OVERVIEW

QEID-Upblast

Model QEID Upblast is a direct drive mixed flow fan standard with curb cap for quick mounting to a roof curb, butterfly dampers to prevent rain penetration and windband to keep the damper blades closed when not in operation. The QEID Upblast effectively removes clean air out and away from the building. It has higher efficiency operation than a belt drive fan and less maintenance by elimating belts, pulleys and fan shaft bearings. Available with factory programmed VFD for easy adjustment and control.
