Radial fans are industrial workhorses because of their high static pressures (upto 1400 mm WC) and ability to handle heavily contaminated airstreams. Because of their simple design, radial fans are well suited for high temperatures and medium blade tip speeds. Forward-curved fans are used in clean environments and operate at lower temperatures.

ID fan creates negative pressure or suction to discharge the gases out after combustion from the furnace. Since ID fans can handle hot flue gases, they have more corrosion and erosion problems even when used with Electrostatic precipitators. The most common type of fans used as ID fans are the backward inclined blade centrifugal fans.

Induced Draft Industrial Fans | AirPro Fan & Blower

Aug 13, 2008 · Induced draft fan or ID Fan is required to evacuate the exhaust gases from Boiler to atmosphere through Duct collectors and chimney. Usually ID should take care of draft loss across the Boiler from furnace to Air heater and then draft loss across Duct Collectors like ESP, Wet Scrubber or mechanical type Cyclone dust collectors .etc.


Industrial induced draft fans operate by focusing the pressure and volume at the inlet of the fan to pull air through a system. Situated above the bundle, these fans create negative air pressure. They can work in concert with forced draft fans to maintain efficient and steady air pressure, and control the flow using VFDs, dampers, & other
