What fan is used for smoking in the kitchen?

Centrifugal fan is the choice of most catering kitchens, because the wind pressure provided by single-stage centrifugal fan is relatively large, while the flow provided by axial fan is large but the wind pressure is small, which is not suitable for the requirements of range hoods.

Axial flow fan and centrifugal fan are two different products in the category of fans, and their main function is also to ventilate the air in the environment.

The following are the differences between axial fans and centrifugal fans:

1. Different exhaust directions: the exhaust direction of the axial fan is straight along the axis, the air inlet and exhaust outlet of the fan are parallel to the axis, and the exhaust direction of the centrifugal fan is perpendicular to the air inlet direction, which can achieve 360-degree exhaust in the specified direction.

2. Installation difficulty is different: the installation of axial flow fan is relatively simple, generally it is directly installed on the wall or connected to the air duct. The installation of centrifugal fan is complicated.

3. The difference between air volume and wind pressure: the air volume and wind pressure of axial fan are relatively small, and there is basically no wind pressure, while the air volume and wind pressure of centrifugal fan are relatively large. If there are many elbows in the pipeline, the distance between air suction and air supply is long, and the pipeline resistance is large, centrifugal fans must be used.

4. Different appearance shapes: the axial flow fan is basically cylindrical in appearance, while the centrifugal fan is snail in appearance.

5. The motor connection mode of the fan is different: the motor connection of the axial fan is generally in the body of the fan, and the motor of the centrifugal fan is connected by a shaft, which is generally outside the exhaust pipe of the fan.
