Features and Benefits Q Fan • Flexible Installation Benefits ™ The Model Q fan is a quiet, airfoil, inline 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. Small and compact, the Q fan has proven to be the ideal air moving device for standalone applications and also for custom air handling units. It can be used for supply, return and exhaust systems.
Contents Q Fan Accessories Features and Benefits • 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. • Inlet vanes — mechanically modulate fan capacity • Inlet bellmouth — used with unducted or plenum applications. Improves air flow and reduces noise.
Features and Benefits This chart shows a typical NC level comparison between common vaneaxials, tubular centrifugals, airfoil centrifugals and the Trane Model Q™ compact fan. The shaded area represents range of vaneaxials tested. Trane Model Q fans require up to 85 percent less cubic space than airfoil centrifugal fans and 40 percent less than common vaneaxials of equivalent installed sound level.
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 HVAC fans in the world. This tradition of excellence continues with the introduction of a new Q fan acoustical enclosure and duct silencer so effective and so compact that we named it the Super Q II.
Features and Benefits Trane 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. Briefly, the Plus option develops maximum static regain while simultaneously limiting objectionable mid and high frequency noise. The Plus option should be used whenever quiet comfort is desired and the duct system is acoustically unable to provide it.
Features and Benefits Low Sound Level, High Efficiency Provided by Unique Aerodynamic Features [9] Airfoil Vanes (stationary) [4] Airfoil Blade Wheel.
Features and Benefits The low sound and high performance of the Trane Model Q™ fan are achieved by reducing noise-creating, energyconsuming 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. The resulting smooth air path has made the Model Q the first vaneaxial fan to provide quiet, efficient operation, suitable for air conditioning duty.
Features and Benefits Saving Valuable Equipment Room Space The Trane 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. Return or Exhaust Applications Figure F-1 shows a size 44, single width, low pressure airfoil centrifugal fan delivering 20,000 cfm of air. Because of its size and weight, it is floor mounted and connected to a return air plenum.
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 45,000 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.
Features and Benefits Reduce Installed Cost By Up To 20 Percent The Trane 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. First Cost Comparisons True first cost is the total cost of an operable installation.

Application Considerations This section assists the system designer in application and control of Trane Q and Super Q II fans. Satisfactory distribution of conditioned air requires a properly chosen fan and a well designed duct system.

Application Considerations Performance Data Determination The fan performance section of this catalog contains a fan performance table and fan curve for each fan size. Figure A-2 — Point of Operation — Interaction of the System Curve and the Fan Performance Curve The performance data contained in this catalog was calculated from tests conducted in accordance with AMCA Standard 210 Laboratory Methods of Testing Fans for Rating.
Application Considerations 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 nonstandard 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. 4 The rpm is correct as selected.
Application Considerations Q and Super Q II Fan Modulation — AC Inverter Capacity Control Q fans and Super Q II fans can be modulated with AC frequency drives. The Trane Company recommends Magnetek low noise inverter drives and Century high efficiency motors for optimum modulation performance. Operating the Q or Super Q II fan on AC frequency drives requires the Q fan to be strengthened and balanced in the factory.
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. The minimum inlet vane cfm can easily be determined after the system modulation has been established.

Application Considerations Recommended Super Q II (NC40) Plenum Configuration Recommended Super Q II Multiple Fan (NC40) Low Height Plenum Configuration Recommended Super Q II Quiet (NC35) Floor-Mounted (Stacked) Configuration 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.
Application Considerations Q Fan Sound Data Trane 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 centrifugal fans with the same capacity. Sound levels in the higher octave bands compare favorably. Therefore, the Q fan will provide quieter sound levels in a typical installation.
Selection Procedure 1 Select the type of fan desired. The Super Q II should be used where fan radiation noise needs to be attenuated. 2 Position the Q fan to deliver air to the system and minimize adverse Kt effects. Straight-thru flow arrangements are best. 3 Select the desired Q fan or Super Q II fan options. 4 Compute the fan external static pressure and cfm requirements. 5 Determine which Kt effects apply to the Q fan installation.

Mechanical Specifications Q FAN ASSEMBLY Housing Housings are 14-gauge steel hydraulically expanded to form integral inlet bell and diffuser sections. Hydraulically expanded stiffening ring welded in area of wheel raceway. On VAV variable speed fan units, fan inlet supports are structurally reinforced to handle extra stresses of variable speed fan modulation and fan is balanced at ten different fan speeds over the desired operating range.
Mechanical Specifications ACCESSORIES Inlet Screen (Q, SQ2) Heavy-gauge steel wire mesh. Inlet Bellmouth (Q, SQ2) On unducted inlets, the radius bellmouth uniformly accelerates air into the fan, reducing noise and energy requirements. Plus Duct Silencer (Q, SQ2) Significantly attenuates fan airborne sound levels. Center body of round silencer is dimensional matched to Q-fan hub. Center body is field adjustable in the direction of airflow.
