MSA Air-Line Systems Type C Supplied-Air Respirators, commonly called air-line respirators, provide long-duration respiratory protection. Systems generally consist of a full- or half-mask facepiece connected by air-supply hose to an air source. When connected, respirators deliver respirable air to users. This guide is designed to aid in understanding specific pressure-demand and constant flow air-line systems from air source to respirator. Complete air-line kits consisting of frequently-ordered systems for ease of ordering are listed as well. Type C Supplied-Air Respirators are approved by the...

Pressure-Demand System Optional locking quick-disconnects Sealing tape required on all pipe threads. Begin at second thread and wrap 1 to 1½ turns clockwise. * 2400 psig cascade system Select 1 outlet connection: E1, E2 or E3 Note: DO NOT use teflon sealing tape on straight threaded connections with O-ring seals. Note: Cascade cylinders are not normally used with constant flow systems due to excessive air usage—1 large (300- cu-ft) cylinder would last 1 working person only about 15 minutes. Therefore, using cascade cylinders with pressure-demand systems is recommended. Pressure Demand System...
