About This Product
This duct air pressure switch is designed to sense pressure changes within the duct system, specifically between the main blower and a duct booster fan. When the main blower activates, the resulting pressure rise triggers the switch, automatically powering the duct booster fan. It operates on 120 volts and supports up to 15 amps. The switch activates at a pressure increase of +0.05° 0.02 inches water column (W.C.).
Highlights
- Detects duct air pressure to control booster fan operation
- Activates duct booster fans using positive pressure from the main air handler blower
- Supports fans rated up to 15 amps at 120 volts
- Suitable for year-round use with both heating and cooling systems
