Breathing apparatus

This equipment is distinguished by being particularly compact and of flat design, with little weight. By using standard mask filters as filter media, which are not situated in the front, but on the back of the person carrying the equipment, and due to the special contamination protection by fitting the equipment under one's suit, the equipment can be used nearly universally. Its safety is increased by the air quantity warning device being provided by flow monitors with buzzers and by self-breathing of the equipment in case of faults. It also guarantees great manoeuvrability of the staff, a long operating period and does not cause any resistance to breathing. (orig./HP)
