SLS rebreathers
SLS Mark IV
The Secondary Life Support (SLS) System is an emergency breathing apparatus intended for use by professional saturation divers, operating from a diving bell. The system is intended for use in the event of a fundamental failure of a diver’s primary life support system.
The System operates on a semi-closed circuit principle with complete independence from the diver’s primary breathing system.
The SLS provides a greater endurance that a standard twin bail-out set which is more commonly used in the industry.
| Depth | SLS | Bail-out |
|---|---|---|
| 50msw | 30 mins | 17.5 mins |
| 100msw | 30 mins | 9.5 mins |
| 150msw | 28 mins | 6.6 mins |
| 200msw | 22 mins | 5 mins |
| 250msw | 19.5 mins | 4.0 mins |
| 300msw | 17.5 mins | 3.4 mins |
