Centrifugal fans are mechanical devices that increase gas pressure and discharge gases by relying on input mechanical energy, making them a type of driven fluid machinery. They are widely used for ventilation, dust extraction, and cooling in factories, mines, tunnels, cooling towers, vehicles, ships, and buildings; for ventilation and exhaust in boilers and industrial furnaces; for cooling and ventilation in air conditioning equipment and household appliances; for drying and selection of grains; and for inflation and propulsion of wind tunnels and air cushion vessels.

Zixu Air Conditioning Equipment Co., Ltd. specializes in the production of centrifugal fans, oblique flow fans, high-temperature centrifugal fans, fire dampers, and more. For more details, please consult us, and a dedicated staff member will be there to assist you.

Centrifugal fans are essentially variable flow constant pressure devices. When the speed is constant, the pressure-flow theoretical curve of a centrifugal fan should be a straight line. Due to internal losses, the actual characteristic curve is curved. The pressure generated in a centrifugal fan is significantly affected by changes in inlet temperature or density. At a given airflow rate, the pressure is lower when the inlet temperature is highest (air density is lowest). For a given pressure and flow characteristic curve, there is a corresponding power and flow characteristic curve for exhaust centrifugal fans. When the blower operates at a constant speed, the required power for a given flow rate increases as the inlet temperature decreases.

The working principle of centrifugal fans is basically the same as that of turbine compressors. Both operate due to low gas flow velocity and minimal pressure changes, generally without the need to consider variations in gas specific volume, i.e., treating the gas as an incompressible fluid.

Axial fans can be manufactured in two types: right-hand and left-hand. Looking straight at the motor side: the impeller rotates clockwise, referred to as a right-hand fan; the impeller rotates counterclockwise, known as a left-hand fan.

Centrifugal fans are composed of the housing, main shaft, impeller, bearing transmission mechanism, and motor, etc.

Case: Made of sturdy steel plate, offering both whole and semi-open designs, with the semi-open design facilitating maintenance.

Impeller: Composed of blades, a curved front disk, and a flat rear disk.

Rotor: Should be statically and dynamically balanced to ensure smooth rotation and good performance.

Transmission part: consists of the main shaft, bearing housing, rolling bearings, and belt pulley (or coupling).
