Air King introduces AK100D dual-speed Quiet Series exhaust fan for “cost-effective, energy-efficient” ventilation. According to Air King, ASHRAE 62.2 ventilation can be accomplished by using the HVI-certified low speed of 50 CFM at 0.5 sones (barely audible) for continuous ventilation of the home. The fan features a low profile grill design which it describes as “almost disappearing” 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.
