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.
