The centrifugal fan is a fan with a variation between the air entrance and exit axis (due to the snail shape of the body). The centrifugal shape of the body allows some of the air velocity to be converted into pressure on the blade. Due to this feature, it can provide very high pressures coperation to axial fans.

General Usage Areas of centrifugal fans are available in many areas such as Cement Factories, Iron and Steel Factories, Forest Products Processing Factories, Mining, Petrochemical, Glass and Paper Factories, Suction in Dust Collecting Systems, Production Factories and Ventilation Centers.

Advantages of Centrifugal Fans:

-High efficient (based on the energy consumed)

-Low energy costs.

-Providing high flow values.

-Working in high pressures.

-Working in extreme hot environments

-We have advantages such as transportation of abrasive materials.

– Allows without the need for equipment.

1) Duct Fan: The Duct fan works by reducing the pressure of the environment. In air conditioning, it is necessary in systems that work with indoor and outdoor air mixture. Duct fans ensure that the air in the air conditioned environment is returned in an appropriate amount. In systems with surplus pressure, Duct fans operate at a lower flow rate than discharge fans.

2) Exhaust Fan: Exhaust fan is used in systems that work with internal-external air mixture but without duct fan and provides exhaust air as much as intake air. In these systems, the discharge fan must be selected to meet the static pressure generated in the system in the absence of outside air. In the case of outside air, the exhaust fan ejects a slightly lower amount of return air than the intake air, thereby creating a surplus pressure in the space.

3) Discharge Fan: The fan connected to an air duct creates surplus pressure within the duct and provides air movement. This type of fans are called discharge fans.
