Reducing Environmental Impact Without Compromising Fuel Quality or Safety
As the aviation industry works towards ambitious sustainability targets, every part of the fuel supply chain is being challenged to deliver greater efficiency, lower emissions and reduced waste.
Filtration technologies play a critical role in ensuring fuel quality and operational safety. Today, they must also contribute to environmental performance. Modern filtration solutions can help reduce carbon emissions, extend service life, minimise hazardous waste and support operators in achieving their sustainability objectives.
At sefiso | FAUDI Aviation, sustainability is not an afterthought. It is engineered into every stage of our product development, from material selection and manufacturing processes to operational performance and lifecycle management.

The aviation industry is facing a period of significant transformation.
Why Sustainability Matters in Aviation Fuel Filtration
The aviation industry is facing a period of significant transformation.
Growing adoption of Sustainable Aviation Fuels (SAF), increased fuel imports, evolving industry specifications, and global commitments to reduce carbon emissions are reshaping fuel handling operations worldwide. At the same time, operators are expected to maintain the highest standards of fuel cleanliness and safety.
Filtration technologies must therefore deliver more than compliance. They must actively contribute to sustainability by:
- Reducing resource consumption
- Extending filter operating life
- Lowering hazardous waste generation
- Improving operational efficiency
- Supporting carbon reduction initiatives
Recent industry specifications, including the latest editions of EI standards, now place increasing emphasis on sustainability considerations when developing aviation fuel filtration technologies
A New Generation of Sustainable Filtration Technology
Traditional coalescer designs have remained largely unchanged for decades.
The latest generation of S-Type Coalescer and T-Type Coalescer technologies has been developed to address both operational and environmental challenges facing modern aviation fuel systems.
By rethinking materials, construction methods and lifecycle performance, these technologies deliver measurable sustainability benefits throughout their operational life. Key benefits include:
| Criteria | P-Type | T-Type | S-Type |
|---|---|---|---|
| Typical application | Where similarity data requires | Mobile / into-plane applications | Stationary, fixed applications |
| Coalescing media & design | Conventional materials (e.g. glass fibre) | New coalescing media, automated manufacturing | New coalescing media, automated manufacturing |
| Sustainability & CO₂ footprint | Higher CO₂ emissions due to glass fibre, not optimizsed for carbon efficiency | Significantly lower CO₂ emissions, demonstrate a measurable reduction in carbon footprint | Significantly lower CO₂ emissions, demonstrate a measurable reduction in carbon footprint |
| Drain-down time | Slower drain-down time compared to T-Type & S-Type | Faster drain-down time compared to P-Type | Faster drain-down time compared to P-Type |
Sustainable Solutions for Every Application

AFGUARD® Electronic Water Sensor
Extending Sustainability Beyond Filtration
True sustainability means combining better filter design with the longest possible service life of filtration systems.
AFGUARD® continuously monitors free water concentration in aviation fuel, providing real-time verification of filtration performance. This enables operators to move beyond traditional time-based replacement schedules towards a more intelligent, condition-based approach.
The result is:
- Longer filter life
- Reduced waste generation
- Lower operating costs
- Improved asset utilisation
- Enhanced fuel quality assurance
By supporting PerformanceBasedFilterLife™, AFGUARD® helps operators achieve both environmental and operational objectives simultaneously
