Quiet & Efficient, Inline Mixed Flow Fans Model QEI-L – Belt Drive Mixed flow inline fans can be used for supply, exhaust, or return air installations. Our patented design excels in commercial applications where low sound is critical. In addition, Greenheck’s mixed flow fans are more efficient than comparably sized tubular centrifugal and vane axial fans, thus reducing the required motor horsepower and lowering operating costs.

Standard Construction Housing Slip-Fit Duct Connection (QEI-I/II & QEID) Tubular housings are constructed of welded steel to eliminate air leakage. Integral straightening vanes are constructed from steel and welded into place. Inlets and outlets are designed with extended collars for slip-fit duct connections as standard. QEI-L is flanged as standard. Companion flanges can be ordered for slip fit connections.
PAGE 4
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.
PAGE 5
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.

Design & Performance Mixed Flow: Axial/Centrifugal Hybrid Centrifugal Static Pressure 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 and centrifugal properties: highly efficient air movement, increased pressure capabilities, extremely low sound levels, and a steep fan performance curve. To further enhance the fan’s performance, straightening vanes are incorporated in the housing.
PAGE 7
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.
PAGE 8
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.

Optional Two-coat Paint System In 1972, Greenheck took the lead as the first commercial and industrial fan manufacturer to introduce electrostatic powder coatings. Today, Greenheck continues to lead by being the first to offer a superior zinc-rich powder basecoat and powder coating finish. This zinc-rich basecoat technology is used extensively outside the HVAC industry to protect bridge beams, automotive components and other heavy-gauge steel products.

Certifications & Listings Tau Bot psi 7880 7090 6300 5510 4720 3930 3140 2350 1560 770 -20 Y Z Seismic Certification X The International Building Code (IBC) has been adopted at the state and local level throughout the United States. With the adoption of this code, comes the introduction of standards intended to improve the performance and design of non-structural systems subject to seismic events.

Belt Drive Mounting Configurations QEI-I/II Sizes 9-27 and all QEI-L Universal Mounting Optional Mounting Rails Fig. 1 Fig. 2 QEI-I/II models sizes 9-27 and all QEI-L models can be mounted horizontally or vertically. For ease of installation, eight mounting brackets are welded on each fan. These eight brackets along with standard mounting supports provide for Greenheck’s Universal Mounting System. Motor positions are viewed from the discharge end. Fig.

Roof Upblast & Spark Resistant Construction Roof Upblast Models QEI-I/II sizes 9 through 54 and model QEID sizes 12 through 54, are available in roof upblast configuration. The roof upblast configuration is ideal for exhausting contaminants away from a building to prevent roof damage and re-entrainment of exhaust air. Both QEI-I/II roof upblast models have the high temperature UL rating and can be used for emergency smoke exhaust applications.
