Product description

The wind blown from large industrial ceiling fan feels like natural breeze system,the wind speed is just the best cool feeling of human skin. Personnel can feel the temperature difference 5-8 degree, provide personnel a suitable working environment in hot summer,therefore improve the production efficiency.
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.

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.

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.
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.

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).
