Value Added Features Quality Assurance Test Before shipment, all Greenheck mixed flow fans are tested at the design speed after final assembly. QEI-L fans are checked for amp draw and the levels are recorded. QEI-I/II and QEID fans are subjected to a complete vibration analysis. The maximum allowable vibration on a QEI-I/II at the fan bearings is 0.15 in/sec. peak velocity for the specified RPM. QEID maximum vibration is 0.08 in/sec. peak velocity on the fan housing for the specified RPM. A

Inlet and Outlet Sound Power Levels All Greenheck mixed flow fans have AMCA licensed sound power levels for both the fan inlet and outlet. Application and installation determines which sound power reading (inlet, outlet, or both) is critical. The differences between the generated sound from the inlet and outlet are important and noticeable. AMCA licensed inlet and outlet sound power data provides complete sound information to select a fan based on the acoustical requirements. For additional

Design & Performance Mixed Flow: Axial/Centrifugal Hybrid Centrifugal A mixed flow wheel is a hybrid between an axial propeller and a centrifugal wheel. The result is a design that combines the best axial Mixed Flow and centrifugal properties: highly efficient air movement, increased pressure capabilities, extremely low sound levels, and a steep fan Axial performance curve. To further enhance the fan’s performance, straightening vanes are incorporated in the housing. These serve to convert

Wheel Characteristics Belt Drive: Fan Class Class I and II fans have different wheel designs with different performance characteristics. Class I mixed flow wheels are optimized for performances involving low pressures and high volumes. Class II wheels are designed for a steeper fan curve with higher pressure capabilities. This is illustrated in the graph with the two different class wheels plotted at identical fan RPMs. When selecting a mixed flow fan, it cannot be assumed that moving into a C

Optional Features Sure-Aire™ The Sure-Aire™ flow monitoring system measures fan flow within a 3% accuracy. Unlike traditional flow probes mounted in the fan venturi that create a system effect hindering fan performance, Sure-Aire™ does not interfere with airflow and will not impact the fan’s air or sound performance. This option is available on all mixed flow fan models and ships completely assembled from our factory. An electronics package with pressure transmitter and digital read out
