The Drager PSS 4000 SCBA is light, easy to use, and contains advanced ergonomics with a wide range of configurable options. Supported by a carrying harness with a quick-release fastener and simple pull forward mechanism, you can quickly adjust the carrying harness, providing comfort and versatility to meet first responders’ demands whenever breathing protection is required.

Using established PSS pneumatics and cylinder strap design, the PSS 4000 combines proven technology, state-of-the-art materials and innovative thinking to create an SCBA for most applications. Designed to withstand the high wear and tear that firefighters face daily, featuring hard-wearing stainless steel buckles and long-life blend webbing made from aramid fibre.

Enhanced carrying system

The highly durable carrying system features our ultra-lightweight, high strength composite carrying space frame, which provides outstanding thermal, impact and chemical resistance properties. The harness’s professional carrying system follows the body’s natural contours, improving stability and reducing back strain, stress, and fatigue. The system offers optimal comfort for the wearer’s shoulders and waist with even load distribution, comfortably and securely in line with the body‘s centre of gravity. Aside from maximum comfort, the PSS 4000 also uses the most rugged and durable materials available to minimise the impact of even the most hostile environments.

Easy to maintain and service

Aside from being quick and easy to service, the SCBA comes with various innovative design features that reduce downtime and unnecessary maintenance costs. This can be seen in all major components, which are quick and straightforward to remove and re-assemble. The harness is attached to the carrying frame by an innovative single-piece retention method. For added convenience, the first stage pressure reducer is integrated into the carrying frame. The closed, single-piece harness and waist pad design prevents excessive water absorption, which reduces cleaning and drying time whilst optimising energy efficiencies.

Integrated hoses

The medium pressure air supply and gauge hoses are entirely integrated into the carrying-frame to reduce snagging and potential entanglement risk. This substantially improves security and safety while entering and working in confined spaces. An additional benefit is the ability to re-route the hoses from one side to the other to suit customer preferences for gauge access. This design feature also facilitates the easy replacement of each hose.

Wireless option

Enhance your safety in the field with the Drager Bodyguard 1500, an advanced personal alert safety system (PASS). This breathing protection control and non-motion-detector generate visual and acoustic alert signals if you are motionless, running out of air or exposed to extreme heat. Furthermore, the system provides wireless data transmission between the PASS and the monitoring devices.

The backlit Tx Gauge wirelessly transmits its pressure data to the Bodyguard 1500 and also to the FPS 7000 Head-Up-Display (HUD) if being used. This feature provides automatic visual notification from the Tx Gauge and acoustic notification from the PASS when the air supply drops below user-defined limits.

Additional options

The flexible, user-friendly, high-performance system combines both new and proven innovative technology. The PSS 4000 guarantees a lifetime of dependable service, simultaneously minimising the costs of ownership while offering a broad choice of options for every eventuality:

  • Choice of lung demand valves
  • FPS 7000 full facemask configuration options (as well as Panorama Nova)
  • Electronic voice communications
  • Steel or carbon composite cylinders
  • Secondary supply hose connections for rescue and decontamination
  • Bodyguard 1500 for wireless transmission of pressure data
  • FPS 7000 Head-up-Display (HUD) and Tx Gauge with entry-level electronics
  • Rapid charge option
  • Twin-cylinder configuration

Proven air supply technology

Versatility is one of the main principles of the Drager PSS product series. This is why PSS 4000 enables you to benefit from the other models’ technological progress. Incorporating the same advanced pneumatic system used in the class-leading PSS 7000, the PSS 4000 offers you professional equipment for pioneering fire departments. Also, the twin-cylinder option enables you to increase the air supply and benefit from a longer duration.
