First, the working principle of the bathroom exhaust fan

In the process of exhausting air from the exhaust fan, the indoor air pressure will drop, the indoor air will become thinner, forming a negative pressure area, and the air will flow into the room due to the compensation of the air pressure difference. In the practical application of industrial plants, the exhaust fans are usually centrally installed on one side of the factory building, the air inlet is on the other side of the factory building, and the air flows from the air inlet to the exhaust fan to form convection blowing.

Second, the bathroom exhaust fan installation method

Bathroom exhaust fan installation method

1. Ceiling exhaust fan

The ceiling-mounted exhaust fan has a good appearance and can be installed on the ceiling of the bathroom. The duct of this type of ventilation fan is short, so it is necessary to purchase a ventilation duct that matches the chimney during installation.

2. Wall-mounted exhaust fan

The wall-mounted exhaust fan is small and can be mounted on the wall. However, due to the narrow cross-section of the air outlet, the ventilation force is weak, so it is only suitable for installation in a bathroom with a small area.

Bathroom exhaust fan installation method – window exhaust fan

3. Window exhaust fan

The window-type exhaust fan is different from the first two. It has a single and two-way operation mode, which can not only discharge the indoor air but also replenish the outdoor fresh air into the room. Therefore, the window-type exhaust fan has a wider application range and better effect. good.
