SpaShopper offers this PresAir vacuum-sensing safety switch designed for suction protection systems commonly installed in Cal Spa models and other hot tub brands.

This safety component functions as a normally open switch that activates when detecting vacuum conditions. Upon sensing sufficient vacuum pressure, the switch closes its circuit and immediately shuts down the control system. This critical safety mechanism protects bathers by detecting blockage conditions at suction fittings and automatically powering down the system to prevent entrapment hazards.

Technical Specifications:
Switch Type: Vacuum Switch
Vacuum Switch Brand: PresAir
Thread Material: Plastic
Amperage: 25 Amp
Action: SPDT
Plumbing Size: 1/8" MPT

The adjustable range of 135-250" water column allows for precise calibration to your spa's specific requirements, ensuring optimal safety response times while preventing false triggering during normal operation.
