Axial flow roof fan (DWT-I type)
Product Description: Axial flow roof fan (DWT-I type) is suitable for ventilation and air exchange in medium and low pressure, high flow places such a
Product details
1、 Overview of Axial Flow Roof Fan (DWT-I Type)
1. The axial flow roof fan (DWT-I type) has blades similar to the DZ type axial wheel fan, using wide blades with large chord space distortion and inclined blade shape, which can achieve the required air volume and pressure at low speeds, thereby reducing fan noise.
2. The fan is divided into seventeen machine numbers according to the impeller diameter of 300-2400mm, with a series air volume of 1500-22000m ³/h and a total pressure of 60-320Pa. The fan blades with machine numbers greater than or equal to 12 can be made with adjustable page angles to meet different working conditions and achieve energy saving and noise reduction.
3. Fans can be made into explosion-proof types according to different environmental requirements, suitable for non corrosive places containing flammable and explosive gases, while anti-corrosion types can be suitable for environments containing corrosive gases.
4. The performance adjustment requirements for different operating conditions can be met by using a dual speed motor to achieve two speed regulation, or by using a variable frequency motor and controller to achieve stepless speed regulation. It is recommended to lock the adjustment frequency between 25HZ and 50HZ
5. The fan can be equipped with manual or electric regulating valves, white louvers, etc. according to user needs.
