Ahlstrom lead

Ahlstrom-Munksjö is a world-leading supplier of fiber-based materials and filter media, providing ground-breaking and ecological solutions for both static and pulse-jet gas turbine air intake applications.

The company manufactures products for a variety of customers and supports the need for a clean and healthy environment with its range of globally available power generation solutions.

Expert fiber and filter media technology for power applications

Ahlstrom-Munksjo's expertise and latest know-how in various nonwoven technologies and chemistries provides filter manufacturers several advanced solutions in many technical platforms.

The media technology, fiber composition, and resin chemistries are carefully chosen according to the specific filter performance requirements. The company's filter media can be used in:

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

Ahlstrom-Munksjö Trinitex® for efficient filtration solutions

Due to its unique three-layer structure, Trinitex® technology is a filter media with excellent mechanical separation efficiency and low-pressure drop.

Ahlstrom-Munksjö is able to customise each layer in order to provide customers with an overall product that suits their equipment. This allows an optimal combination of strength and mechanical particle removal efficiency at small particle sizes and pressure drop.

Trinitex® is easy to process on rotary and knife pleating lines.

Microglass technology for air intake filtration

Ahlstrom-Munksjö offers Microglass technology that guarantees consistent efficiency in the final stage of air intake filtration, ultimately protecting the turbine.

Microglass filter media is available in dual layer design, which provides the product with increased dust-holding capacity while maintaining the highest possible efficiency.

This type of media is the finest solution for F7-F9 static filters and HEPA filter applications.

SafePulse for reverse-pulse applications

Corrugated filter media for reverse-pulse facilities covers material compositions from 100% cellulose to 100% synthetic solutions. The media has efficiency levels from M5 to F9 according to EN779-2002 and EN779-2012.

Ahlstrom-Munksjö's SafePulse filter media has various physical properties that can be tailored to customer's individual needs and designed for different process conditions and requirements.

The company's proprietary resin chemistry provides high strength, superior water resistance to guarantee performance in humid conditions, and optional features such as fire retardancy.
XAir filter media and high dust holding capabilities

Ahlstrom-Munksjö's XAir filter media merges the benefits of the SafePulse media and fine fiber meltblown technology to ensure high-quality reverse-pulsing techniques, as well as high dust-holding capabilities for prolonged pulse cycles.

NanoPulse™ for efficient mechanical processing

NanoPulse™ consists of SafePulse media coated with electrospun nanofibers on the upstream side to enable first-class reverse-pulsing performances and high mechanical efficiency at the lowest achievable pressure drop.

The product can also be customised with beneficial treatments such as those ensuring fire-resistancy.
