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
★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
Comparison of three refrigeration methods in 1000 square meter plant
| Refrigeration mode | Quantity | Power/unit | Tall power | General comparison |
| Central air conditioner | 1 | 80KW | 80KW | The walls and doors and windows of the plant are required to be insulated. The cost of one-time investment of the equipment is high, and the maintenance cost of replacing the filter element and adding refrigerant is high |
| Traditional industrial fan | 40 | 0.3KW | 12KW | The installation of traditional wall fans is limited by walls and columns. The power lines of floor fans are scattered, which has potential safety hazards. It is not safe for the hair of staff members to be mixed into the fan blades, which occupies a small space and covers a short service life |
| 7.3M large industrial ceiling fan | 1 | 1.5KW | 1.5KW | Large coverage area, long service life, low maintenance cost, installation does not occupy the workshop space, safety and environmental protection |
The energy consumption of large industrial ceiling fan is about 1 / 50 of that of central air conditioner and 1 / 10 of that of traditional industrial wall fan
***Suitable places of installation: Any high enough structure of factory,sport center,logistic place,car repair workshops,supermarket, airport,package workshop,animal breading industry,any kinds of hall,as well as fitness center etc.
***Height of installation: "Fengshen" series products for 6 meters to 20 meters height.
"Fengxing" series products for 3 meters to 6 meters height.
***Solutions for the three main kinds of installation structures as above shown pictures.
There are various forms of building structures. We provide you with the installation methods of three common structures (right figure):
