There are three types of ventilation methods for ventilation fans: indoor, kitchen, and bathroom.
1. The bathroom generally has a small area, about 2-4 square meters, and can use an open ventilation fan of 150-200 millimeters.
2. The kitchen can choose to use a 250mm shielded ventilation fan. If a range hood is already installed in the kitchen, a ventilation fan can be omitted.
3. The bedroom and living room area is generally around 12-16 square meters, and a two-way ventilation fan of 250-300 millimeters is more suitable.
When making a selection, pay attention to the following points:
1. The ventilation fan has a novel appearance, with colors that coordinate with the room color. The plane is free of warping, the plastic parts are flat and smooth, the electroplated parts are bright, and there are no rust marks. The fan blades can rotate.
2. After power on, the fan blades rotate smoothly without any abnormal noise, and the air volume is high. Self blowing blinds have flexible and movable leaves. The linked shutter is sensitive to rotation on all sides. The bidirectional ventilation fan can convert freely. The temperature rise of the motor is not too high and the noise is low. The ventilation fan with speed regulation function has obvious speed regulation, and the capacitance motor is not more than 65%, and the cover plate type is not more than 80%.
