Is the fan two way? Can it be run in reverse so intake as needed and outlet as needed? I note it's AC so I suspect the answer to be no but would love if someone could let me know.
The fan is unidirectional, but it needs to be manually reversed to turn the original air inlet into an air outlet.

What happens if air passes through the device at 80 degrees Celsius. I want an urgent answer!
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.
