Gas Turbine filter media

Ahlstrom-Munksjö is a single-source provider of filter media solutions for both static and pulse jet gas turbine air intake applications.

Ahlstrom-Munksjö’s solutions for gas turbine air intake filtration are based on several technical platforms. Our expertise and experience in various nonwoven technologies and chemistries has enabled us to provide various advanced solutions for filter manufacturers. Media technologies, and selection of fiber composition and resin chemistries, are carefully chosen according to specific filter performance requirements.


  • A complete range of media from 100% cellulose to 100% synthetic or microglass in various combinations for all stages of power generation air intake filtration
  • Filter media designed to offer solutions for a variety of operational environments and temperatures: high humidity, sand, salt, soot, dust, fog, snow etc.
  • Ability to customize products according to customer-specific performance requirements

Ahlstrom-Munksjö Trinitex®

Trinitex® technology offers filter media with excellent mechanical filtration efficiency and low pressure drop thanks to its unique 3-layer structure. Each layer can be customized to deliver specific properties and an optimal combination of strength, mechanical particle removal efficiency (even at small particle sizes), and pressure drop. Trinitex® is easy to process on rotary and knife pleating lines.

Microglass technology

Our Microglass technology guarantees consistent efficiency in the
final stage of air intake filtration – which ultimately protects the turbine. Microglass GT media are available in dual layer design, which provides increased dust holding capacity while maintaining the highest possible efficiency. Our Microglass GT media are the best media for static filter F7-F9 and HEPA filter applications.


Ahlstrom-Munksjö 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 taylored 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-Munksjö NanoPulse™

NanoPulse™ consists of our cellulose-synthetic 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.
NanoPulse™ can also be customized with value-added treatments such as fire retardancy.

Ahlstrom-Munksjö XAir 

XAir media combines the advantages of our
cellulose synthetic 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.
