The Model AK100D dual-speed Quiet Series exhaust fan provides cost-effective, energy-efficient ventilation. The American Society of Heating, Refrigerating, and Air-Conditioning Engineers Standard 62.2 ventilation can be accomplished by using the Home Ventilating Institute (HVI)-certified low speed of 50 cfm at 0.5 sones for continuous ventilation of the home and the HVI-certified high speed of 100 cfm at 1.5 sones for times when the room is occupied and in need of additional ventilation power. An electronically balanced centrifugal blower wheel ensures maximum ventilation with minimum sound. The low sound level and energy-efficient operation of the fan allows the unit to be both Energy Star® qualified and California Title 24 compliant. The model AK100D features a low-profile grille design that almost disappears into the ceiling, along with a metal housing and duct collar. A spring-loaded, back draft damper prevents drafts from entering back into the room through the ducting. The unit is ETL-listed for installation over a tub or shower on a GFCI circuit. It is available in contractor packs of four units.
