Classification DWT roof fan roof fan roof fan category, a type called DWT roof fan, the entire roof fan in the family is still very status. And there are some unique performance advantages worth for us when it comes to the road. Some of the advantages with respect to DWT roof fan. DWT series roof fan with molded axial or centrifugal impeller, fan motor Direct drive, corrosion hood, metal or fiberglass duct base, steel hood, corrosion resistant, high strength and light weight, smooth operation, easy maintenance, low noise, excellent performance characteristics, widely used in power generation, chemical, rubber, pharmaceutical, food processing, metallurgy and other industries and senior civil ventilation. DWT-I type with broad leaves, big chord, axial flow impeller space warp tilt for low pressure, high flow ventilation occasions. DWT-II-type centrifugal impeller optimized for higher pressure situations exhaust ventilation. As long as we can be a good use of roof fan, roof fan then you can give us a very intuitive assistance benefits. I plant specializing in the production of steel, aluminum, stainless steel roof fan and hood, the model is complete. Centrifugal roof exhaust fan factory production advantages centrifugal roof exhaust fan will be flexible and stable rotation can play a windbreak, professionally produced steel hood, rain, snow effect. Axis with 45 # carbon steel made, with good resistance to deformation and corrosion resistance. Bearings imported fully enclosed self-lubricating bearings, sales of steel hood, lubrication-free, long life. Stents made with reinforced metal stents, it has a light weight, high strength, no rust anti-corrosion properties. Variable angle tube neck can (0-22.50) change depending on the angle of the neck of the roof slope, the horizontal stabilizer to keep the turbine head can rotate, greatly improving the ventilation of life. Centrifugal roof exhaust fan advantages: 1. unique variable angle tube neck design to be installed on the roof is very simple 0-22.50; 2. Efficient ventilation capacity; 3. wavy blade design lines, no leaking possible; 4. Special axis design of the bearing from the longitudinal tension, prevent blade deformation; 5. made of stainless steel, with good corrosion resistance, low starting torque, roof fan steel hood, the breeze can rotate row wind; 6. Closed imported self-lubricating bearings, durable, maintenance-free, no noise, no lubrication; 7. zero-cost operating costs; significant energy savings, installation cost economical, efficient ventilation effect; steel hood supply steel hood, Sheng clean air-conditioning (certified merchants) from the Texas Air Conditioning Equipment Co., Ltd.
