Presair’s air switching system is commonly used in pool and spa application, home appliances, medical applications, industrial applications, and many others!
