Ahlstrom is leading the marketplace towards more sustainable, fluoro-free solutions for fiber-based solutions. Today, Ahlstrom extends its innovative fluoro-free technologies into a wide range of industrial air filtration applications to support filter manufacturers in creating products with long-lasting filtration performance without the use of fluorochemicals.

Ahlstrom's new fluoro-free filtration materials are ideal for gas turbine air intake, air pollution control, heating, ventilation, and air conditioning (HVAC) applications. The new range of materials offers water-repellent properties, which increase the durability and stability of the final filter in wet conditions. In global filtration markets, hydrophobic properties are essential to maintaining the highest filtration performance in challenging environments.

In air pollution control applications, for example, hydrophobic materials save energy by limiting the pressure drop increase in humid conditions. Specifically, in gas turbine applications, water repellency prevents liquid water ingress and dissolved salt penetration through a filter, protecting the turbine from corrosion.
