Product Description

24 FT Large Industrial Ceiling Fan for Factory Ventilation and Cooling with Aluminum Blades

 

Function of the fan:
1)ventilation
The fan improve air exchange in an entire space, it's perfect streamlined design can produces 2-3m/s speed three-dimensional wind, and makes you feel like enjoying the natural breeze system.It promotes the dispersion of smoke, moisture, carbon dioxide and poor air with high specific gravity.So as to improve the quality of working area, create healthy, dry and safe working environment, improve working efficiency.
2)convenience
It is convenience to be operated, control system adopts the latest poleless frequency converter control system.besides of convenience operation, the humanized operation interface also allows you enjoy the beauty of electronic and mechanic achieve the life.

  1. Dehumidification

Because it can produce large air volume, effectively promote air circulation, so that the moisture is well dispersed, greatly reducing the probability of problems such as bedbugs, fungi and so on.
4)beautiful and durable
After complex surface treatment,the product can avoid the pain of period cleaning,the cost-performance ratio is the highest,the life of each fan can reach more than10 years.

  1. energy saving

The rated power of the motor on the fan is 1.5KW,each fan can cover 1000 square meter working area,8 hours per day, is just 10 degree power energy consumption,compared to typical small fans and high power consumption air condition, large industrial ceiling fan can be called model of energy saving, can greatly reduce your operation cost.

Technical requirements for key components
    1,  Blade: the blade of the fan is designed based on aerodynamics technology. It's extrusion formed and made of AI-Mg alloy No.6061 metal material.and passed T6 heat treatment. The surface of the blade is also passed Anti-corrosive treatment of abrasive oxidation. Each piece of bale includes three reinforced tendons and two isolation reinforced cavity, wide(W) 182mm, Height(H) 23mm,the thinnest part is 2mm, and the thickest part of connection area is 5mm( it's shape and simulation will be shown in coming pages ) ,the strength of 6061 T6 heat treated AI-Mg alloy material is much higher than 50XX series AI-Mg alloy material in our industry. Below table shows you mechanical properties comparison data(test report attached).

1, Chassis structure; integrative chassis design compared to other brands has stronger strength.it resolves the influence of instantaneous impact, it is machined via hot forging,laser cutting,CNC machining as well as Anti-corrosive treatment.
2 , motor,customized for large industrial ceiling fans. Its inner bearing is SKF brand imported from Sweden,the noise value of the whole equipment is less than 60dB,Super-high strength gear with input stage, 2 module, output stage, 3 module, large module and fine grinding process, 40mm strengthened trapezoidal axle outlet structure, SKF enlarged oil seal from Sweden, high-grade synthetic lubricant in British Roadster is lifelong oil-free and maintenance-free, and the motor adopts German H-class insulation grade.
3, Control system: Poleless frequency conversion control system uses Taiwan Shilin custom frequency converter (with industry standard certification), the circuit board interior adopts dust-proof and moisture-proof treatment, built-in Schneider air circuit breaker, overload and leakage protection, accidental automatic power failure and alarm output, alarm code intuitive detection of circuit failure, network RS485 communication can be used. Access to Industrial 4.0 Network, Anti-EMI, Dust and Waterproof IP66 Protection Level.
4,  Main frame: Q345B high strength structural steel is treated by laser - bending - full welding - plastic spraying and rust prevention. The shield adopts stainless steel material heat dissipation guide hole design to prevent motor from overheating, the upper part adopts row hole design (waist hole design does not have anti-skid function) adjustable installation, the lower part adopts transverse longitudinal two-way adjustable horizontal universal joint (only transverse one-way adjustment can not fully adjust the level in the industry), and the lower part is coupling. Structural design of interference and anti-dropping device

5.  Safety components: all connecting bolts are high strength bolts greater than 8.8 grade, high strength anti-skid nuts, anti-loosening thread glue, anti-loosening turnbuckle screw tension stable fan, part of the structure uses alloy steel bolts with high strength fastening thread glue, 4 pieces of 8 mm anti-rust plastic wrapped wire rope cable,plus anti-falling ring installed.
