Specially designed for todayís professional fire-fighter
Drager has led the way in the design of technically advanced respiratory
protection equipment for more than a century. Through continuous
product improvement and investment in technology, we have developed a
range of products which takes compressed air breathing equipment to a
new dimension of personal safety.
PSS 90 is the newest addition to Dragerís family of Personal Safety
Systems. Fitted with Dragerís high performance advanced ĎPlusí
pneumatics, this self contained breathing apparatus comes with the new
PSS enhanced carrying harness. This means that all of the weight of the
apparatus can now be placed comfortably and securely where it should
be - on the hips - in line with the bodyís centre of gravity.
Utilising hard wearing materials, improved padding, new adjustment
technology, and combining Dragerís famous pull forward waist
adjustment, the PSS 90 ensures that donning and wearing of professional
Breathing Apparatus has never been so simple or trouble free.
Improved Wearer Comfort
The PSS 90 features an orthopaedically designed backplate
moulded from glass-filled polyamide with carbon fibre for
resilience and strength. Following the natural contours of the
back and attached securely to the fully padded waistbelt
assembly, the result is a carrying system which ensures that
the weight of the apparatus and cylinders is concentrated on
the hips - thereby reducing backstrain, stress and fatigue.
Designed to endure the harsh environments within which
todayís fire and rescue professionals are expected to
perform, every component is manufactured to a high degree
of chemical, heat and flame resistance. PSS 90 is fully
designed and tested to comply with the highest flame
engulfment standards in the world, including NFPA 1981:1997
and PrEN 137. The anti-static composite backplate,
incorporating moulded carrying handles, is flexible and impact
resistant without compromising wearing comfort.
The materials used throughout have been carefully chosen to
provide the greatest possible chemical and wear resistance,
including a high proportion of Kevlar, Nomex and other
The PSS 90 will accommodate all common cylinder
configurations from a single 4.0 Litre steel to Dragerís own
manufactured twin 9.0 Litre carbon fully wrapped cylinders,
with only a minor adjustment to the Nomex cylinder band
which incorporates a cam lock design locking mechanism.
The PSS 90 can also be modified to accept Dragerís
dedicated Twinpack arrangement.
Dragerís PSS family is founded on a modular approach,
which means that a range of options is available to provide
the perfect solution to any application.
Utilises the proven ĎPlusí pneumatic system, requiring
minimum maintenance year on year and featuring Dragerís
unique medium pressure driven whistle warning unit, which is
integrated into the fully luminescent pressure gauge for snag
resistant streamlined handling. Other features include built in
compatibility with electronic monitoring options, ChargAir port
for quick filling and our patented safety pressure relief valve.
Lung Demand Valve
The Plus Lung Demand Valve carries on Dragerís tradition
of balanced piston designs offering stability, quiet operation
and, of course, is first breath activated. A centrally located switch
off button and tough wrap around silicone cover are incorporated
in a modern streamlined shape for easy handling-even when
The PSS 90 is Dragerís flexible professional choice
which allows the final configuration of pressure and safety
monitoring to be a matter of customer choice according to
budget. Regardless of the level at which you start there is a cost
effective upgrade available for higher sophistication.
