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
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 guarantees 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.
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.
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.
Ahlstrom cellulose-synthetic blend
This blended media 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.
