Donaldson says that it wanted to add to the range of substrates available to customers.

According to the Donaldson, Tetratex EXTREME displays a significantly higher permeability to previous Tetratex membranes and delivers increased dust collector airflow characteristics and good particulate capture rates. The complex structure of the membrane ensures particulate emissions can be maintained at near-zero levels for the operational life of the media.

For use in industrial fabric filter applications, Donaldson adds that the aim of all its Tetratex ePTFE membranes is to maximise filtration efficiency, airflow and operational durability. The new EXTREME membrane enhances the Tetratex ePTFE membrane portfolio, and is available in polyester, polyester Antistatic, pleatable polyester, polypropylene antistatic, acrylic, acrylic antistatic, aramid, aramid antistatic, pleatable aramid, PPS, pleatable PPS, PPS antistatic and polyimide.
