1. The ceiling exhaust fan has a good appearance and can be installed on the ceiling of the bathroom. The pipe of this ventilator is short, so it is necessary to buy a ventilation pipe matching with the pipe when installing.

2. The wall-mounted exhaust fan is small in size and can be embedded above the wall. However, due to the narrow cross section of its exhaust port, the air exchange intensity is weak, so it is only suitable for installation in a small bathroom.

3. The window exhaust fan is different from the first two. It has one-way and two-way operation modes, which can not only exhaust indoor air, but also replenish outdoor fresh air indoors. Therefore, the window exhaust fan has a wider application range and better effect.

to determine whether to install it on the ceiling or the wall, choose different models of exhaust fans according to different installation positions. The exhaust fans installed on the aluminum gusset ceiling are all equipped with metal fasteners matching with the ceiling keel, which is very convenient to install; For the exhaust fan installed on the wooden keel ceiling, just connect the exhaust pipe and tighten the exhaust fan panel with wooden screws. If you want to install it on the external wall of the bathroom, you should first open a hole in the wall, and the aperture should be determined according to the diameter of the exhaust fan outlet you choose; Or installed on the wall of the exhaust duct reserved in the bathroom, it needs to be equipped with a check valve to prevent the smell of other people's homes from coming to your home. Generally, the wall installation needs to be punched with an impact electric drill and fixed with expansion screws.

2. Precautions for installing the exhaust fan in the bathroom

1. The ventilator should be placed horizontally. Be careful not to tilt when using it. When using it, check whether the power supply of the socket is consistent with the parameters on the nameplate of the fan.

2. Try to be close to the original air duct. Principle of shortest pipeline.

3. Try to be close to the position where odor and moisture are generated. The highest efficiency principle.

4, should not be installed directly above the shower, otherwise the airflow will make the body feel uncomfortable, and when the temperature is low, the heat loss will be large.

5, combined with ceiling modeling, block, lighting, etc., aesthetic considerations.
