    Patent number: 10632330
    Abstract: An air delivery hose (10) has a CBRN resistant outer butyl rubber layer (12) convolute over a metal wire reinforced thermoplastic polyurethane inner hose (14). A combination unit respirator (20) has an air delivery hose (10, 10?) with a proximal end (22) with a three position lockable switch (40) that allows selection of APR, PAPR or SCBA modes, and a distal end (24) with a compact demand valve (30) responsive to the switch position.
