2 Description
2.1 Product overview
The Dräger PSS®5000 Series is a self contained breathing apparatus
(SCBA) that uses an open-circuit breathing system. The series is
compatible with a wide range of compressed-air cylinders, face masks and
lung demand valves (e.g. FPS 7000 and Panorama Nova face masks, PSS
Series lung demand valves, and steel or composite cylinders).
The apparatus can also be fitted with a multi-function electronic monitoring
system (e.g. Bodyguard®7000). Refer to the relevant Instructions for Use
for the description, operation and testing of electronic systems.
2.2 Feature description
The carrying system has a carbon-composite backplate, with adjustable
shoulder straps and waist belt connected using quick release connectors.
A waist pad (Fig 1, Item 6) connected at a flexible joint compensates for
the twisting and bending of the user. Cylinder mounting systems include a
single cylinder strap (2) or a universal cylinder strap for use with twin
cylinders.
The apparatus uses the Dräger high-performance pressure reducer (4)
that reduces cylinder pressure and supplies breathing air through a
medium-pressure hose (5) and coupling (1) to the attached lung demand
valve. A dual-pressure hose (3) supplies air to the whistle when it is
activated, and has an internal capillary tube that supplies high-pressure air
from the cylinder to the gauge. Air hoses and modular components of the
monitoring system are integrated into the backplate to prevent snagging
and enhance component protection.
Compressed air cylinders, lung demand valves and face masks
The Dräger PSS 5000 Series is compatible with steel or composite
material cylinders of 4 to 9 litre capacities, and 200 or 300 bar pressure.
Full descriptions and user instructions are contained in separate
instructions supplied with the cylinder, mask or lung demand valve.
2.3 Intended use
The Dräger PSS 5000 Series breathing apparatus, when fitted with a
cylinder, lung demand valve and face mask, is intended for use by
emergency services and in industrial applications where a high level of
respiratory protection is required. The assembled breathing apparatus
provides the wearer with respiratory protection for working in contaminated
or oxygen-deficient conditions, and is suitable for fire fighting.
The cylinder, lung demand valve, face mask and other accessories used
with this product must be certified Dräger components, assembled in an
approved configuration. Contact Dräger for further information.
Use in potentially explosive atmospheres
The PSS 5000 Series is type tested as suitable for use in potentially
explosive atmospheres. Electronic sub-assemblies are ATEX certified.
All combinations are suitable for use in hazardous areas up to and
including zone 0 and zone 20.
