This belt drive, roof mount, filtered reversing fan moves air in both exhaust and supply modes. The fan features cast aluminum airfoil blade propellers and an aluminum or steel fabra hood-style housing. 2,900 to 58,000 cfm Up to 0.5 in. wg.
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 buildi
Model KSQ is a direct drive, filtered supply fan designed to provide non-tempered make-up air in commercial and industrial applications where efficiency, sound and cost are a major focus. The KSQ is ideal for cost sensitive applications where heating and cooling are not required. Units feature a mi
The Variable Geometry Nozzle (VGN) automatically adjusts to maintain the specified discharge velocity as lab airflow varies. This safely prevents re-entrainment in the make-up air unit and provides energy savings through lower fan speeds in reduced lab flow situations without introducing bypass air
Stand-alone VFDs supplied with Vektor fans. Sized and factory programmed with supplied motor information along with maximum speed per the supplied motor and fan construction. System control signal and operation of the fan speed, as well as other systems components such as isolation and bypass damper
The Vektor System Control (VSC) package offers a pre-engineered, stand-alone controller for laboratory exhaust fans. Components and sequences of operation easily integrate Greenheck Vektor exhaust fans into a variable or constant volume lab exhaust system. Duct pressure modulation, fan speed, redund
