1 Gas turbine air intake media

2 Gas turbine air intake fiter media soutions High energy cost and demand wordwide have increased the focus on energy efficiency in many industries and market sectors. Specificay, the Power Generation sector is driven by the need for affordabe eectricity. One key contributor to energy efficiency are Air Intake systems of Gas Turbines. This step of the power generation process takes a ot of energy to produce the cean air required for turbines to operate. As Gas Turbines are instaed in many different environments wordwide, the requirements for air intake fiter systems and the seection of the correct fiters become crucia for the production of affordabe energy. Ahstrom s soutions for gas turbine air intake fitration are based on severa technica patforms. Our expertise and atest knowhow in various nonwoven technoogies and chemistries is appied to provide severa advanced soutions to the fiter manufacturers. The media technoogy utiized and the seection of the fiber composition and resin chemistries are carefuy chosen according to the specific fiter performance requirements. Our fiter media can be used in: Peated fiters for pre-fitration Peated bank and cartridge fiters for primary fitration Peated fiters for HEPA fitration Fu range of technoogies and benefits - Ahstrom is a singe source provider of fiter media soutions for both static and puse-jet gas turbine air intake appications. Ahstrom Trinitex GT Ahstrom Trinitex GT technoogy offers fiter media with exceent mechanica fitration efficiency and ow pressure drop thanks to its unique 3-ayer structure. Each ayer can be customized to deiver specific properties and the optima combination of strength, mechanica partice remova efficiency even at sma partice sizes, and pressure drop. Ahstrom Trinitex GT is easy to process on rotary and knife peating ines. Ahstrom Microgass GT fiter media Our Microgass technoogy guarantees consistent efficiency in the fina stage of air intake fitration which utimatey protects the turbine. Ahstrom Microgass GT media is avaiabe in dua ayer design, which provides the media with increased dust hoding capacity whie maintaining the highest possibe efficiency. Our Microgass Gt media is the best media for static fiters F7-F9 and HEPA fiter appications.

This step of the power generation process takes a ot of energy to produce the cean air required for turbines to operate.

3 Ahstrom offers a compete range of Gas Turbine Air Intake fiter media to meet the specific needs in various operationa environments. We offer soutions for a stages of fitration - from pre-fitration to fina stage HEPA fitration or puse jet fitration. Effective air intake fitration is critica in order to protect gas turbine bades and maximize the ifespan of the turbines. Different cimate conditions deiver intake air at different temperatures and with different contamination, which makes the seection of the correct air intake fiter media crucia. Benefits Compete range of media from 100% ceuose to 100% synthetic or microgass in various combinations for a stages of power generation air intake fitration Fiter media designed to offer soutions for a variety of operationa environments and temperatures: high humidity, sand, sat, soot, dust, fog, snow and others Abiity to tayor-make products according to your specific performance requirements: A singe source for a fiter media soutions

4 Ahstrom SafePuse Our portfoio of corrugated media for reverse-puse appications covers materia compositions from 100% ceuose over the famous 80/20 media to 100% synthetic soutions, and efficiency eves from M5 to F9 according to EN and EN We offer media with various physica properties tayored to our customers individua 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 optiona vaue adds such as fire retardancy. Ahstrom XAir GT Ahstrom s XAir GT media combines the advantages of our SafePuse media and our Fine Fiber Metbown technoogy to deiver a media with exceent reverse-pusing properties as we as high dust hoding properties for extended puse cyces. Ahstrom NanoPuse Ahstrom NanoPuse consists of our SafePuse media coated with eectrospun nanofibers on the upstream side. This structure resuts in exceent reverse-pusing behavior and high mechanica efficiency at the owest possibe pressure drop. Like our SafePuse famiy, NanoPuse can aso be customized with vaue-added treatments such as fire retardancy.

5 Ahstrom media portfoio for gas turbine air intake Trinitex GT Pre Fiter Primary Fiter Trinitex GT is an Ahstrom proprietary technoogy that produces fiter media with 3 ayers, which are customized for the specific needs of Gas Turbine Air Intake fitration. With high strength thanks to synthetic fibers and superior performance in diese soot, Trinitex GT can be used in both, static and puse jet appications and is we suited for environments with high humidity, soot and sat. HEPA Fiter Microgass GT Pre Fiter Microgass Gt fiter media is avaiabe in singe or dua ayer design, with great fexibiity to incorporate additives or synthetic fibers for enhanced strength or peatabiity of the media. Microgass GT media is suited for fiters as used in various environmenta conditions. Primary Fiter HEPA Fiter Ahstrom SafePuse Pre Fiter Primary Fiter HEPA Fiter Ahstrom XAir GT Pre Fiter Ahstrom XAir GT fiter media is a famiy of products with a fine ayer of Fine Fiber on top of a ceuose carrier sheet. Ahstrom XAir GT offers superior fitration efficiency and dust hoding capacity thanks due very fine ayer of sma fibers upstream. High corrugation aso heps the ceaning process. Primary Fiter HEPA Fiter Ahstrom NanoPuse Pre Fiter Ahstrom NanoPuse fiter media consist of a SafePuse base sheet coated with true eectrospun nanofibers. Depending on the media design, a wide range of fitration performance characteristics can be achieved. Primary Fiter Ahstrom SafePuse fiter media consists of ceuose, poyester and/or microgass fibers. Typicay corrugated to aid peat separation and dust cake reease, our SafePuse portfoio was deveoped around the traditiona 80/20 media with 20% PET fibers. Thanks to its exceent reverse-pusing behavior in dusty environments, it is the standard media used for pre- and primary fitration of reverse-puse fitration systems. HEPA Fiter
