Nature Wind Series(Gear motor):
It's our pleasure to introduce the HVLS(High Volume -Low Speed)fan to you ---Nature wind Series large energy--saving fan with a diameter up to 7.3M.
Bigfans Airfoil Blades,Which are streamlined ,are developed with the advanced technologies and the principle of aerodynamics.Just with a power of 1.5KW or less,the blades are able to drive a mass of air and then produce a large scale of natural wind,which leads to the double functions of ventilation and temperature cooling.Compared with the traditional HVAC conditioners and small high - speed air blower,the fan has superior advantages in application,and is the ideal solution to ventilate and cool the air in large area.


Efficient

One 24ft Bigfans HVLS fan can replace 380 industrial fans or 170 evaporative coolers for an unbelivable 90% savings in power consumption while increasing the amount of air circulation.

Air Flow

Bigfans HVLS Fans moves large volumes of air in a conical manner at low speed over large areas.The fan blade produce a massive column of air that flows down the floor and out in all direction.creating a deep "horizontal floor jet "that ultimately circulates air vertically and gets drawn back to the top of the fan .
