To address this growing demand, Ahlstrom, a global leader in innovative filtration solutions, is proud to introduce a groundbreaking PFAS-free filtration platform with water-repellent properties specifically designed for air-oil separation applications. This new solution offers filter manufacturers a sustainable alternative to meet stringent regulatory and performance demands while maintaining durability and reliability.

The air-oil separation market requires high-performance materials capable of efficiently separating fine oil and water aerosols from air streams while maintaining excellent filtration performances. In multilayer filter structures, media treated with water-repellent properties enhances the coalescing effect. This ensures the media remains stable, avoiding increased wet pressure drops and preserving filtration efficiency. Traditionally, these challenges were addressed using PFAS-based technologies. Ahlstrom’s PFAS-free filtration materials eliminate the need for fluorochemicals, delivering advanced water-repellent properties that ensure reliable and robust performance, even in demanding operating conditions. A dedicated test bench supports the development and qualification of our multi-layer air-oil separation solutions in collaboration with our customers.       

“Our new PFAS-free solution underscores our commitment to innovating sustainable solutions, supporting the transition to environmentally responsible alternatives without compromising performance,” says Tamara Quatrano, Vice President, R&D and Product Development, Filtration. “We are actively collaborating with our customers’ R&D teams to further develop and optimize PFAS-free filtration media.”

The PFAS-free filtration media is now available through Ahlstrom’s glass microfiber production platform in Fabriano, Italy, and is designed for use in industrial applications and sectors.
