IDB Series Forward Curved Inline Duct Blowers

  • Wheel Diameters: 7” through 15”
  • CFM: Approximately 500 to 5700 CFM in a single blower.
  • Constructed from galvanized steel for durability.
  • 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.
  • Delhi blowers will not “surge”, “hunt” or “stall”.
  • The variable pitch motor pulley permits field adjustment (typically + or - 15%) to match air delivery needs.
  • Quiet forward curved blowers operate at ½ the rpm of other inline solutions.
  • Note: For insulated or heavy duty applications, please reference our 200 and 9200 series.
