  • All air switches come in a contractor kit that includes the hardware, replacement hose and an adjustment tool for easy installation and calibration
  • These switches include features such as factory calibrated and factory fixed set points, NEMA rated housings, manual resets and gold contacts
  • Select air pressure sensing switches are practically insensitive to temperature change with an operating range of -40 to 190 deg F
  • Conditioned air filters that accumulate particulate matter used to sense the differential pressure or airflow drop across the filter
  • Defrost cycle is initiated by sensing differential pressure or airflow drop across the refrigeration coils when they ice
  • On gas fired units, the switch senses draft down from the blower; switch actuation allows ignition start-up or system shutdown upon insufficient draft
  • On air-supported structures and enclosures, sensing switches ensure proper inflation or internal pressure switch actuation controls the blower to maintain pressure
  • Exhaust fans and fume hoods employ switches to sense draft down from the exhaust fan switch actuation signals condition upon fan failure of insufficient draft
  • Vertical mounting location
