Insights

Ahlstrom has unveiled a groundbreaking dual-layer filter media technology globally, revolutionizing filtration efficiency.
With double the dust holding capacity compared to single-layer designs, it optimises particle retention.
Tested in automotive engine air intake, it extends filter lifetime by 50 per cent, while reducing size and weight.

Ahlstrom has introduced a new dual-layer filter media technology, available globally, that represents a leap forward in filtration and is a perfect solution to comply with future market needs. The dual-layer design offers up to double dust holding capacity compared to the single-layer design, as each layer serves a distinct purpose to optimise the overall retention of particles in the depth of the material.

In automotive engine air intake applications, the technology has proven to extend by over 50 per cent the filter lifetime in the same configuration. It also offers the possibility to reduce both size and weight of the filter element in vehicles where these parameters are important, the company said in a press release.

Dual-layer filter materials are designed to comply with current and future engine air intake specifications, including fuel cells. The media can be customised with flame retardancy properties to increase safety in use without compromising performance. The technology is highly adaptable and can be extended to filter air and liquid in many other transportation and industrial applications.

“Leveraging our advanced manufacturing processes and know-how, Ahlstrom’s dual-layer filter media are setting new standards for filtration performance on the market,” said Tamara Quatrano, VP of R&D and product development for the filtration division. “They can be adapted to different environments, and they not only purify and protect but also contribute to a more sustainable future.”
