Quick Overview

IDL Series Low Profile Inline Duct Blowers


IDL MOTOR

Details

  • Use as part of an HVAC system.
  • Durable galvanized steel construction.
  • Delhi forward curved blowers will not 'surge', 'hunt' or 'stall'.
  • Ideal for indoor applications.
  • Optional variable pitch motor pulley permits field adjustment (typically + or - 15%) to match air delivery needs.
  • Quiet forward curved blowers typically operate at 1/2 the rpm of other inline solutions.
  • Low profile design for use in bulkheads or other areas with reduced clearance.
  • Easy to use drop down access panel provides quick access to blower and motor.

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 workspace.
  • 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. 
  • Ideal for use in bulkheads and other areas with low clearance.

Features:

  • Wheel Diameters: 7” through 15”.
  • CFM: Approximately 500 to 5700 CFM in a single blower.
  • 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 IDL models.
