Product overview
Dwt-i axial flow roof fan: suitable for low pressure, large flow applications. At the same time, according to the needs of users, it can also be designed as bidirectional rotation reversible type, which has the characteristics of equivalent positive and negative working conditions.
   high efficiency and low noise: the fan adopts advanced CAD software and is designed and developed by multi-objective optimization. Dwt-i series of 1200, 1400, 1500, 1600, 2000 and 2400mm fans adopt the method of the same diameter, different speed, different angle and different blade profile to meet the needs of different operating conditions, to match the fan with the system, so as to realize energy saving and noise reduction.
  light weight, high strength, corrosion resistance: the fan impeller can be made of ABS (engineering plastics), FRP (glass fiber reinforced plastic) and aluminum alloy plates according to the corrosivity of working medium. For centrifugal fans with high pressure requirements and high fan speed, the impeller surface is treated with special galvanizing and plastic spraying corrosion, which not only reduces the overall quality, but also has good performance Good corrosion resistance.
   balanced operation and long service life: the fan has small rotational inertia, high dynamic balance accuracy, stable operation, and the requirements of various performance indicators in the factory internal control standards are higher than the fan industry standards, which can ensure the long-term stable operation of the fan.
   wide range of application: the fan can be manufactured into explosion-proof type and anti-corrosion type according to the use requirements, which is suitable for anti-aging pumping, discharging inflammable, explosive and corrosive gases.
    beautiful appearance: the wind cap parts of the fan are made of glass fiber reinforced plastic, and the appearance adopts the imported gel coat resin film. The curved surface is too soft, beautiful and generous, and has strong practicability. It can also be made into steel hood according to the user's requirements and treated by galvanized plastic spraying (PVC).
It is not allowed to use the medium containing more than 100 mg of dust. In case of high medium temperature, the high temperature smoke exhaust fan of Shangyu ventilator can be made into roof fan for users.
   this product has been tested and qualified by the national quality supervision and inspection center of compressor refrigeration equipment. The test items include air volume, wind pressure, flame retardant, electrical conductivity, explosion-proof, wind resistance, etc., and is supervised by the General Administration of quality supervision, inspection and Quarantine of the people's Republic of China. And issued the national industrial product production license.
