Product Description
The King MAU Make-Up Air Unit is a plenum rated unit, designed to “make up” the air in your interior space that has been removed due to process exhaust fans. The building ventilation and the make-up air system work together to ensure the building pressure is maintained, while eliminating temperature fluctuations and a number of air quality issues. MAU preheats the incoming fresh air at the lowest cost, thus continuously providing comfortable ventilation throughout the building.
Featuring an energy efficient ECM motor, the MAU combines a fan driven fully modulating electric heating unit with a fresh air relay logic control circuit providing an extremely versatile all-in-one packaged unit.
The MAU is approved for use in concealed areas of buildings such as an area between a finished ceiling and drop ceiling. It is designed to work with HVAC equipment to provide indoor air quality into a return side or supply side of the ductwork system or alternatively directly into the building space.
