Mainstream Engineering Awarded Contract from Chemical and Biological Defense to Continue Development of Enhanced SCBA Systems
Currently, SCBA systems use an O2 cylinder, an adsorption-based CO2 scrubber, and a positive-pressure breathing loop to provide an isolated breathing source. Removal of CO2 by adsorption adds heat and moisture to the breathing gas (in addition to the amount generated by the user), which is uncomfortable and potentially dangerous. The physiological burden on the user is increased, which decreases the performance and capacity of the SCBA system. Mainstream’s technology is being developed to eliminate the scrubber with a zero-heat moisture-removing CO2 removal system. A complete micro-sensor and controller will be developed for continuous monitoring of breathing and optimized control over system components.
Mainstream plans to integrate the new CO2 removal technology with smart micro-sensors and controls in a demonstration system. Performance enhancements and air quality improvements will determine the size, weight, and power of the drop-in prototype system for SCBA respiratory protection equipment. After successful demonstration under operational conditions, this technology will be transitioned to product development and manufacturing.
