Air Revitalization Unit for Sealed Survival Shelters
Abstract
An air revitalization unit for use with sealed survival shelters without an external power supply was developed. The unit is capable of supplying oxygen to and removing carbon dioxide and odors from a 100-man personnel shelter for a 24-hour period. The system utilizes (1) a dry chemical absorbent (Baralyme) for carbon dioxide removal, (2) pressure cylinders for the oxygen supply, (3) an activated charcoal filter to remove odors, and (4) a battery-powered fan for air circulation. A prototype unit was designed, fabricated, and tested. Following tests of individual components, a 24-hour continuous test of the unit was completed. In general, the test results for the chemical, mechanical, and structural aspects of the air revitalization unit were affirmative. A similar assessment cannot be made for the human element inherently involved with the operation of the unit.
