Super Q II Fans Sizes 16 through 44 Model Q ™ Fans Sizes 16 through 60 F AN-DS-2 A ugust 20 0 0 F AN-DS-2 Super Q II Fans Sizes 16 through 44 Model Q Fans Sizes 16 through 60.
2 Features and Benefits ©American Standard Inc. 2000 Q Fan The Model Q ™ fan is a quiet, airfoil, in- line fan specifically designed for air conditioning applications. This highly refined axial flow fan is available in 13 sizes from 1,000 through 80,000 cfm.
3 Contents Q Fan Accessories • Inlet flange — for simplified, rigid connection of ductwork to inlet end of fan • Inlet screen — safety accessory mounted to fan inlet. Heavy , plated steel wire Note: inlet screen and inlet flange are mutually exclusive.
4 This chart shows a typical NC level comparison between common vaneaxials, tubular centrifugals, airfoil centrifug als and the T rane Model Q ™ compact fan.
5 Features and Benefits Super Q II Plus More than twenty years after the introduction of the Model Q ™ , it still retains its reputation as one of the quietest HV AC fans in the world.
6 Features and Benefits T r ane Plus Duct Silencer The Plus option is a high performance duct silencer . Designed specifically for the Super Q II and Model Q ™ , it has several unique features that reduce airborne noise and turbulence to exceptionally low levels.
7 Features and Benefits Low Sound Level, High Efficiency Provided by Unique Aerodynamic Features [7] Hub Streamlining Insulation [9] Airfoil V anes (stationary) [10] Stabilizing Pitch [4] Airfoil Blade Wheel.
8 Features and Benefits The low sound and high performance of the T rane Model Q ™ fan are ac hieved by reducing noise-creating, energy- consuming turbulence within the fan. Airflow research and development techniques employed were similar to those used in perfecting today’ s high performance axial flow jet engine compressors.
9 Features and Benefits The T rane Model Q ™ and Super Q II fans can help you maximize your building’ s usable floor space by using them in place of centrifugal fans. The smaller the equipment room, the more space left for tenants, merchandise, etc.
10 Features and Benefits Draw-Thru Supply Application (Large Capacity) A 60-inch, single-width, medium pressure airfoil centrifugal fan is used in the system illustrated in Figure F-5 to supply 45,00 0 cfm of air . This capacity can be easily achieved by installing a pair of 40-inch Model Q™ fans in parallel as shown in Figure F-6.
11 Features and Benefits The T rane Model Q ™ fan, with all its precision and quality , is still a cost effective fan. When all necessary system components are considered, it provides substantial installation cost savings. In addition, its small size and variable mounting positions allow more freedom to the designer and installer .

13 Application Considerations This section assists the system designer in application and control of T rane Q and Super Q II fans. Satisfactory distribution of conditioned air requires a properly chosen fan and a well designed duct system. Abbreviations sp .
14 Application Considerations P erfor mance Data Det ermination The fan performance section of this catalog contains a fan performance table and fan curve for each fan size. The performance data contained in this catalog was calculated from tests conducted in accordance with AMCA Standard 210 Laboratory Methods of T esting Fans for R ating.
15 The following is the procedure to use when selecting a fan for elevations and temperatures other than standard: 1 Determine the air density from Figure A-3. 2 Divide static pressure at the non- standard condition by the air density ratio. 3 Use the actual cfm and corrected static pressure to determine rpm and bhp from the fan performance tables.
16 Application Considerations Q and Super Q II Fan Modulation — AC In ver ter Capacity Control Q fans and Super Q II fans can be modulated with AC frequency drives. The T rane Compan y recommends Magnetek low noise inverter drives and Century high efficiency motors for optimum modulation performance.
17 Application Considerations The control static pressure can then be expressed as a percent of peak static pressure and plotted. The system modulation curve is described by the curve on the modulation overlay that passes through the design point when the axis is placed on the control static pressure point.
18 Application Considerations Parallel Fan Operation The Q fan performance curve has a characteristic shape where two dif ferent cfm’ s are possible at the same static pressure.
19 Recommended Super Q II Quiet (NC35) Floor -Mounted (Stack ed) Configuration Application Considerations Operating Cost/Efficiency The quiet Q fan is a very efficient fan. The Q fan mixed-flow type airfoil thrust blades offer outstanding efficiency and operating cost savings over such fan types as plug fans.
20 Application Considerations Q Fan Sound Data T rane Q fans are designed to be used in any installation where a standard airfoil centrifugal fan can be used. The sound level of the Q fan in the difficult to attenuate lower frequencies is lower than that produced by standard airfoil centrifug al fans with the same capacity .
