Brand new Dräger Ray Semi-Closed Rebreather

The Dräger Ray Rebreather: A Dive into Innovation

When it comes to the world of recreational diving, few names command as much respect as Dräger. Founded in 1889 in Lübeck, Germany, the company built its reputation on cutting-edge breathing and protection equipment, with a history steeped in innovation. In 1999, Dräger revolutionized recreational diving with the release of the Dräger Ray, a semi-closed circuit rebreather designed for underwater explorers.

Why Did Dräger Create the Ray?

By the late 20th century, rebreathers had become essential tools for military and professional divers. These devices provided extended dive times, reduced gas consumption, and minimized bubble trails. However, their complexity, bulk, and cost often kept them out of reach for recreational divers. Dräger recognized this gap and sought to make rebreather technology accessible to a broader audience. The Dräger Ray was their answer—a sleek, user-friendly option that brought the advantages of advanced diving within reach.

Dräger aimed to offer recreational divers the benefits of rebreather technology—such as longer bottom times and silent operation—while keeping the system simple, safe, and adaptable to standard nitrox gas mixes.

A Closer Look at the Dräger Ray

Dräger engineered the Ray with the recreational diver in mind. Here’s what set it apart:

  • Harness and Counterlungs: The Ray includes a soft harness with integrated over-the-shoulder counterlungs and a built-in buoyancy compensator. This design prioritizes comfort, allowing divers to carry the unit easily and maintain buoyancy control.
  • Breathing Loop: The unit features a simple dive-surface valve (DSV) with a mouthpiece. Divers could upgrade it to connect with the Dräger Panorama full-face mask, offering flexibility for those seeking a more comprehensive experience.
  • Gas Supply and Versatility: The semi-closed circuit system delivered a consistent flow of gas. It worked seamlessly with standard nitrox mixtures like EAN 32, EAN 40, and EAN 50, and even allowed for 100% oxygen with additional modifications. This adaptability made it a favorite among divers who wanted to push boundaries.
  • Compact Design: Dräger placed the scrubber canister and single transversely mounted cylinder strategically for balance and maneuverability. Weighing just 15 kilograms, the unit was remarkably portable for its time.

Diving Performance

The Dräger Ray offered impressive performance for recreational diving. With different gas mixtures, divers could reach depths of up to 40 meters (using EAN 32) and enjoy dive durations of about 70 minutes on EAN 50. These capabilities made it a popular choice among photographers, naturalists, and anyone eager to spend more time exploring the underwater world.

Dräger’s Legacy in Diving

Dräger’s journey into the underwater world began long before the Ray. The company had already spent decades producing rebreathers for military divers, rescue operations, and scientific exploration. Their expertise in gas management, safety, and system design laid the groundwork for the Ray’s robust reputation. By leveraging this experience, Dräger successfully introduced a recreational rebreather that combined reliability with user-friendliness.

Why Divers Love the Dräger Ray

Enthusiasts, particularly in Europe, continue to celebrate the Dräger Ray for its compact design and reliable performance. Facebook groups and diving forums buzz with discussions about customizing the Ray, sharing diving experiences, and reflecting on its place in diving history.

One popular modification involves custom counterlungs, which allow divers to further optimize the unit for specific needs. These ongoing conversations highlight the Ray’s enduring legacy as a tool that inspires creativity and exploration.

A Modern Dive into History

Although Dräger no longer manufactures the Ray, the diving community still cherishes its influence. It represents Dräger’s commitment to innovation and marks a significant moment when rebreathers became accessible to recreational divers.

For anyone lucky enough to own a Dräger Ray today, it’s more than just a piece of equipment—it’s a piece of diving history. Whether you’re a seasoned rebreather enthusiast or a collector of vintage diving gear, the Ray provides a fascinating glimpse into the evolution of underwater technology.

So, next time you’re scrolling through diving forums or swapping stories with fellow divers, celebrate the Dräger Ray—a rebreather that redefined recreational diving and opened the door to silent underwater exploration.
