Air King (West Chester, PA) has recently added humidity sensing exhaust fans to its extensive line of ventilation fans, says the company. The new humidity sensing exhaust fans are available in single and dual speed models, with a maximum speed of 80 or 130 CFM. The ultra low sound level and energy efficient operation of the humidity sensing exhaust fans make them ideal for ASHRAE 62.2. Once installed, the exhaust fan turns on automatically when the humidity level in the room reaches the preset percentage, then will automatically shut off when the humidity level falls below the preset percentage.
