A breadboard model of the self-contained Collective Protector Unit was completed. Initial pressure drop is under 10 in. water at 400 cfm. Motor-blower tests show problems with surge, though otherwise appear usable. Development continued on a filter retaining mechanism, deep fording sealing device, particulate filters and gas filters. Short term value analysis studies were completed on all CPU components. Author
