Ahlstrom’s solutions for gas turbine air intake filtration 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 the filter manufacturers. The media technology utilized and selection of the fiber composition and resin chemistries are carefully chosen according to the specific filter performance requirements.
- 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 and others
- Ability to taylor-make products according to your specific performance requirements
Ahlstrom offers a complete range of Gas Turbine Air Intake filter media to meet the specific needs in various operational environments. We offer solutions for all stages of filtration - from pre-filtration to final stage HEPA filtration or pulse jet 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 customized 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.
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 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™ 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 customized with value-added treatments such as fire retardancy.
With the full range of technologies, Ahlstrom is a single source provider of filter media solutions for both static and pulse-jet gas turbine air intake applications.
