ABSTRACT:
This invention relates to apparatus for removing nitrogen from air. A compressor forces the air into a bed which is capable of adsorbing nitrogen from the air and also removes gas from the bed by suction. The cylinder of the compressor communicates directly with the bed through a pipe which permits gas to flow freely in both directions and the bed communicates with the chamber for collecting the gaseous mixture from which the nitrogen has been removed. That chamber is connected to an outlet pump via a first controllable outlet valve while the end of the cylinder which is in direct communication with the bed is provided with a second controllable outlet valve. The nitrogen free mixture passes out through the first controllable outlet valve and the nitrogen passes out through the second outlet valve.
