Provides significant energy savings by inexpensively distributing make-up air strategically and comfortably throughout a building.

Air Make-Up Jet Fan systems utilize a propeller fan in conjunction with a modulating face and by-pass control dampers to mix cold outside air with warm inside air, which results in  inexpensive, tempered make-up air that can be distributed evenly throughout the work space, providing greater comfort and energy savings.
