DIVEX Logo COBRA (Compact Bailout Rebreathing Apparatus)

INTRODUCTION

COBRA is a back-mounted emergency breathing system which provides life support in the event of primary breathing system failure. It is a semi closed circuit design which provides far greater duration than that of the open-circuit bail-out systems.

COBRA provides significant safety advantages to commercial saturation diving activities:

Offline Positive pressure

Maintains breathing lop integruty during rapid ascent. A Rotowink positive pressure indicator provides visual assurance of breathing lopp integrity.

Warmth & Hydration

Rebreathed gas is warm and humid. maintaining divers' core temperature and reducing dehydration.

Simple activation

COBRA is activated, and de-activated, with a single turn on the helmet.

Fully Enclosed

Protection of the breathing circuit is maximised by COBRA's fully enclosed design/

Optimum Scrubbing Duration

COBRA's pre-heated CO2 scrubbing system maximises CO2 absorption duration.

Rapid Recharge

Scrubber and gas supply are quickly recharged, ready for their next deployment.
