Variable Vacuum Switch

Presair’s variable vacuum switch converts a negative pressure signal to an electrical output. In response to a change in negative pressure, movement of a diaphragm opens or closes an electrical circuit based on a factory set point. Presair’s vacuum switches are offered both field adjustable or factory set. The vacuum switch is ideal for original equipment manufacturers and instrument makes to meet the exacting standards for a low cost solution. Vacuum switches can sense a pressure range from 0.5-300 inches of water.

Spas, whirlpools, jetted baths and hot tubs incorporate Presair’s high quality, UL approved switches and controls. Other important applications are medical equipment, plumbing and HVAC equipment and products for the home.
