Introducing the GIS4: The Next Generation of Gas Inflation Systems
Today marks a significant milestone in maritime safety innovation as we proudly launch the GIS4, our latest Gas Inflation System that represents over three decades of expertise and engineering excellence.
Building on a Legacy of Trust
Since 1992, our original GIS has been the gold standard in gas inflation systems, with over 250,000 units manufactured and trusted by the world’s leading life raft manufacturers for SOLAS life-rafts. The GIS4 embodies the DNA of our world-leading product range, utilising the same tried, tested, and trusted principles that have made our systems the choice of industry leaders for more than 30 years.
The GIS4 Advantage: Smaller, Lighter, Smarter
The patented GIS4 represents a significant evolution in gas inflation technology, offering substantial improvements over both our GIS and GIST systems:
Size and Weight Optimisation
One of the most notable advantages of the GIS4 is it’s reduced footprint. The system is both smaller and lighter than previous GIS and GIST operating head systems, making it easier to integrate into life rafts and marine evacuation systems without compromising on performance.
Simplified Maintenance
The GIS4 features minimised spares requirements with cross compatibility to GIS(T), reducing the complexity and cost of maintenance operations. This streamlined approach means easier to manage inventory and faster serviceability.
Enhanced Versatility
Available in both plated and non-plated, single and dual port versions as well as with looped and non-looped cable options, the GIS4 offers flexibility to meet diverse application requirements. This adaptability ensures the system can be tailored to specific operational needs across different vessel types and safety equipment configurations.
Uncompromising Performance and Safety
Despite its reduced size, the GIS4 maintains the exceptional performance characteristics that Leafield Marine systems are renowned for:
- Fast, consistent inflation times even on the largest life rafts
- Guaranteed Full activation regardless of painter/lanyard pull speed
- Extreme reliability and ruggedness in the harshest marine environments
- Versatile gas compatibility with CO2, CO2/Nitrogen, air, and Nitrogen
- High-pressure capability with versions available for cylinders up to 300 bar test pressure
Comprehensive Certification
The GIS4 meets and exceeds the most stringent international safety standards:
- ISO 15738 approved for SOLAS use on life-rafts
- ISO 9650-1:2022 (Small Craft Inflatable Life Rafts Type 1 and Type 2)
- Approved to European Pressure Equipment Directive 2014/68/EU
Ideal Applications
The GIS4 system delivers Leafield Marine’s renowned reliability for wide range of critical safety applications:
- SOLAS life-rafts
- Marine Evacuation Systems (MES)
- RIB self-righting bags
Its compact design makes it particularly ideal for complex leisure and sports applications where space and weight are at a premium, yet performance cannot be compromised.
Choosing the Right System
While the GIS4 represents our most advanced offering with significant size and weight advantages, we continue to manufacture our complete range of gas inflation systems to meet diverse industry needs:
- GIS4: Our latest system offering optimal size and weight savings with full functionality
- GIS: The original system, ideal for complex MES and multi-cylinder applications requiring specific Nitrogen, high-pressure up to 400 bar, high-volume applications
- GIST: Our compact torsional system, widely used in commercial life-raft applications.
Expert Support Every Step of the Way
