Your building is a common flue, check the movable baffle of your range hood, it should be closed in normal times, which can prevent the backflow of oil fumes. >>>More
The following can be used for reference: before the installation of the range hood, first, to determine the installation location, and second, to grasp the installation time. >>>More
The exhaust pipe of the range hood is from the ceiling space through the wall to exhaust smoke, if the exhaust pipe is intact the mouse is not able to enter the ceiling space, it is estimated that the mouse will bite through the aluminum corrugated pipe into the ceiling, you can replace the aluminum corrugated pipe with a white iron pipe mouse can not bite through the ceiling.
From the ventilation and exhaust method to the type of motor and fan blades, it is different, just like the difference between a large truck and a small car, but the basic principle and composition are the same, but in fact they are completely different things.
