②根据通风机输送气体的物理、化学性质的不同,选择不同用途的通风机。如输送有爆炸和易燃气体的应选防爆通风机,确定风机所需防爆等级要求;排尘或输送煤粉的应选择排尘或煤粉通风机;输送有腐蚀性气体的应选择防腐通风机,确定防腐材质用玻璃钢还是PP等;在高温场合下工作或输送高温气体的应选择高温通风机,并且了解环境温度以及输送气体温度等。

③在通风机选择性能图表上查得有二种以上的通风机可供选择时,应优先选择效率较高、机号较小、调节范围较大的一种,当然还可以性价比方面来比较,权衡利弊而决定。

④如果选定的风机叶轮直径较原有风机的叶轮直径偏大很多时,为了利用原有电动机轴、轴承及支座等,必须对电动机启动时间、风机原有部件的强度及轴的临界转速等进行核算。
