Translation of "concentrator" into Chinese

But so in here when there's electricity, the oxygen concentrator takes in room air.

但是当有电的时候 氧气集中器就采入室内空气

Neither concentrators nor cylinders are well suited to every situation, but a simple options assessment can determine which is better in each setting.

使用氧气浓缩器或氧气瓶应视当地情况而定,而进行简单的方案评估可作出更好的决定。
