A design of a self-contained Smoke and Contaminant Removal System (SCRS) and its capabilities in removing airborne particulates and toxic gases generated from a Space Station fire are presented. Based on potential fire scenarios, an SCRS has been sized to weigh 52 lb, consume 50 watts and occupy less than 3 ft3. The replaceable filter/sorbent beds provide the SCRS with the capability of handling multiple contaminant challenges.
The SCRS will reduce the necessity to compromise mission objectives by changing out Space Station air. The SCRS option provides the crew with the added flexibility of restoring and maintaining the quality of the habitable environment.
