GAS TURBINE INLET AIR MEDIA
Fibertex nonwovens with nanofiber coatings, are suitable for both surface loading pulsable cartridges and depth filtration filters in gas turbine air inlet systems. Filtration efficiencies range from Iso Coarse / MERV 10 with standard polyester nonwoven and optional hydrophopic, oleophopic and antistatic treatments, to E11 / MERV 17, with a durable nanofiber coating.
Fibertex nanofiber coatings have exceptional filtration efficiency properties, with excellent dust cake release and minimal energy required for back pulsing. Nanofiber coatings can be applied into pleatable polyester nonwovens and cellulose/polyester blends.
The nanofiber coating provides a true surface filtration, which is approximately 15 times thinner than similar efficiency ePTFE materials. The fine and highly-effective nanofiber coating is resistant to contamination from small particles and has twice the air permeability to help back-pulsing, compared to the same efficiency ePTFE layer. The end result is extended filter life and savings in energy for back-pulsing.
Fibertex depth filtration media for gas turbines have a gradient structure, comprising an initial pre-filter layer, a dust holding layer and the final nanofiber layer.
