The Stopping and Ranges of Ions in Solids

A system for providing a large volume flow of sterilized air through a serviced medical service facility for significantly reducing sources of airborne contamination in the facility comprises a closed circulation loop connected between an output plenum of the medical service facility and an input plenum of the medical service facility. A compressor in the closed collection loop imparts flow energy to the air circulating in the closed circulation loop and simultaneously raises the temperature of that air. The compressed, heated air is maintained at sterilizing temperature for a sufficient time to achieve substantially complete sterilization and then flowed to the medical service facility.
