Abstract
A system and method provides a continuous supply of clean air at a desired temperature to the crew members of a combat vehicle when in an environment contaminated by nuclear, biological or chemical warfare agents. The contaminated air is initially compressed by energy received from the exhaust gases from a combustion power unit of the vehicle, the initially compressed air is then cooled to increase its density and is then compressed and cooled a second time before being passed through a pressure swing adsorbent system which continuously removes all known contaminants from the air, and is then expanded and changed in temperature to provide clean air at a desired temperature to personnel within the vehicle. The energy released from the air during expansion is used to compress the air the second time thereby providing a very energy efficient system.
