The negative pressure fan, which is a kind of negative pressure fan, is the same as the ordinary negative pressure fan in the main function, and it plays the role of ventilation and cooling. There are certain differences in terms of materials and types. So below, let's take a detailed look at it so that we can make a good distinction.

FRP negative pressure fan, a kind of negative pressure fan, is made of glass fiber reinforced plastic with corrosion resistance in raw materials. Therefore, it is called a FRP negative pressure fan. From the point of view of properties, it belongs to the axial flow fan, and it is in the large category of ventilation equipment.

1. Working principle of FRP negative pressure fan

The working principle of the FRP negative pressure fan is specifically: the use of negative pressure to replace the air, that is, the ventilation operation, so that the inside and outside air flows, thereby achieving the purpose of ventilation and cooling. Also, it is also known that this type of fan has no refrigeration.

2. The main advantages of FRP negative pressure fan

For the FRP negative pressure fan, its main advantage is that it has good corrosion resistance and can achieve high air volume. In addition, the negative pressure fan can achieve three lows during operation, namely low speed, low noise and low energy consumption.

3. Application and classification of FRP negative pressure fan

FRP negative pressure fan, its application range is mainly in the ventilation of factory buildings, as well as the ventilation of some workshops with high temperature or odor. In addition, for corrosive environments, it is also possible to use a FRP negative pressure fan for ventilation.

The types of types of FRP negative pressure fans are different according to different classification criteria. If divided according to its appearance, the FRP negative pressure fan can be divided into two types: a trumpet-shaped FRP negative pressure fan and a square FRP negative pressure fan. According to the transmission method, there are two types of belt type and straight type. Therefore, we can also subdivide the FRP negative pressure fan.
