DIVING TECHNOLOGY SYSTEM TECHNOLOGY SERVICES
Users of the Dräger PSS® BG 4
closed-circuit breathing apparatus are
supplied with breathing air for up to
four hours so that they can operate
even in atmospheres containing little
oxygen and/or pollutants. The slight
positive pressure in the breathing circuit
protects the user against the ingress of
containing pollutants into the closed
breathing circuit. The carbon dioxide
contained in the exhaled air is bound by
the CO absorber. At the same time, the
2
breathing air is enriched with oxygen from
the oxygen cylinder. Before the
regenerated air is re-breathed, it streams
through a breathing air cooler, thus making
the Dräger PSS® BG 4 ideal for long-term
use in toxic environments.
Features
The Dräger PSS® BG 4 offers numerous
features for safer use.
- DrägerMan Bodyguard® II
The electronic signal and warning unit
delivers and stores vital information thus
increasing safety during use. It supplies
information quickly and clearly, visually
and acoustically, in analog and digital
format.
DrägerMan Bodyguard® II can be
connected to the Telemetry System
"Merlin" for transmitting the vital data.
- Anti-vibration strap
Ensures that your closed-circuit breathing
apparatus can be transported safely in
motor vehicles.
- Optimum wearing comfort
The ergonomically shaped carrying
frame, the low weight and the improved
harness ensure considerable freedom of
movement and less physical effort.
- High breathing comfort
Due to the slight positive pressure in
the breathing circuit, the spring-loaded
breathing bag protects the user against
toxic ambient gases, for instance if there
is a leak in the face seal. To reduce the
temperature of the inhaled air, thus
reducing the physical burden for the user,
the breathing air cooler can additionally
be filled with ice.
- CO
absorber

The streamlined CO absorber with
2
integrated dust filter is available as a gray
disposable absorber or as a translucent
refillable cartridge, entirely as you require.
