外部吸风罩位于烟源附近，靠近吸烟口的吸风将烟吸进罩内。对生产运行影响小，安装维护方便，但增加了周围空气的吸入量，排风量大，效率低，对有害物质的控制能力差。主要用于因技术要求或操作条件限制，污染物无法密封的场合。
The external suction hood is located near the smoke source, and the suction close to the smoking port will suck the smoke into the hood. It has little influence on production and operation, convenient installation and maintenance, but it increases the intake of surrounding air, large exhaust air volume, low efficiency and poor control ability for harmful substances. It is mainly used in the situation where pollutants cannot be sealed due to technical requirements or operating conditions.
