Spa Vacuum Switch

Presair offers a full line of vacuum switches that work as a safety suction switch, which keeps your pumps and heater working in your spa. Commonly found in the Cal Spas, the vacuum switch continues to provide operation to the heater and pump. If a faulty vacuum switch is used, the heater and pump will shut down to prevent problems.

Presair mechanical vacuum switches make electrical contact when a certain set vacuum has been reached on its input.

Our mechanical vacuum switches are available in multiple styles including adjustable vacuum switches or fixed set point vacuum.

By providing on/off switching from a pneumatic source, Presair vacuum switches deliver critical benefits:

  • Safe and Convenient: Remote operation with complete electrical isolation. UL Recognized.
  • Economical: Costs less than conventional controls
  • Accurate: Highly stable with good repeat accuracy. All switches are 100% tested at high and low settings and at proof vacuum.
  • Reliable: Minimal moisture absorption and maximal dimensional stability.
