"Lead" Industrial Fan

The new industrial large fan with high air volume and low speed has a safe diameter of 7.3 meters. It is developed and manufactured by using aerodynamic principle, which is safe, reliable and durable. It uses only 1.5KW motor to drive the airfoil fan to generate super large area simulated natural wind system, to accelerate the air circulation in large space, and to cool the body sensation in the covered area up to 5-6 degrees Celsius, to improve the working environment and to upgrade. Work efficiency, perfectly solve the problem of ventilation and cooling in large space.

  • Body cooling
  • Natural draft
  • Equilibrium
  • Dehumidification
  • Fan combination
  • Super coverage
  • Low energy


The natural breeze produced by the large industrial fan of Onfu blows on the human body, promotes the evaporation of sweat to take away heat, and makes the human body cool, bringing a cool feeling. Usually, this cooling sensation can reach 5-8 degrees Celsius. Bring comfortable experience of natural wind to human body. The three-dimensional natural breeze blown by large industrial fans is more comfortable because, on the one hand, the three-dimensional blowing of the human body makes the evaporation area of the human body reach the maximum. On the other hand, human beings have accumulated a kind experience of natural wind in nature, but when a natural breeze with variable wind speed blows, the human body will naturally feel extremely comfortable and cool.

Natural Ventilation and Improvement of Air Environment

In previous ventilation schemes, people often decide which products and quantity to use according to the number of ventilation in space. This is very obvious in small space. You can even see the steam in the bathroom drain out quickly with the operation of the abdominal pressure fan. But in the large enclosed space, the ventilation effect is not obvious: for example, the larger smoke, moisture, carbon dioxide, poor quality air, or concentrated at the bottom of the building, roof negative pressure fans on these corners of the air has no effect, but precisely the personnel and equipment are there. Large industrial fans will promote the mixing of air in the whole space. Smoke, moisture and fungi with unpleasant odor can be well dispersed, thus improving the air quality in the city and obtaining a healthy, dry and safe working environment.
      Including dairy farm, feeding farm, hatchery and so on. Good ventilation can improve air quality, dehumidify, remove odors, and reduce the incidence of livestock. Appropriate temperature can make livestock feel comfortable, stimulate the rapid growth of livestock, thereby improving the productivity of stocked livestock, and increase the production of poultry eggs, milk and meat.

In winter indoors, the hot air generated by air conditioning heating gathers on the top floor, while the ground temperature is moderate and low. Low-speed industrial energy-saving fans can slow the hot air from the roof to the ground, which can balance the indoor temperature and avoid energy consumption caused by uneven temperature.






If the ventilation and cooling conditions in buildings are poor, the quality of products may be reduced, and even a lot of losses and waste may be caused! In addition, some materials will become the first object of complaint once they are damped and deformed. To prevent air condensation, reduce bacteria and mildew, super industrial fans significantly enhance air flow and thus control air condensation on the ground or metal surface, can make your working environment more clean, dry, comfortable and safe. Drive out the birds that enter the room by mistake to ensure the internal sanitation of tall buildings.

Fan combination

The concept of fan-machine combination is especially suitable for all kinds of large indoor workplaces which pursue ventilation and cooling while maintaining the safety, beauty and investment of roof load-bearing. Without air conditioners, large fans can not handle the indoor temperature very well, and without large fans, when only using air conditioners, a large number of air supply pipes must be set up to hang in the center of the indoor house, which affects the aesthetics and building safety. Only the combination of fans can give consideration to both, so as to achieve the objectives of ventilation cooling, ventilation, economy, beauty and safety, and to the air in tall and large buildings. It is of great significance.


Basic characteristics:

1. The drawing shows a large-span steel structure workshop with heat source and high indoor temperature in summer. The diameter of the large industrial fan is 7.3 meters, and the air flow rate is 13,000 cubic meters/minute. The maximum air flow coverage area of each fan can reach 1000-1600 square meters depending on the installation height. The air flow can extend to the radius of the fan center at least 20 meters. The air flow speed is about 2-3 meters/second, the maximum speed is 53 rotations/minute, the motor power is 1.5 KW, frequency conversion drive, stepless. Speed regulation; The power of the air conditioner is 1.1KW, the maximum cold air volume is 18000 cubic meters/hour, which is installed on the outside wall of the workshop.

2. Large fan characteristics: large air volume, three-dimensional wind, large coverage area. Characteristics of evaporative air conditioner: fresh air supply, cooling, dust filtering, increasing oxygen content of indoor air and realizing positive pressure exhaust.

The reason why the super-large energy-saving fan can cover such a large area depends on the unique streamlined fan blade design, which can reduce the resistance to the minimum and convert the highest efficiency of electric energy into the kinetic energy of air. In addition, the airflow structure of the fan is different from that of the ordinary small fan. The small fan can only cover the range of the fan diameter, while the super-large energy-saving fan first pushes the airflow vertically to the ground, and then forms a 1-3 meter high airflow layer on the ground, thus forming a super-large coverage area not limited to the lower part of the super-large energy-saving fan. In an open space, a fan can cover even a very large area of 1400_.








Energy saving and environmental protection

The coverage area of a 7.3M diameter fan is equal to the coverage area of 50 0.75M small fans. For example, in a 9000 square metre factory building, in order to achieve full coverage effect, about 300 small fans are needed, while only 6 industrial energy-saving fans are needed. According to the use of 4 years, 8 months a year, 10 hours a day, a total of 10,000 hours of operation, 90,000 KW. h power consumption, 1080,000 KW. h small fans, energy saving 990,000 KW. h, energy saving 92%.

It can save more than 30% energy when used in conjunction with air conditioning.
