1. Industrial fans run for a long time, the bearing inside the lack of lubricating oil led to noise, just need to drop lubricating oil can be solved. 2. At present, in order to save costs, some manufacturers of industrial fans in the market use cheap materials, and manufacturing technology is not up to standard, there has been "eccentric" phenomenon, fan operation for a period of time, "eccentric" more and more serious, gradually there will be noise, this need to buy their own industrial fans to identify. 3. During the long-term operation of the Fan, the damping pad between the Fan Blade and the blade handle appears to be worn, and there is a gap that generates noise. At this time, we only need to replace the damping pad and tighten the screws to solve the problem. 4. The higher the voltage of the industrial fan, the higher the speed, the greater the vibration, and the greater the noise. The component design of the fan also affects the noise level. At this point only consider the size of the wound core, Fan and frame design and accurate manufacture and balance. If there is still noise, you can contact the company, we will serve you wholeheartedly!
