Design & Performance Hybrid Design A hybrid wheel is a cross 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. These serve to convert swirling airflow into a straight axial flow with a resulting static pressure rise and energy savings. Profiles Static Pressure Double Width Cabinet Hybrid Axial Double Width Cabinet Sound and Efficiency Sound power levels and fan efficiency are two very important factors when selecting a fan. There is a noticeable difference between impeller types. The table and chart below compare the sound power (LwA) and the static efficiency of the QEI wheel versus a double width cabinet and axial inline fans. The QEI provides the quietest and most efficient selection over a wide range of operating points. Performance, cmh @ Pa, cmh @ Pa, cmh @ 1 Pa QEI Size Axial QEI Sound Power LwA Double Width Cabinet (Model comparisons based on similar outer tube diameters.) Hybrid Axial Double Width Cabinet Fans: Two 9 deflections before airflow exits the fan. Axial Fans: Straight through, nearly linear airflow. Hybrid QEI Fan: deflected by two turns. QEI Static Efficiency Double Width Cabinet M 9 db 1 db 91 db % 1% % M db 11 db 1 db % % % M9 91 db 1 db 19 db 71% % 7% Axial Lower Sound Power, Better Sound Quality Sound power levels shown at each frequency: Sound Power, db 11 1 9 7 Typical Double Width Cabinet Typical Axial QEI 1 1 Frequency, Hz The sound quality of the QEI is as beneficial to low sound design as is the reduced overall sound power. The sound chart compares units of similar outer tube diameters at an operating point of, cmh with 7 Pa of static pressure (Ps). Double width cabinet (yellow) have dominant tones in the Hz through Hz octave bands, while axials (red) have more mid to high frequency sound. A bystander would hear a more bland sound that is quieter than a double width cabinet or axial.

Value-Added Features Vibration Testing Before shipment, every hybrid fan is vibration tested as a complete assembly using Greenheck s state-of-the-art digital spectrum analyzer/balancer instrument package. This system uses two tri-axial accelerometers to measure vibration from six inputs simultaneously. The maximum allowable vibration on a QEI at the fan bearings is.1 mm/sec. peak velocity, filter in, for the specified fan. QEID maximum vibration is. mm/sec. peak, filter-in, on the fan housing for the specified. A record of any vibration test result. or it s Vibration Signature is available upon request. By performing the vibration test, we are able to provide more than simply trim balancing; it is also a diagnostic tool for finding potential problems. A defective bearing or motor, bent shaft or misaligned sheaves may cause excessive vibration. A complete vibration test will find these problems before the fan leaves the factory. Electrostatic Powder Paint Powder coatings offer a uniform, durable and high quality finish. Powder coating is a one-coat process applied over a phosphatized surface that generally meets or exceeds the corrosion resistance of a comparable wet paint. Greenheck offers a number of in-house coatings applied via electrostatic powder. The standard coating, Permatector, is excellent for indoor or outdoor applications and also has resistance to many common chemicals. Consult Greenheck s Product Application Guide, Performance Coatings for Ventilation Products, for a complete list of coatings available and their chemical resistance. Available on-line at greenheck.com. Maintenance / Serviceable Construction Advantages The following value added features are incorporated into the design to allow for quick and easy field service. Belt Drive service advantages (QEI) Bearing lubrication is performed through extended grease fittings located on the outside of the fan housing. The entire shaft and bearing assembly can be removed as a single assembly from the inlet end of the fan housing. An adjustable motor base is provided for tightening the fan belts. Direct Drive service advantages (QEID) Grease lubrication on motor bearings is done through extended grease fittings for IEC motor frame sizes 1 and over. Smaller frame motors use sealed bearings and are permanently lubricated.

Inlet and Outlet Sound Power Levels All sizes and configurations 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. Field Rotatable Housing / Compact Size The QEI is designed to accommodate changing fan mounting positions and motor orientation in the field. Mounting fixtures are securely bolted to the fan casing and can be relocated to reposition to accomodate how the fan and motor must be orientated. Flexibility in a motor s location is important for easier access and can determine where the unit will fit. Last minute design changes or unexpected obstacles during installation are no longer a problem. The QEI and QEID were designed for compact size. Keeping size to a minimum is important when fitting into tight spaces like mechanical rooms or air handlers. Patented (QEI/QEID) USA Patent No. 799 China (P.R.) Patent No. CN191C Mexico Patent No. Slip-Fit Duct Connections The inlet and outlet ends of the QEI and QEID are designed to accept slipfit connections. Often companion flanges are bolted to the fan to provide a slip-fit connection for a flexible sleeve. This extra step is now eliminated by directly attaching the flexible sleeve to the duct and fan. This saves time and money in the installation process. It is recommended to use a flexible sleeve connection instead of a rigid duct connection. The advantages of a flexible transition are: Decreased sound transmission in the ductwork Duct Flexible connections allow for minor misalignment Accommodates the use of thrust restraints to resist thrust loads. AutoCAD Drawings Scaled AutoCAD drawings are available through Greenheck s website or from the Greenheck CAPS program which retrieves drawings and places them automatically into a job folder.

Optional Features & Model Number Code Sure-aire The Sure-Aire airflow monitoring station measures airflow within an accuracy of -%. Unlike traditional flow probes that block air passing through the inlet of the fan venturi, the Sure-Aire does not interfere with airflow and will not impact the fan s air or sound performance.

Wheel Characteristics Belt Drive: Fan Class Class I and II fans have different wheel designs with different performance characteristics. Class I hybrid 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 s. When selecting a hybrid fan, it cannot be assumed that moving into a Class II fan will produce the same results as a Class I. Class II Static Pressure Class I Direct Drive: Percent Wheel Width Direct drive hybrid fans are optimized for performance requirements by the use of partial wheel widths. This is necessary because the fan is fixed and identical to the motor. A reduction in the width of the wheel (or the air passage) results in reduced airflow capacity and a steeper fan curve. This is similar to the effect of a reduced pitch in a direct drive vane axial fan. QEID wheels are available in % increments from - 1% wheel width. QEID fans are commonly used in conjunction with variable frequency drives (VFD s) for variable air volume (VAV) systems. In these applications, the wheel width is optimized to ensure efficient operation and stable performance throughout the turndown range. VFD s are also used for final system balancing and to reduce the airflow during initial phases of building construction. In this case, the fan and wheel width are selected using the final design and static pressure. Static Pressure % Wheel Width Intermediate Wheel Widths 1% Wheel Width % Wheel Width 1% Wheel Width Sound Power versus Sound Pressure The sound values displayed on the performance pages are in terms of inlet sound power (LWi A) and outlet sound power (LWo A). These values are the acoustic power radiating from the inlet and outlet of the fan, respectively. Sound pressure, expressed as dba, is the acoustic pressure at a point in space which can be measured with a microphone or can be heard. To convert sound power (LWA) into sound pressure (dba), the following corrections are applied for a hemispherical free field. dba = L W A - correction Distance from Fan.9 m ( ft.) 1. m ( ft.). m (1 ft.)
