Available in roof-mounted exhaust or upblast configurations.

Greenheck’s QEID direct drive mixed flow fan is available in a roof-mounted exhaust or upblast configuration to discharge clean air or fume exhaust up and away from a building. The upblast’s mixed flow wheel offers higher efficiency operation than a belt drive fan and requires less maintenance by eliminating belts, pulleys and fan-shaft bearings.

A factory-programmed VFD enables easy adjustment and control. A fully welded heavy-gauge curb cap eliminates leaks and allows for quick mounting to a roof curb. Butterfly dampers provide backflow protection and prevent rain penetration. The windband protects the dampers from debris and keeps the blades closed when not in operation.
