• Activates an electronic air cleaner, a humidifier, or other equipment in response to airflow from the system fan
• Mounted in the return air duct where the sail will be in the direct path of an unrestricted air stream
• 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
• Simplified installations with multi-speed fans, inaccessible air handlers, fan motors with voltage or phase different from controlled equipment, eliminated wiring to system fan
• Top and bottom conduit knockouts for wiring convenience
• Low air velocity switch operation makes at 250 fpm and breaks at 75 fpm
• 10" insertion
• 26.2 sq-inch area sail
