PremAire® cadet escape responder respirators can be used with a wide range of MSA air supply hose that can be interconnected up to a maximum length of 300 ft. A maximum of 12 sections of air supply hose may be used in making up the maximum 300 ft working length of hose. Each section of coiled hose is considered to be 50 ft in L (maximum 6 sections). MSA air supply hoses have various temperature limitations. These accessories help ensure proper air quality and deliverability when used with MSA constant flow airline systems. Filters remove 99% (minimum) of >0.3 micron particulate for up to 1000 hr of use. Air supply hoses deliver respirable air from 8 to 5 ft in temperatures from -25 deg F to 212 deg F (depending on type). And cylinder cascade systems deliver single source air to one or more workers.
