When choosing and purchasing large industrial fans, users will inevitably be confused. They do not know which one to choose. Besides the performance requirements, safety and noise are also important for a good industrial windstorm. Firstly, there are five safety standards for large industrial fans.

 

1. See if the motor head and the whole part of the machine will jitter in low and medium speed gear, especially in high speed gear.

 

2. Look at the heat of industrial fan motor front shell sensed by hand or other devices after a long time of high-speed rotation (at least 1 hour later). If it feels very hot, it shows that the thermal performance of the industrial fan motor is not good.

 

3. Look at the speed, power, air volume, noise and other parameters (the speed, power, air volume and noise of industrial fans are proportional, that is to say, the higher the speed of industrial fans, the greater the power, the larger the air volume, the greater the noise, the better the cooling effect of local ventilation and cooling).

 

4. See if there is intermittent pause when swinging the head around at high speed, and if the head is not in place.

 

5. The industrial fan with big palm is designed with new mortise and tenon structure connection mode, which has the function of real collision avoidance.
