The Dräger PSS 4000 is a lightweight, robust and professional self-contained breathing apparatus (SCBA) designed specifically for firefighting and other demanding applications where reliable respiratory protection, mobility and ease of use are essential. Combining advanced pneumatic technology with an ergonomic carrying system, the PSS 4000 delivers dependable breathing protection while helping to reduce physical strain during extended periods of use.
At just 3 kg for the backplate and harness, the PSS 4000 is designed to minimise the weight carried by the wearer. Its high-strength composite carrying frame provides excellent resistance to heat, impact and chemicals, while the ergonomic design follows the natural contours of the body. This helps improve stability and distribute the load comfortably around the shoulders and waist, reducing back strain, stress and fatigue.
The harness uses durable, high-performance materials designed to withstand the demanding conditions encountered by professional firefighters. Stainless-steel buckles and long-life aramid-fibre webbing provide a combination of durability and comfort, making the system suitable for frequent use and extended wear.
Ease of use is another key feature of the PSS 4000. The carrying harness incorporates a quick-release fastener and a simple forward-pull adjustment mechanism, allowing the wearer to quickly achieve a secure and comfortable fit. The closed, single-piece harness and waist-pad design also limits water absorption, helping to reduce cleaning and drying times.
The PSS 4000 incorporates integrated medium-pressure air supply and gauge hoses within the carrying frame. This reduces the risk of snagging and entanglement, which is particularly beneficial when working in confined or difficult-to-access areas. The hoses can also be routed from one side of the apparatus to the other, providing flexibility in gauge positioning and making hose replacement easier.
The apparatus uses the proven pneumatic technology found in Dräger’s professional PSS range and can be configured to suit different operational requirements. It supports both single- and two-cylinder configurations and can be equipped with Dräger FPS 7000 or Panorama Nova full-face masks. Additional options include electronic voice communication, rescue and decontamination hoses, rapid charging, and a charge-air connection.
For enhanced monitoring and firefighter safety, the PSS 4000 can be configured with systems such as the Dräger Bodyguard 1500 wireless PASS. Depending on the configuration, the system can provide wireless pressure data transmission, automatic personal alert functions and compatibility with the FPS 7000 Head-Up Display (HUD).
With a maximum input pressure of up to 300 bar and approvals including EN 137:2006 Type 2, EN 14593 Part 1, SOLAS II-2 and MED, the Dräger PSS 4000 is a versatile SCBA solution for professional firefighting, marine applications and other environments where dependable respiratory protection is critical.
Overall, the PSS 4000 combines low weight, robust construction, ergonomic carrying characteristics and configurable technology in a platform designed for firefighters who need reliable performance without unnecessary complexity.
