what is the difference between id fans and fd
fans

Answer Posted / nikhil0381

#ID Fan - Induced Draft Fan

#FD Fan - Forced Draft Fan

Both ID fan and FD fan are basically centrifugal air blowers

Or inversely speaking,

A Centrifugal Air Blower is called ID Fan or FD Fan based on its use.

FD Fan pushes the air into the system. The system may be furnace/ boiler/ etc. In furnace & boilers FD Fan sucks the fresh air from atmosphere and supplies it to the burner for combustion. FD Fans are normally direct driven fans.

ID Fan pulls the air out of system. The hot flue gases such from the furnace/ boiler are sucked by ID Fan and thrown into atmosphere (via chimney). ID Fans for high temperature flue gases are belt driven fans.
