Filter Media Solutions and Technologies

Ahlstrom lead

Ahlstrom is a high performance fiber-based materials company, partnering with leading businesses around the world to help them stay ahead.

It aims to grow with a product offering for a clean and healthy environment. Ahlstrom manufactures filter media solutions and fiber based materials for a range of industries and applications.

Ahlstrom's solutions for power generation, which are available globally, are based on several technical platforms. Our expertise and latest knowhow in various nonwoven technologies and chemistries is applied to provide several advanced solutions to filter manufacturers.

The media technology utilised and the selection of the fiber composition and resin chemistries are carefully chosen according to the specific filter performance requirements. Our filter media can be used in:

  • Pleated filters for pre-filtration
  • Pleated bank and cartridge filters for primary filtration
  • Pleated filters for HEPA filtration

Ahlstrom Trinitex® GT

Ahlstrom Trinitex® GT technology offers filter media with excellent mechanical filtration efficiency and low-pressure drop thanks to its unique 3-layer structure.

Each layer can be customised to deliver specific properties and the optimal combination of strength, mechanical particle removal efficiency even at small particle sizes, and pressure drop. Ahlstrom Trinitex® GT is easy to process on rotary and knife pleating lines.

Ahlstrom Microglass GT filter media

Our Microglass technology guarantees consistent efficiency in the final stage of air intake filtration, which ultimately protects the turbine.

Ahlstrom Microglass GT media is available in dual layer design, which provides the media with increased dust holding capacity while maintaining the highest possible efficiency. Our Microglass Gt media is the best media for static filters F7-F9 and HEPA filter applications.

Ahlstrom SafePulse™

Our portfolio of corrugated media for reverse-pulse applications covers material compositions from 100% cellulose over the famous 80 / 20 media to 100% synthetic solutions, and efficiency levels from M5 to F9 according to EN779-2002 and EN779-2012.

We offer media with various physical properties tailored to our customers individual needs and designed for different process conditions and requirements. Our proprietary resin chemistry provides high strength, superior water resistance to guarantee performance in humid conditions, and optional value adds such as fire retardancy.

Ahlstrom XAir GT

Ahlstrom's XAir GT media combines the advantages of our SafePulse™ media and our Fine Fiber Meltblown technology to deliver a media with excellent reverse-pulsing properties as well as high dust holding properties for extended pulse cycles.

Ahlstrom NanoPulse™

Ahlstrom NanoPulse™ consists of our SafePulse™ media coated with electrospun nanofibers on the upstream side.
This structure results in excellent reverse-pulsing behavior and high mechanical efficiency at the lowest possible pressure drop.

Like our SafePulse™ family, NanoPulse™ can also be customised with value-added treatments such as fire retardancy.

Full range of technologies and benefits, Ahlstrom is a single source provider of filter media solutions for both static and pulse-jet gas turbine air intake applications.
