PS – mechanical differential pressure switch for air

The PS series mechanical differential pressure switches offer a cost effective solution for filter, fan and duct pressure monitoring in building automation systems in the HVAC/R industry.

PS series products offer field selectable switching point adjustment.

Applications

  • monitoring filters and fans
  • monitoring vacuum and overpressure in air ducts
  • controlling defrosting functions
