Abstract
A system and method is disclosed for providing a continuous supply of clean air at a desired temperature to the crew compartment of a vehicle when in an environment contaminated by nuclear, biological or chemical warfare agents. Exhaust gases from the vehicle's engine is used to drive a first compressor which directs compressed and heated air to a precooler, an aftercooler, a heat exchanger and a pressure swing adsorption system which removes all known contaminates from the air providing clean output air. The clean air is expanded and cooled by a turboexpander which drives a secondary compressor and a coolant air compressor. A temperature controlled circuit is provided to control the temperature of the air throughout the circuit and in the crew compartment at the desired levels.
