DWT-I axial flow roof fan: suitable for low-pressure and high flow applications. At the same time, according to user needs, it can also be designed as a bidirectional rotating reversible type, with the characteristic of equivalent forward and reverse working conditions.
High efficiency and low noise: This fan adopts advanced CAD software and has been designed and developed through multi-objective optimization. The DWT-I series machines with numbers 1200, 1400, 1500, 1600, 2000, and 2400mm adopt the same diameter but different speeds, angles, and blade shapes to meet the needs of different operating conditions, achieve fan system matching, and facilitate energy conservation and noise reduction.
Lightweight, high-strength, and corrosion-resistant: The fan impeller can be made of different materials according to the corrosiveness of the working medium, including ABS (engineering plastic), FRP (fiberglass reinforced plastic), and aluminum alloy sheet. For centrifugal fans with high pressure requirements and high fan speeds, the impeller surface is treated with special galvanizing and spray corrosion treatment, which not only reduces the overall weight of the machine, but also has good corrosion resistance.
Balanced operation and long lifespan: This fan has low rotational inertia, high dynamic balance accuracy, smooth operation, and all performance indicators meet higher requirements than the fan industry standards in the factory's internal control standards, ensuring long-term stable operation of the fan.
Wide range of applications: the fan can be manufactured into explosion-proof and anti-corrosion types according to the use requirements, and is suitable for anti-aging pumping, discharging flammable, explosive and corrosive gases.
Beautiful appearance: The hood components of this fan are made of fiberglass, and the exterior is made of imported rubber coating resin film. The surface is excessively soft, beautiful and generous, with strong practicality. The steel hood can also be made according to user requirements and treated with galvanized spray coating (PVC).
Usage conditions: The medium temperature should not exceed 60 ℃, excessive viscous substances are not allowed in the gas, and the water content and dust content should not exceed 100mg/m3. For situations where the medium temperature is high, the fire-fighting high-temperature smoke exhaust fan of Shangyu ventilation fan can be made into a roof fan for users to use.
