How to Choose a Ventilation Fan for Your Industry Cabinet

There are many different kinds of ventilation fans for industrial cabinets, so how to choose a perfect fan for the cabinet? We can consider the following aspects:

1. According to the different physical and chemical properties of the gas transported by the fan, choose a fan for different purposes. An explosion-proof ventilator fan can be selected for flammable and explosive environment; Those that discharge dust or pulverized coal should choose a dust exhaust or pulverized coal fan, and anti-corrosion fan for transporting corrosive gases; When transporting high temperature gas, a high temperature fan should be selected.

2. If the diameter of the selected fan impeller is much larger than that of the original fan, in order to use the original motor shaft, bearings and supports, etc., the motor startup time, the strength of the original fan parts and the critical speed of the bearing must be checked.

3. For selecting a centrifugal fan, when the power of the motor is less than 75KW, it is not necessary to install a valve for starting only. When the centrifugal blower fan is selected to discharge high temperature flue gas or air, a valve for starting should be set to prevent overload during cold operation.

4. When choosing a ventilation fan, try to avoid using fans to work in parallel or in series. When it is unavoidable, fans of the same type and performance should be selected to work together. When a series connection is used, there should be a certain pipeline connection between the first-stage fan and the second-stage fan.

5. The most important is that the selected fans should consider the environment of the original equipment, suitable and easy for installation, and safe operation.
