We are official dealers for Griffin filters for fuel and water separators.
The water is being filtered in 4 phases:
1. CENTRIFUGAL STAGE - Larger solid contaminants and free water are separated.
2. COALESCING STAGE - Smaller water droplets and solid contaminants are filtered out by multigrade filtration media, causing them to coalesce together and fall into the collection bowl.
3. MICRO ACTION I STAGE - Micro action filtration removes the smallest water droplets and solid contaminants from fuel.
4. MICRO ACTION II STAGE - A second micro action filtration ensures nearly 100% pure fuel filtration.
