Preventing contamination of jet fuel enhances engine reliability and ensures high flow-through rates during flight operations to improve fuel efficiency.

Our monofilament fabrics for coalescers efficiently remove water and particles from fuel. With precise mesh openings, hydrophobic coatings, maximized seam strength, and high flow-through rates, our filtration solutions help maintain fuel quality, reduce maintenance, and support safe, uninterrupted engine performance.
