Carbon dioxide removal from the Space Station Freedom atmosphere is an essential part of the crew's life support. Freedom must utilize carbon dioxide removal systems to prevent crew asphyxiation. This paper describes the design and development of the blower selected to operate as an essential part of the carbon dioxide removal assembly (CDRA) system. The blower drives the process air through the CDRA, enabling the carbon dioxide laden air to contact the absorbing material. Multiple-speed blower operation is utilized to optimize carbon dioxide removal. A mixed-flow blower was selected as the optimum design to meet the CDRA application requirements. The prime reasons for this selection are the unit's low weight, small size, and outstanding efficiency. In addition, the blower unit is equipped with air bearings for extremely long life.
