8ft to 24ft Industrial Ceiling Mounted Exhaust Fan for high ceiling factory

8ft to 24ft Industrial Ceiling Mounted Exhaust Fan for high ceiling factory   Our hvls ceiling fan is a new solution of Energy Saving to solve ventilation,
cooling and dehumidification in large indoor place.
  It is High Air Volume and Low Rotating Speed
  The traditional fan runs at high speed with high power consumption.it is damaged easily and the air covering space is also small .
But our HVLS super ceiling fan runs at low speed to slowly move a lot of air in large area through unique fan blades Our HVLS Ceiling fan only have 4 blades. From the center along the blades, blade's width and thickness gradually are narrowed and thin, in accordance with the modern aerodynamical  science, the whole blades drive more and even airflow downward, no empty zone in center area. The streamline design of the (windward side)  cross-sectional of the blade decreases the airflow resistance. Spire of the blade tilts up 3 degrees than the root part, conical air flow instead of cylinder one can directly cover a larger area and it makes airflows much more similar to natural intermittent wind. For our super ceiling fan , The powerful blades with aerodynamic design move much more indoor air,keeping the surface of the goods dry in wet season.
  Mixing the hotter air at roof level with cooler air at floor level to save heating cost in winter. Our HVLS Super ceiling fans are used in large facilities, warehouses, distribution centers, farms, large retail stores, sports arenas, stations, airports and other large buildings, become a ideal choice for ventilation, cooling and dehumidification of large indoor place.     Advantages   1)High efficient air flow   2)Strengthen the air cycle effectively   3)Low cost and free maintenance   4)Provide cool air flow in summer and hot air cycle in winter   5)Large application area   6)Propeller blades guarantee safety       Environmental Protection   1)Very low enery consumption   2)Provide natural ventilation and lower the temperature effectively   3)Refresh the air continuosly     Specification
