Induced draft fan (induced draught fan, ID fan) is the centrifugal fan, which creates suction on the outflow end of the process, drawing air to the inflow. In the mining, power plant, incineration, medical, automobile, machine tool and cement industries, ID fan is widely used.

Large energy savings can be realized by changing the flow control on air handling machines.

AC variable frequency drive (VFD) controls the frequency of the power of the motor. Then the motor speed can be adjusted to match the desired fan speed and flow. The energy used of induced draught (ID) fan is much less than using an output damper to control flow.

Retrofit of induced draft (ID) fan with VSD drive to reduce the electricity consumption, thus saving money!
