Gas turbine filtration and dust collection systems operate in the most challenging environments imaginable. They require high service intervals and durability against airborne contaminants found in adverse conditions throughout the world. H&V offers the broadest range of pulse-cleaned and static high-performance filter media that set the standard for efficiency and extended life in the toughest environments.
- Patented NanoWeb® media offers 500% higher service intervals for pulsed cartridge applications compared to non-fine fiber treated media. Our media offers the ability to fine-tune filter change intervals to match up to your other maintenance timelines.
- Our market-leading corrugation capabilities (> 20 mils) offer superior dust-holding capacity for lower-cost, higher-service interval filter designs.
The filters in today’s gas turbine intake and dust collection systems must comply with an increasing number of demanding market needs. As the innovative materials leader, H&V offers several products to fulfill your requirements:
- NANOWEB media greatly improves a filter’s ability to remove particulates from air streams, making it highly attractive for gas turbine filtration and dust collection applications. Durable flame retardants (FR) meet the newest OEM requirements.
- H&V glass media for stationary gas turbine filter systems are available for efficiency requirements from M6 to H13 (EN779:2012/EN1822) or from MERV 8 to MERV 15 (ASHRAE 52.2). In case of high humidity applications (coastal and off-shore), special media in the above efficiency classes are also available.
- H&V synthetic media for stationary gas turbine or pulse-cleaning applications in the MERV 11 to MERV 15 range improves durability and lifetime.
No curing ovens are required for processing pre-cured acrylic system designs, enabling smaller filter processing line footprints and saving energy. And, our newest design and manufacturing processes provide greater roll-to-roll and lot-to-lot consistency, giving you easier pleater set ups and a more optimized production process. With mills in the U.S., Mexico, Germany, U.K., and China, H&V provides globally consistent products and short supply-chain lead times.

Frequently Asked Questions
Q) Do I need to cure H&V gas turbine air filter media?
A) If your media uses acrylic based resins and is identified as “low energy”, then the media is already cured sufficiently for the application it was designed for. Additional process warming, either through hot plates, IR heaters, or ovens may be used if desired to better optimize processing without harming the media.
Q) What is a wire side mark?
A) A wire side mark is a line that H&V puts on the downstream side of the media to indicate which side should be oriented to the ‘clean’ or downstream side of the air flow. The wire mark color and spacing is specific to an individual grade, but standard spacing is on two inch centers, and standard colors for the line mark are either black or blue ink.
Q) What is the usual test standard used to evaluate gas turbine air filter media?
A) ASHRAE 52.2 and EN779 (2012) are the two globally accepted test standards for either flat sheet or element evaluation of HVAC and gas turbine air filter media or filters.
Q) Which grades are best for pulse cleaning gas turbine applications?
A) H&V has developed the NANOWEB® range of filter media that is expressly made for pulsing applications. The NANOWEB layer is positioned on the dirty or upstream side of the cartridge where it promotes rapid dust cake formation. The rapid formation of the dust cake promotes a very complete pulse cleaning of the cake from the cartridge. This allows an optimized filter service interval and high MERV rating (13 to 15) or F rating (8 to 9) that cannot be obtained without use of nanofibers.
