A Forced Draft Fan is a Fan/blower that creates a positive pressure, forcing air into a combustion chamber.

If u use a fan to force the air to a system to create positive pressure inside, i.e., if you mount it such a way that air blowing is from atomsphere to the system, then as per your application of the fan may be called as a Forced Draft Fan.

Remember if you put the fan in opposite direction, then air/gas from inside the system will exit the system, and will create a negative pressure inside, and hence as per your application it may be called as an Induced Draft Fan.

Dear Kanchan,

A fan can be used as Induced draft as well as Forced draft.

It means there is no difference in designing also like in their blades etc.

Please Reply

With warm Regards,
