  • 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. A record of the vibration test result is available upon request. By performing the vibration test, we are able to provide more than wheel 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 uncover these problems before the fan leaves the factory. Electrostatic Powder Coatings Powder coatings offer a uniform, durable and high-quality finish. Standard 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 is resistance to many common chemicals. Consult Greenheck’s Product Application Guide, Performance Coatings for Ventilation Products, for a complete listing of coatings and a relative resistance chart. For corrosive environments (i.e. coastal), see page 9 for information on our zinc-rich basecoat technology.
  • 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. For additional information on sound, refer to page 6. Greenheck’s Sound Lab Field Rotatable Housing / Compact Size The QEI-L and QEI are 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 how the fan is installed or the position the motor is oriented. 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. Greenheck’s mixed flow fans were designed for compact size. Keeping size to a minimum is important when fitting into tight spaces like mechanical rooms or air handlers. Slip-Fit Duct Connections The inlet and outlet ends of the QEI-I/II and QEID are designed to accept “slip-fit” connections. Often companion flanges are bolted to a fan’s inlet/outlet flange to provide a slip-fit connection for a flexible sleeve, as with the QEI-L. 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.
  • Page 6 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 and centrifugal properties: highly efficient air movement, increased Mixed Flow pressure capabilities, extremely low sound levels, and a steep fan performance curve. To further enhance the fan’s performance, Axial 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. Airflow Profiles Axial Fans: Straight through nearly linear airflow. Centrifugal Fans: Two 90° deflections, before airflow exits the fan. Mixed Flow Fans: Slight airflow deflection from Axial Centrifugal Mixed Flow straight through. 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 (L A) and the static efficiency of the belt-driven mixed flow fan wheel versus tubular centrifugal and vane axial inline fans. Over a wide range of operating points, the mixed flow fan provides the quietest and most efficient selection.
  • 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. When selecting a mixed flow fan, it cannot be assumed that moving into a Class II fan will produce the same results as a Class I mixed flow fans. Model QEI-L utilizes a Class I wheel. Class II Class I Direct Drive: Percent Wheel Width Direct drive mixed flow fans are optimized for performance requirements by the use of partial width wheels. This is necessary because the fan RPM is commonly fixed and identical to the motor RPM. 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 5% increments from 50 - 100% wheel width. QEID fans can be 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 when building requirements are reduced. In this case, the fan and wheel width are selected using the Inter final design CFM and static pressure. Wheel 50% Wheel Width Width 100% Wheel Width Intermediate 100% Wheel...
  • 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. An electronics package with pressure transmitter and digital read out is available with the Sure-Aire™ system. The electronic kits are available for 50 or 60 Hz power supplies and provide a 4-20 mA output that can be tied into the building’s automation system. Sound Sensitive Areas Sound Vault Housing - Radiated Sound Enclosure The sound vault housing is an excellent product for fans that will be positioned adjacent to an occupied work space or in sound critical applications. It locks in radiated sound from the fan casing, motor and drives, and minimizes vibration transmission. Standard construction includes an acoustically lined housing, integral spring isolators, and internal flexible connections at the fan’s inlet and outlet to effectively isolate the fan from the system. Vertical or horizontal mounting configurations are available. Why use a Sound Vault? • Sound power attenuation levels determined by sound intensity tests on actual units • Ships fully assembled with fan • Internal isolation to limit breakout noise • Access panels for inspection of fan and motor • Bearing lubrication lines extended to outside of...
  • Page 9 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. Now, this advanced technology is available on Greenheck welded steel products. Greenheck’s coating process starts with a minimum of five wash stages to treat all components prior to painting. Cleaner parts result in better coating adhesion and durability. We then use an advanced two-coat powder application method that includes a basecoat of zinc-rich powder and a topcoat of Greenheck’s Permatector™ or Hi-Pro Polyester. The combination of these two topcoats over the zinc-rich basecoat results in the two-coatings, Perma-Z and Hi-Pro-Z. These oven-cured coatings provide superior corrosion resistance along with a tough, uniform finish to combat the most extreme conditions. Zinc Advantage When compared to a traditional single coat One Coat Process application, the benefits of the two-coat system include: Topcoat Standard 2-3 mils Surface Preparation • An automatic powder coat application that produces uniform coverage and Base Steel unmatched paint quality. • A double coat thickness that provides superior durability and protection from Two-coat Process Zinc-rich Primer air and water.
