Finland's Ahlstrom unveils new sustainable PFAS-free filtration media

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 multi-layer air-oil separation solutions in collaboration with the customers, the company said in a press release.       

“Our new PFAS-free solution underscores our commitment to innovating sustainable solutions, supporting the transition to environmentally responsible alternatives without compromising performance,” said Tamara Quatrano, vice president, R&D and product development, filtration. “We are actively collaborating with our customers' R&D teams to further develop and optimise PFAS-free filtration media.”

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