Product Description

Product Description

  The DWT-I type axial flow roof fan has blades similar to those of the ZD type axial flow fan. It adopts wide blades, large chord nodes, spatial deformation and inclined blade shape.

At low speeds, the required air volume and air pressure can be achieved, thereby reducing fan noise

According to the diameter of the impeller, the fan is classified into seventeen specifications ranging from 300 to 2400mm. The air volume of this series ranges from 1,500 to 220,000 m ³ /h, and the air volume is complete

The pressure is 60-320Pa. Blades with a specification of 12 or more can be made into adjustable blade angles to meet different requirements

Working conditions. Achieve energy conservation and noise reduction

3. Depending on the environment, the fan can be made explosion-proof, suitable for non-corrosive places containing flammable substances.

Explosive gas and anti-corrosion types can be used in environments containing corrosive gases

4.In order to meet different working points, it can be equipped with a dual-speed motor to achieve dual-speed regulation, or it can be equipped

Stepless speed regulation is achieved by adopting variable frequency motors and variable frequency controllers. It is suggested to lock and adjust.

The frequency is between 25Hz and 50Hz.

 

 

 

 

Characteristics



1. Wide application range: The DWT-I type axial flow roof fan is suitable for low-pressure and high-flow usage scenarios. The DWT-II type centrifugal roof fan is suitable for small air volume and high-pressure occasions.



2. High efficiency, low noise, light weight, corrosion resistance, smooth operation and long service life.



3. The medium temperature should be less than 60° C. The gas must not contain excessive viscous substances, and the dust content should be less than 100mg/

m34

There are many types, which can meet the needs of different occasions. Other models of fans can be provided according to the needs of users.

5. Obtained the National Utility Model Patent and the National Excellent Patent Award
