Product Description
This is the original system developed by Leafield Marine and was introduced in 1992. It is well proven with over 250,000 manufactured and is used by some of the world’s leading life raft manufacturers on their SOLAS life-rafts. Typical uses include SOLAS life-rafts, Marine Evacuation Systems, RIB self-righting bags and buoyancy bag inflation.
This system is ideal for use with complex Marine Evacuation Systems and other multi cylinder applications. Versions are also available with a pressure gauge/water activation/electrical activation/servo system.
The GIS system uses a patented cutter system to ensure consistent, rapid inflation times, even on the largest life rafts.
Due to the safety critical nature of this product and number of variants available, we suggest that you contact Leafield Marine directly to discuss your specific needs.
Please see Gas Inlet Valves and Hoses for use with this GIS system.
For single cylinder inflation systems, please see our compact Gas Inflation System Torsional (GIST type).

Accessories and Service Tools
Nitrogen valve with gauge
This variant provides accurate indication of cylinder pressure and can be supplied with internal or external over pressure venting.
High energy operating head
Designed for use on systems fitted to cylinders of 300 bar and above.
Gas Inflation Servo System
This unit replaces the standard operating head and combined with a servo adaptor and Hoses allows up to four cylinders to be fired from one manual Operating Head.
Water activated Gas Inflation System
This unit can be used to fire a Servo System when immersed in water. This is particularly useful on items such as self-righting bags and built-in buoyancy systems.
Electrically Operated Gas Inflation System
This unit can be used to fire the Inflation System using an electrical signal.
