Protective respirator with air distributor - has collapsible filter to reduce vol of respirator air preparation and distributor chamber, when not used

摘要

The respirator is packed in a flat container (1), when not in use. When required for use the hood (10) is pulled out of the container, with a sealing ring (9) fitting around the wearer's nose, mouth and chin. The respirator has a filter (3) for the air cleaning. When the respirator is not in use, the filter is compressed in concertina fashion. When in use, the cover (2) is pushed outwards by a spring (22) so that the volu. of the air distributor chamber is increased and the filter is extended in the axial direction. USE/ADVANTAGE - For aircraft and other confined spaces, with compact and reliable design.
