There are generally several types of roof fans commonly seen in the market nowadays, and the types are good for statistical analysis. This type of fan is installed on the roof, so it has the advantage of saving indoor space compared to some fans assembled indoors. But no matter what kind of machinery and equipment, there will also be some difficulties. If the temperature of the roof fan is too high, what is usually the cause?

When the roof fan operates at room temperature, there may be some phenomenon of high temperature, but it is only within the normal range. This is because the parts of the machine itself rub against each other, generating heat and causing the overall body temperature to be high. However, not all situations where the temperature is too high are normal. The main factors that cause the body temperature of the fan equipment to exceed the standard value are as follows:

The first type: motor phase failure or incorrect wiring.

The second type: excessive friction resistance in the system software or unscientific selection of fans can cause the motor to operate under overload, mainly due to excessive resistance coefficient in the pipeline network or failure to open the pipeline index gate valve.

The third type: low pressure of switch mode power supply.

Fourth type: Damaged motor bearings with small assembly clearance that does not comply with regulations.
