What are the advantages of centrifugal fans?

Advantage One: This ventilator excels in both ventilation and air exchange, and its exhaust performance is equally impressive. Therefore, it is highly suitable for pipeline exhaust or air supply applications.

Benefit Two: Highly adaptable, suitable for various environments. Certain models, such as the 4-72 centrifugal fan, are designed for use in environments with flammable or explosive gases.

Benefit Three: This type of fan operates with minimal noise and maintains stability, even without vibration reduction equipment, the amplitude of the fan bearing remains extremely low.

Benefit Four: The centrifugal fan, with its durable housing and impeller made from steel plate, is designed for long-term use. Additionally, the entire unit has been coated, enhancing its performance. As a result, its lifespan can be significantly extended.

2. In the rated capacity of centrifugal fans, how should one understand the divisions such as 4#, 6#, and 8#?

In the rating of centrifugal fans, when divided by the numbers 4, 6, 8, etc., it specifically refers to:

4# Centrifugal Fan: The diameter of the intake is 400mm.

6# Centrifugal Fan: The intake diameter of this fan is 600mm.

8# Centrifugal Fan: The diameter of the fan's inlet is 800mm.

So, the 4#, 6#, and 8# in centrifugal fans refer to the diameter of the fan's intake. Additionally, for both roof-mounted and axial fans, the same applies. In essence, this notation is universal across these three types of fans.
