Now obsolete. The replacement is the Airboss. The model choice will depend on your application. For Full firefighting and casualty rescue, an Airboss Connect is required; for standard industrial use, select the Airboss Active.
Drager has led the design of advanced respiratory protection equipment for more than a century. Through continuous product improvement and investment in technology, we have developed a range of products that advance compressed-air breathing equipment and enhance personal safety.
PSS 90 is the newest addition to Drager’s family of Personal Safety Systems. Fitted with Drager’s high-performance advanced ‘Plus’ 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 body’s centre of gravity.
Utilising hard-wearing materials, improved padding, new adjustment technology, and combining Drager’s famous pull-forward waist adjustment, the PSS 90 ensures that donning and wearing of professional Breathing Apparatus has never been so trouble-free or straightforward.
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 securely attached to the fully padded waistbelt assembly, the result is a carrying system that distributes the weight of the apparatus and cylinders to the hips, reducing back strain, stress, and fatigue.
Rugged Design
Designed to endure the harsh environments in which today’s fire and rescue professionals are expected to perform, every component is manufactured with high chemical, heat, and flame resistance. PSS 90 is fully designed and tested to comply with the highest flame-engulfment standards worldwide, 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 aramid materials.
Adaptable
The PSS 90 will accommodate all common cylinder configurations, from a single 4.0 Litre steel cylinder to Drager’s 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 locking mechanism. The PSS 90 can also be modified to accept Drager’s dedicated Twinpack arrangement.
Drager’s PSS family is built on a modular approach, offering a range of options to provide the perfect solution for any application.
Reliable
Utilises the proven ‘Plus’ pneumatic system, requiring minimum maintenance year on year and featuring Drager’s 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, a ChargAir port for quick filling, and our patented safety pressure relief valve.
Lung Demand Valve
The Plus Lung Demand Valve continues Drager’s tradition of balanced piston designs, offering stability, quiet operation, and, of course, first-breath activation. A centrally located switch-off button and tough wrap-around silicone cover are incorporated in a modern, streamlined shape for easy handling, even when wearing gloves.
Flexibility
The PSS 90 is Drager’s flexible professional choice, allowing the final configuration of pressure and safety monitoring to be tailored to the customer’s budget. Regardless of your starting level, a cost-effective upgrade is available to increase sophistication.
