CIRCULATING DEVICE FOR CLOSED CIRCUIT RESPIRATORY SYSTEM.
Abstract
One type of circulating device for use in a closed circuit respiratory system is described. Circulation is required in a closed system to remove carbon dioxide, add oxygen, remove moisture, and cool recirculating gases. The device is a single-stage, centrifugal-type blower capable of discharging 12 CFM of oxygen against a back pressure of 25 inches of water. It is powered by a 28-volt D. C. motor. Power supply is a silver cell battery. Flow control is maintained electrically by a rheostat. (Author)
