SEA 4500-Survival Egress Air

SEA stands for Survival Egress Air. Designed for helicopter aircrews operating over water, this device provides precious minutes of breathing air in the event of emergency ditching at sea.


Designed for helicopter aircrews for use in the event of emergency ditching in aquatic or marine environments, the Aqua Lung SEA-4500 offers next generation egress device technology. Engineered for the toughest environments, it is the best performing  system on the market. Improved breathing performance means easier breathing under demanding conditions. The carbon fiber composite cylinder and newly engineered design reduces the weight by 40%.

Most importantly, the SEA-4500 operates at a higher pressure with increased capacity, which delivers 33% more air. Greater air volume significantly increases your survivability in virtually every emergency situation.
