Pneumafil has developed a unique filter media called Matrex^TM which offers dramatically improved initial efficiency, particularly at submicron particle sizes. The improved efficiency provides cleaner operation for the compressor section of combustion turbines and reduced compressor washing cycles, resulting in direct cost savings to turbine operators.

Over the past several years, pulse style inlet filtration systems have become widely used, even in temperate environments with relatively low ambient dust concentrations, because major turbine OEMs have used the pulse style as their standard inlet design. In those environments— where it takes a long time to develop a dust cake on the pulse cartridge — it is important to have a high initial efficiency to avoid fouling the compressor section of the turbine.

Pneumafil's Matrex medium (shown at 500X magnification below) combines a robust cellulose /polyester blended base material with a synthetic nanofiber layer on the dirty air side. The microfiber layer in Matrex media dramatically increases the initial collection efficiency on small particles without increasing the initial resistance of the complete cartridge assembly. The efficiency of this new media surpasses all OEM minimum filtration efficiency requirements as well as that of competitive cartridges with “membrane” or other fine fiber layers on the dirty air side.

Pneumafil’s Matrex media is now available in all pulse style cartridge filters.
