通風是一種換氣設備，它是用機械或自然的方法向室內空間送入足夠的新鮮空氣，同時把室內不符合衛生要求的污濁空氣排出，使室內空氣滿足衛生要求和生產過程需要，通風管道設備有著十分廣泛的使用范圍。下面小編就來為大家介紹一下通風管道設備安裝的規范細則以及常見問題。

Ventilation is a kind of ventilating equipment, it uses mechanical or natural methods to send enough fresh air to the indoor space, and at the same time, it discharges the dirty air that does not meet the sanitary requirements, so that the indoor air can meet the sanitary requirements and the needs of the production process. The ventilation pipe equipment has a very wide range of use. The following small edition will introduce the specification details and common problems of the installation of ventilation pipeline equipment for you.

當今，建筑中完成通風工作的各項設施，統稱通風管道設備。通風管道設備分排風扇，換氣扇，風機等，又分工業用及家用二種。而風機又分高、中、低、負壓等。

Nowadays, the ventilation facilities in the building are collectively referred to as ventilation pipe equipment. The ventilation duct equipment is divided into exhaust fan, ventilation fan, fan, etc., and is divided into industrial and household two kinds. And the fan is divided into high, medium, low, negative pressure and so on.
