Product benefits

Modification: We listened to our customers and modified the new Dräger PSS BG 4 plus according to your requirements. Numerous optimizations 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 plus 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 characterized 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.
Wearing comfort: The ergonomically shaped carrying backplate, the low weight and the perfectly fitted harness offer more 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.
Easy maintenance: The Dräger PSS® BG 4 plus can be assembled and disassembled quickly and conveniently without tools.
Worldwide DrägerService®: The operational reliability of safety-related devices has become a key factor today. Devices must be ready for operation and fully functional for every assignment to guarantee maximum safety. The services provided by DrägerService® offer support for the safe and reliable operation of your devices and are available to you at any time.
All functions at a glance: The breathing apparatus is equipped with the fully electronic warning and signal unit Bodyguard®/Sentinel II. It provides the wearer with important information, such as cylinder pressure, remaining duration of use, or temperature during the assignment. The information is presented visually and acoustically. The data registered by Bodyguard®/Sentinel II can be transmitted to the Dräger PSS® Merlin monitoring panel in connection with an optional transmitter unit.

Drägersorb®

Drägersorb® 400 is a product of the series whose development was promoted in combination with the closed-circuit breathing apparatus. As a result, high-tech devices and absorbents were produced which are perfectly matched and correspond to the state of the art. Drägersorb® 400 is used to absorb acid gases, such as carbon dioxide (CO2), in closed or semi-closed circuit breathing apparatus, e.g. for mining.
