Product Description

24 FT Large Industrial Ceiling Fan 6 Blades

 

working principle :
Large ceiling fan is a series of products special developed for energy saving,working environment improvement. As we all know,refrigeration is not the only way to achieve the effect of cooling and comfort. The area of a fan could blow is determined by the diameter dimension of it, but has nothing to do with its speed.therefore, the industrial fan with large diameter and low speed combines all these characteristics . 
After years deeply research and exploration,by integrating oversea advanced aeronautic technology,we Dai sen developed a kind of propeller blades with outstanding performance,it conforms continuous and silent breeze by slowly rotation.The large volume of airflow generated by its unique and high efficient blades push down,thus a nearly perfect propeller exhaust is constructed.      
It pushes large volume of airflow to the ground,and constructed certain high level airflow moving horizontally,thus generates a overall air circulation.The advantage is overall ground coverage and three-dimensional circulation of air. 
The speed of wind generated by"Large industrial ceiling fan"is about 1-3m/s,completely calculated according to the best feeling of cooling when the airflow pass through human skin.too strong airflow makes people feel irritable,a sense of being blown directly,too high speed of airflow also makes people dizzy,only the through the evaporation of skin combines of breeze speed,can beautifies people's feeling of cooling.

Key component configuration


drive device 

Fengshen series fan adopts Taiwan/German gearbox motor
Fengxing series adopts the industry's first non carbon brush, large torque, DC drive motor, replacing the traditional motor speed reducer, realizing high integration, improving reliability and transmission efficiency
control device
Fengshen series fan adopts Taiwan / Germany brand inverter stepless speed change (optional explosion-proof controller) to configure circuit breaker overcurrent overload protection, cooling fan and other components

Fengxing series fan adopts a special brush free controller
fan blade 

The material of the fan blade adopts magnesium aluminum alloy T6 treatment, corrosion resistance, high strength, high toughness
Advanced fluid simulation software CFD simulation and wind tunnel test, in line with aerodynamic anti fatigue;
With the function of delay start, the load and impact of the motor are greatly reduced, and the service life is longer

24 FT Large Industrial Ceiling Fan 6 Blades

Structure components

The structural parts are formed by Q235B laser, bending the stiffener structure, and the thickest part is 8mm.
Alloy steel high strength bolts and anti-skid nuts are used for the bolts.
Steel wire rope and turnbuckle tension structure to stabilize the fan against falling
The integrated chassis can prevent the risk of fracture, the coupling anti falling structure can avoid screw defects, the chassis can be dropped, the hole arrangement design of plywood structure can prevent sliding, the adjustable structure is suitable for any installation conditions, and the arc-shaped adjustable waist hole can be adjusted to ensure the plane level of blade chassis
