Overview

Model 9200 is a belt drive duct fan designed for interior/exterior supply, exhaust, make up air, or ducted return applications. Units feature forward-curved wheel, and powder coated housing. With accessory options such as filters, intake hoods and hot or chilled water coils for many different applications. Twin options available.

Applications:

  • An Inline make-up air solution for cases where a rooftop curb mounted solution is not available.
  • As an air moving module for systems built up with other components such as heating/cooling coils.
  • Noise sensitive areas - the low rpm forward curved wheel typically radiates less vibration than higher rpm backward inclined wheel solutions.
  • When the application requires an air mover in a duct system located in a ceiling space.
  • Redistribution or recirculation of air in a work space.
  • Interlocked with entry doors to prevent entry of cold outdoor air into retail sales space and thus greets customers with warmth.
  • Bathroom/ rest room exhaust - one duct blower serving multiple intakes.
  • Industries Served: Commercial HVAC, Ventilation, Heating, Cooling, Construction.

 

Features:

  • Wheel Diameters: 7” through 20”.
  • CFM: Approximately 500 to 12,500 CFM in a single blower (Twins available).
  • Static Pressure: Usage to about 3” static pressure is common, although allowable range is higher.
  • Constructed from cold rolled steel, with grey baked on powder coat. The outdoor unit uses protective galvaneal steel under the powder coat.
  • Forward Curved blowers operate at low RPM for low noise levels.
  • Heavy duty ball bearings suitable for -65º F to +250º F.
  • Keywayed shafts both ends for clockwise or counter clockwise rotation.
  • Saddle type motor mounting platform provides extended belt tension adjustment range on all models.
  • As part of an HVAC system Delhi Duct Blowers will not “surge”, “hunt”, or “stall”.
  • The variable pitch motor pulley permits field adjustment (typically + or - 15%) to match air delivery needs.
  • For the quietest operational needs we offer optional internal spring isolation of the blower/motor from the housing thus greatly reducing radiated cabinet noise.
  • Twin units (two duct blowers on a common shaft) offer a wide but not tall solution for situations where vertical space is limited.
  • Quiet forward curved blowers operate at ½ the rpm of other inline solutions.
  • 9200 series may be mounted vertically or horizontally. VIB option is horizontal mount only. Cannot ­­­­be vertically mounted.
