Product Description

The Patented GIS4 is the latest Gas Inflation System developed by Leafield Marine building on our heritage of over 30 years of expertise and experience manufacturing Gas Inflation products . The DNA of our world leading product range is embedded within GIS4 utilising the same tried, tested and trusted principles of the original GIS that was first manufactured in 1992 and is used by some of the world’s leading life raft manufacturers on their SOLAS life-rafts. The GIS4 system is suited for use in SOLAS life-rafts, Marine Evacuation Systems, RIB self-righting bags and buoyancy bag inflation offering size and weight savings over our GIS and GIST operating head systems.

The GIS4 system is ideal for use with complex Marine Evacuation Systems and other multi cylinder applications providing 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 GIS4 system.
