The ambient temperature of this product is -10~45 degrees Celsius. If the air passes through this duct fan at a temperature of 80 degrees Celsius, the following situations may occur: 1. High temperature air may reduce the efficiency of the fan. This is because high temperature will reduce the air density, thus affecting the air volume and air pressure of the fan. 2. The fan motor may overheat or even burn out when running in a high temperature environment.
