Numerous optimisations and new accessories increase safety and durability and improve the ease of servicing once again. The modifications are available individually or as a practical retrofit set upon request.
Robust, trusted and reliable
The Dräger PSS® BG 4 is a closed-circuit breathing apparatus which is independent of the surrounding air and particularly suited for long-term assignments in a toxic environment. Soda lime absorbs the carbon dioxide in the exhaled air and oxygen is constantly added and not guided outside - such as in breathing apparatus with pressure gauge - but kept within the circuit. Depending on job performance, the duration of use is up to four hours. For oxygen supply, compressed oxygen is used.
High-performance soda lime
Drägersorb 400 has been especially designed for the absorption of CO2 in closed-circuit breathing apparatus. It contributes significantly to the long-term safeguarding of performance capability, especially under the expected conditions of use of the Dräger PSS BG 4 plus. Drägersorb 400 is characterised by a very high abrasion resistance and can therefore be used in the apparatus for 6 months or, if stored in the vehicle, over a distance of 500 kilometres.
The ergonomically shaped carrying plate, the low weight and the perfectly fitted harness offer greater freedom of movement with less effort. The practical breathing hose routing across the shoulders ensures the optimum balance of the apparatus on the back of its wearer.
The Dräger PSS® BG 4 can be assembled and disassembled quickly and conveniently without tools.

The breathing apparatus is equipped with the fully electronic warning and signal unit Bodyguard® II.
