20FT 6.1M Hot Sell Big Ceiling Fan Low Noisy HVLS Fan For Workshop
The width of the blade is gradually narrow along the radial, on the contrary the velocity increases, improve the equilibrium in generating the airflow along the whole blade; So it is better performance than blade with the same width along the radial.
Motor System---imported Germany motor
1. Low backlash assembly process and gear grinding technique, lower noise
2. Strength the bearing frame structure, increase oil seal and strength the motor structure with trapezoidal shaft structure, higher safety
3. Shell top Omala S4 Long life synthetic gear oil
Control system
Introducing importde high quality electric cabinet, energy efficientcy integated with security potection.
Using Fluorocarbon Iacquer box configuration Schneider load switch,ventilating port.
with over current and overvoltage/under votage/open phase/over load/overheat protection,make it antomatic power-off when have an accident.
Fan Blades
1. The material of the fan blade adopts magnesium aluminum alloy T6 treatment, corrosion resistance, high strength, high toughness
2. Advanced fluid simulation software CFD simulation and wind tunnel test, in line with aerodynamic anti fatigue;
3. With the function of delay start, the load and impact of the motor are greatly reduced, and the service life is longer
Hub
Using integrated aluminum magnesium alloy and made by precise cutting technology to ensure the consistency of the chassis as well as seurity.

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 is as energy efficient as a system with HVLS industrial fans. In fact, research shows that businesses can reduce or eliminate the use of expensive air conditioning with solutions optimized for oversized ceiling fans. Some oversized ceiling fan suppliers provide his 3D thermodynamic model of a customer's room, proving the effectiveness of oversized ceiling fans as a cost-effective air cooling system.
Features
※Energy saving: The maximum power of D-500A extra large ceiling fan is 700 watts.
※Big wind: D-500A has a maximum wind volume of 10000m³/min.
※Natural airflow: D-500A Big HVLS Fan can form wind like natural airflow.
※Lightweight fan main body: The total weight of D-500A (main body) is 17kg.
※Built-in PMSM motor: D-500A adopts no PMSM motor and gear box.
※Stepless speed regulation: Our controller is perfectly matched with the fan, and the fan speed can be adjusted steplessly.
