Gas Turbine Air Intake

Best performance for all challenging environments
Complete range of Gas Turbine Air Intake filter media
Available for both pulse-jet and static applications - your single source provider of filter media
Gas Turbine Air Intake
A complete range of Gas Turbine Air Intake filter media to meet the specific market needs in various operational environments.

We are a single source provider of filter media solutions for both static and pulse-jet gas turbine air intake applications. Covering the full range of filter class, our products deliver the following key benefits:

  • High level of particulate removal efficiency available for both static and pulse-jet applications delivering better protection of the turbine against fine dust, soot and salts
  • Optimal level of pressure drop regardless of efficiency class and product family – helping to maximize output and minimize energy consumption
  • Longer filter lifetime: optimised self-cleaning properties (pulse-jet) and extended dust holding capacity (static)
  • High level of hydrophobicity across the portfolio preventing liquid water ingress through the filters and extending lifetime in humid environmental conditions



To cover all the different environments and performances, we offer a wide technology portfolio for Gas Turbine applications.   


Ahlstrom Trinitex® GT

A technology which offers filter media with excellent mechanical filtration efficiency and low pressure drop due 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.


Ahlstrom Trinitex® Advance GT

A unique platform product, which is designed to Purify Air in Industrial Filtration applications.  From this platform, a family of products will be built over time, delivering defined customer benefits in different market sectors.

Ahlstrom Glass GT

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


Ahlstrom Nano GT

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. Nano GT can also be customized with value-added treatments such as fire retardancy.

Ahlstrom FineFiber GT

Combines the advantages of our cellulose synthetic media and our fine fiber meltblown technology.  It delivers a media with excellent reverse-pulsing properties as well as high dust holding properties for extended pulse cycles. 


Ahlstrom CellTech GT 

Is a blended media and is available in different basis weight and cellulose-synthetic ratios.  It has good mechanical strength and pleating behaviour on rotary machines and deep corrugation offers optimum pleat separation.


Ahlstrom Synthetic GT

Is based on our CellTech platform with a fully synthetic fiber composition and an hydrophobic treatment.  The self-supported structure is designed for pulse-jet applications, combining best pleatability, excellent durability and very good performance for filtering coarse particles.
