Company: Greenheck Fan Corp.

Product: Model APD

Description: This plenum fan features a direct-drive fan with the wheel connected to the motor shaft. With no fan shaft bearings or belts to maintain, it is ideal for array applications in air-handler retrofits or when pressurizing a plenum room. When combined with a variable frequency drive (VFD), air volumes can easily be matched to changing building requirements or overcome increased pressures from dirty filters. It offers an operating range up to 18,000 cfm. Constructed from a formed and bolted galvanized steel frame with a welded and coated seven-bladed, backward-curved steel wheel, it’s an option as a stand-alone single fan or in parallel fan array applications.
