Ahlstrom has introduced innovative fluoro-free technologies for industrial air filtration applications, aimed at supporting filter manufacturers in creating high-performance products without the use of fluorochemicals. These new materials are ideal for a variety of applications such as gas turbine air intake, air pollution control, and HVAC systems. The water-repellent properties of these materials increase the durability and stability of the final filter, especially in wet conditions, making them essential for maintaining filtration performance in challenging environments.
In air pollution control applications, hydrophobic materials help save energy by limiting pressure drop increases in humid conditions. In gas turbine applications, water repellency plays a crucial role in preventing liquid water and dissolved salt from penetrating the filter and causing corrosion to the turbine. Ahlstrom’s fluoro-free solutions are designed with safety and sustainability in mind, offering customers alternative options that meet their performance requirements and contribute to a cleaner, safer, and more sustainable future for filtration.
The new fluoro-free filtration materials are available globally and can be accessed through Ahlstrom’s Trinitex®, CellTech, and Glass production platforms. With this innovative range of materials, Ahlstrom is paving the way for a shift away from fluorochemistries in industrial air filtration, providing customers with effective and eco-friendly solutions for their filtration needs.
