  • Page 2: Features And Benefits

    1, 2 and 3. Arrangement 9 permits factory mounting of the motor on top, bottom, or either side of the fan — see below. AMCA Licensed Ratings The Trane Company certifies that the Model Q fans shown herein are licensed to bear the AMCA Seal.
  • Page 3 Double acoustic enhancement — insulation and perforated sheet metal to attenuate radiated sound • Fan insulation — self-adhesive foam, applied on the outside of the fan shell to protect against moisture • Variable frequency inverter balancing and reinforcement (frequency inverter by others).
  • Page 4 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.
  • Page 5 Variable Air Volume Compatible The Super Q fan is modulated for VAV with variable frequency drives (by others), not with inlet vanes. Variable speed inverter fan modulation offers exceptional energy saving and exceptionally quiet part load operation.
  • Page 6 It provides proven acoustical performance with less design risk. In project after project, the Trane Model Q fan has been the key to creating NC 15 to NC 35 quiet comfort jobs. Beyond quiet, the Super Q II Plus system is small and compact.
  • Page 7 [7] Hub Streamlining Insulation [12] End Cone [8] Exact Blade to Vane Spacing [11] Precise Divergent Angle Diffuser Discharge Cone Precision cast fan wheel and diffuser for highly efficient aerodynamic performance.

  • Page 8 Benefits The aerodynamically shaped inlet bell [2] and inlet cone [3] provide uniform axial flow parallel to the fan shaft. Air is delivered equally to the leading edge of the fan blades — no crowding toward the fan tips.
  • Page 9 Because of its size and weight, it is floor mounted and connected to a return air plenum. In contrast, a 44-inch Model Q fan is used in Figure F-2 instead of a centrifugal fan. Its smaller size and lighter weight permits ceiling suspension and approximately 75 sq ft of floor space is freed up for other use.
  • Page 10 Blow-Thru Supply Application Figure F-7 shows a typical medium pressure, built-up, blow-thru system. The fan, enclosed in a plenum, is a 33- inch, double width, airfoil centrifugal that delivers 30,000 cfm of air. The bulkiness of the plenum is dictated by the necessary clearances around the fan.
  • Page 11 Install Isolation Average Total Installed Cost Comparison is based on equal size fans of similar capacities. The airfoil centrifugal fan is used as base (100%) for comparative purposes. Figures are based on estimates by experienced installing contractors. Arrangement 9 Trane Model Q fan...

  • Page 14 Performance Data Determination 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 Testing Fans for Rating.
  • Page 15 Isolates fan *Note: Bellmouth effect included in unducted installation Kt correction. Fan sizes 49 through 60 fan curves are cataloged with inlet bells. For unducted inlets without bells on size 49 through 60 fans add .1 to the inlet Kt given above.
  • Page 16 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. This option “beefs up” the...
  • Page 17 40 percent wocfm, whichever is greater. Forty percent wocfm is the minimum point a Q fan with inlet vanes can modulate, due to inherent instability that results when the vanes close to a certain angle.
  • Page 18 Minimizing belt tension forces increases bearing life and reduces fan noise. The Q fan and Super Q II fan drive selection is totally computerized by the factory to achieve quiet, long life operation. If Trane provides Q fan...
  • Page 19 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. Designers can compare the Q fan efficiency with other...
  • Page 20 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.

  • Page 21: Selection Procedure

    63 Hz 125 HZ 250 Hz 500 Hz *Approximate attenuations. Use the Trane Fan Selection Program for attenuation predictions that include silencer regenerated self-noise. NOTE: Super Q II not available with Class III fans. If inlet vane modulation was selected, increase the rpm by 1 percent and increase the bhp by 3 percent.
