Description

The PS1503 Duct Airstat switch is designed to sense the positive pressure increase in a supply plenum or duct when an air handler or furnace blower is in operation. The increased duct pressure expands a diaphragm which in turn mechanically closes the
normally open electrical switch contacts to activate accessories in tandem with the central blower. Typical accessory devices activated include duct booster fans, furnace mounted humidifiers, UV air purification units and duct heaters.
