Greenheck Expands Plenum Fan Line with Model APD

Greenheck’s new Model APD plenum fan features a direct drive fan with the wheel connected to the motor shaft. With no fan shaft bearings or belts to maintain, Model APD eliminates the cost and maintenance associated with traditional belt drive plenum fans. Ideal for array applications in air handler retrofits or when pressurizing a plenum room, Model APD’s compact size and smaller footprint make installations easy. When combined with a VFD, air volumes can easily be matched to changing building requirements or overcome increased pressures from dirty filters. Model APD offers an operating range up to 18,000 cfm and external static pressure up to 10 in. wg. Constructed from a formed and bolted galvanized steel frame with a welded and coated 7-bladed, backward-curved steel wheel, Model APD is an excellent option as a stand-alone single fan or in parallel fan array applications.

Greenheck is the worldwide leader in manufacturing and distributing air movement, conditioning and control equipment.
