7.3m Big Hvls Fan Industrial Plant Big Ass Air Ceiling Fans

Product Description

7.3m Hvls Industrial Plant Big Ass Air Ceiling Fans Big Hvls Fan

Blade weight-light
Each blade 6.7KG,total weight for 5pcs 33.5KG.Smaller blades ,lighter weight, reducing the motor load and extend service life, low energy consumption.

Blade weight-heavy
Cross section width equal to the blades, Each blade 10KG,normal 6pcs or 8pcs.Heavy weight, large motor load, high energy consumption.

Blade and petiole -- full mortise and tenon connection
The convex petiole and concave buffer device are locked with bolts, each blade is riveted with buffer device by 16 rivets,forming the blade, buffer device and petiole as a whole, torque and shear less and less.

Blade weight-heavy
Cross section width equal to the blades, Each blade 10KG,normal 6pcs or 8pcs.Heavy weight, large motor load, high energy consumption.

Buffer device-Rubber mat
The rubber pad between mounting hole of buffer device and shaped inserts to achieve the flexible connection between petiole and chassis.Rubber mat absorb the most of vibration, improve the motor shaft work conditions, extend the life, more quieter

Buffer device-No
Vibration cannot be weakened, resulting petiole and blades loosen,heavy loading, high noise.

Wheel chassis-Integrated hub
Special-shaped mounting hole and inserts locked each other to prevent the blade from swinging

Wheel chassis structure-die cast
Gravity die-casting aluminum wheel chassis or separated wheel hub, low strength, poor fatigue resistance.

 Technical parameters 

​ How does it work 

The principle behind the extra large ceiling fan is to move a very large amount of air by using large-diameter fan blades rotating at a low speed to break up the stratified air layer. The low speed of the fan makes it more efficient to convert electrical energy into useful laminar flow, rather than generating wasteful turbulence and resistance at higher speeds-which ultimately only generates unwanted heat. These large blades move more air than their smaller ceiling fans, usually 5-20 times, and have the same cooling effect. No other cooling system can be as energy-efficient as a system using HVLS industrial fans. In fact, research shows that companies can reduce or even completely eliminate the use of expensive air conditioning systems through optimized extra large ceiling fan solutions. Some extra large ceiling fan vendors provide 3D thermodynamic models of customer rooms, which proves the effectiveness of extra large ceiling fan as a cost-effective air cooling system.

 Features
