Industrial roof ventilation introduction

Low noise roof fan adopts mould pressing axial or centrifugal impeller, direct drive of motor, anticorrosion cap, metal or glass steel duct. It has the advantages of corrosion resistant, light weight and high strength, stable operation, simple maintenance, low noise, good performance. Widely used in power generation, chemical, rubber, pharmaceutical, food processing, metallurgy industries etc. and ventilation of high civil buildings. According to the environment and the use of different transmission medium, impeller can be made of aluminum alloy, steel plate, engineering plastics, glass fiber reinforced plastic and other materials, made to conventional type, anti-corrosion, explosion-proof, anti-corrosion explosion-proof type.


Characteristic

1. It has many specifications and a wide range of applications. According to the use of occasions and air volume, pressure and noise of the different requirements, the following three types of fans are selected.

1)Axial flow type roof fan: Applicable to low pressure, large flow applications. According to the user's needs, the bidirectional reversible air supply and exhaust fan can be designed, that is, the fan with the equivalent characteristics of positive and negative working conditions.

2)Centrifugal type unroofed fan: It is suitable for occasions with small air flow and high pressure requirement.

3)No motor turbine exhaust fan: It is a kind of energy saving ventilation device with outdoor air difference to drive the special arc blade rotating along the axis so as to discharge the indoor air.

2. High efficiency, low noise. The wind machine adopts the advanced CAD software, designs through the multi-objective optimization. By changing the speed, angle and blade type, the performance parameter range can be extended to meet the needs of different working conditions, so as to achieve the matching of fan and system to achieve energy saving and noise reduction;

3. Smooth operation, long service life. The moment of inertia of the roof fan is small, high precision of dynamic stability, smooth running.

4. Wide application: The fan can be made into explosion-proof, anti-corrosion type according to the requirement of use, suitable for flammable, explosive and corrosive gas occasions forced exhaust.
