Greenheck Introduces QEID Upblast Fan

August 26, 2022

Greenheck’s QEID direct drive mixed flow fan is now available in a roof-mounted exhaust or upblast configuration ideal for discharging clean air or fume exhaust up and away from a building. The QEID 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, and 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, while a windband protects the dampers from debris and keeps the damper blades closed when not in operation.

The QEID Upblast fan is also UL/cUL Listed for Electrical (UL/cUL-705) and Power Ventilators for Smoke Control and can be used for emergency smoke exhaust applications.
