About Dräger

Since 1889, following the first pressure reducer valve patented by Dräger and Gerling; Dräger has established itself as the world leader and innovator of quality diving equipment for many and varied applications for the military, the professional diver and of course the recreational diver as well.

Since then many years of research and development have been spent producing ground breaking equipment such as hose free helmet diving in 1912, the oxygen closed circuit diving apparatus as early as 1926, the mixed gas closed circuit set for exciting deep diving bells in 1969, this led to the release of the military version for mine clearance diving.

Through the years Dräger has continued to further develop and supply the world's diving companies and military forces with cutting edge rebreather diving technology; this expertise is now available to you in the form of the Dolphin and DrägerRay semi-closed rebreathers.

You dive into the water and from one second to the other you are in a different world. Stress, noise and the hustle and bustle of everyday life suddenly seem to be far away. You become one with the silent world and are actually aware of your senses. No noisy valves, no hissing air, no annoying air bubbles - nothing!

Dräger Dolphin - proven technology for the sophisticated rebreather diver.

The Dräger Dolphin rebreather stands out because of its robust and reliable technology. It offers you a great variety of accessories enabling you to individually extend your fields of application.

Its perfected technology is protected by a sturdy shell, the buoyancy jacket is equipped with an integrated weight drop system. Optionally an oxygen monitoring device may be integrated in the brea- thing circuit.

The "Oxygauge" constantly indicates the oxygen partial pressure in your breathing circuit. Five different dosage devices enable you to dive the Dolphin with four Nitrox mixtures and pure oxygen.

As a result the advantages of pre-mixed Nitrox are extended:

• Improved re-use of breathing gas
• Bubble-free and noise-free diving
• Warm and moist breathing gas
• Sturdy and safe technology

The Oxygauge constantly displays the oxygen partial pressure in your breathing circuit.
