DWT-IV motorless turbine roof fan
DWT-IV motorless turbine roof fan product specifications and features: suitable for steel structure roofs, it is the preferred product for environment
Product details
product overview
DWT-IV type motorless turbine roof fan: suitable for exhaust and ventilation of roofs in commercial buildings and industrial enterprises (light steel structures).
High efficiency and low noise: This fan adopts advanced CAD software and has been designed and developed through multi-objective optimization.
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.
This product has been tested and qualified by the National Compressor Refrigeration Equipment Quality Supervision and Inspection Center. The testing items include air volume, air pressure, flame retardancy, conductivity, explosion-proof, wind resistance, etc. It is supervised by the General Administration of Quality Supervision, Inspection and Quarantine of China and issued a national industrial product production license.
Overview of DWT-IV type motorless turbine exhaust fan
DWT-IV type motorless turbine exhaust fan uses natural wind to drive the blades, generating centrifugal force to make the air flow. Due to the relatively thin blades, even weak winds can make it rotate. When the turbine rotates, a new force is generated to suck up and remove the hot air, smoke, and humid gases that are lowered from the turbine. When air is drawn away from the turbine, a low-pressure zone, known as the chimney effect, is conveniently formed directly below the turbine. Due to the continuous rotation of the turbine, fresh outdoor air also continuously flows in, thus achieving the effect of natural ventilation and cooling.
DWT-IV type motorless turbine exhaust fan does not require electricity, operates continuously, is efficient and energy-saving, and has no noise or sparks. The exhaust fan adopts arc-shaped blades, and the gaps between each blade are filled by the blades when they rotate. A large amount of rainwater is thrown out along the pitch line of the circle, while a small amount of rainwater flows down the roof along the blades and does not flow into the turbine. At the same time, the rotating turbine allows air to flow out through the gaps between the blades, blocking rainwater from entering, and has wind and rain resistance characteristics. The exhaust fan bearings adopt fully enclosed ball bearings, lightweight stainless steel blades or aluminum alloy blades. The whole machine is lightweight and has a long service life, generally with a service life of more than 15 years.
