About This Product
Use this sail switch to activate a humidifier or an electronic air cleaner when you have a variable speed air handler or a variable speed furnace (not needed if you have a Goodman variable speed furnace). This sail switch is mounted in the return air duct where the sail will be in the direct path of an unrestricted air stream.
Features
Simplified installations with multi-speed fans, in- accessible air handlers, fan motors with voltage or phase different from controlled equipment; eliminated wiring to system fan.
Polyester film sail mounted on a micro switch snap switch.
Removable spring counterbalances sail to allow mounting in either vertical (up or down) or horizontal air flow.
Top and bottom conduit knockouts for wiring convenience
Low air velocity switch operation makes at 250 fpm and breaks at 75 fpm.
