Hvls Ceiling Fan

HVLS industrial Fan is a super larger energy-saving fan with a diameter up to 7.3 meters (24ft), the airfoil blade, which are developed with the advanced technologies and principle of aerodynamics. A power of 1.5kw or less, that more a High Volume (13,500m�³ /min) of air at a Low Speed and cools up to 1000 square meters, produce a large scale of natural wind, which leads to the double functions of ventilation and temperature cooling, as well as dehumidification. It is the ideal solution to ventilation and cool the air in large spaces.

Dawang fans Advantage: 1.Blade shape- Streamlined variable cross-section Blade gradually narrows from root to tip and thins to tail then widens like plane wing, more conform to the equal string length theory of aerodynamic Fan volume is more even, higher and there is no hole in the middle, low air resistance, save energy consumption. 2.Blade weight-light Each blade is 7.7KG,total weight for 5pcs is 38.5KG.Small blades ,light weight, reduce the motor load, increase the fan life.Low energy consumption. 3.blade petiole joint -- full mortise and tenon joint The "convex" shape petiole and "concave" shape buffer device are locked with bolts, each blade is riveted together with damping device by 16 rivets. Blade, damping device and petiole become a whole, torsional and shear force reduced. 4.blade angleâ??3 degree up Variable section design, tip 3 degrees higher than root, improving the air flow from cylindrical to conical, increase coverage, more than 1500 square meters. 5.petiole and wheel hub joint Lock petiole in the pistion on the hub through the concave and convex surface.Petiole and chassis hub form an integral whole to prevent blade from upwarp, falling and waggling It can load more than 8 tons tensile force

Dawang fans function 1. Ventilation Our Fans can promote the air circulation, perfect streamline make users enjoy the 2-4 m/s spatial formula air supply, form the nature breeze system, promoting dispersion of heavy dust, moisture, Co2 and poor air to improve the air quality, create a healthy, dry and safety work environment, enhance the work efficiency 2.Convenient Adopted the latest frequency conversion stepless speed control system, convenient to use. Humanized operation interface make users to enjoy the beauty of science and technology of life 3.Drying:Large air volume promote air flow effectively, make moisture well disperse and decrease the problems appear probability such as bedbug, mycete and so on 4.Elegant and durable:After complex surface treatment, the fan can avoid cleaning. The fan life can more than 10 years. 5.save energy and reduce consumption:The rated power of whole machine is 1.5kw, which can cover more than 1400m2 area, energy consumption is only 0.8 KWH. Compared with small powerful fans and high-power air conditioners, which reduces your costs greatly
