Donaldson Membranes to filter out the competition with market leading Tetratex r Media

at Powtech 2007, Nürnberg, Germany, 27th-29th March

Donaldson Membranes’ world-leading portfolio of Tetratex ePTFE filtration media will be on show at Powtech 2007, Hall 7, Stand 648.

Representatives from the mechanical process industry can take the opportunity to see how Tetratex(r) & ePTFE membranes can be tailored to meet the demands of difficult and critical applications in a wide cross-section of industrial markets and commercial product markets.

Visitors are also invited to a special cocktail reception at the Donaldson Membranes stand on Wednesday 28th March at 6pm.

Tetratex membranes for Industrial Products are ideal for a wide range of applications, including: cement, plastics, pharmaceutical, non-metallic, metallurgical and fine chemicals.

Tetratex expanded polytetrafluorethylene (ePTFE) membranes are manufactured
from 100% PTFE Polymer resin. They are chemically inert and thermally stable up to 287oC, and exhibit on average more than 100 million pores per cm2.

Tetratex is a surface filtration membrane, acting as a primary dust cake, requiring no dust cake to act as a filter aid, either before or during operation. It helps retain the substrate integrity by inhibiting dust particle penetration and restricting surface cake formation, maintaining optimum airflow and stable pressure drop.

Tetratex membrane filter media vastly improves the performance of
traditional filter fabrics which rely on the formation of a surface filter cake to capture fine dust particles, which can permit the migration of dust through the media leading to high emission values and raised pressure drop.

With emissions of pollutants into the environment and the workplace subject to ever more stringent legislative control, dust and fumes, toxic or not, must be removed from exhaust gases. In addition, the solid particulate carried in the gas or liquid flow often represents a useful or valuable product, which must be efficiently separated or filtered for final use or further processing.

The best control technology available to achieve these aims through the capture of fine particulate is recognised as fabric filter media utilising ePTFE membranes. The four efficiency levels of Tetratex(r) ePTFE membranes are: Tetratex Release; Tetratex; Tetratex High Efficiency Membrane; and Tetratex Ultra High Efficiency Membrane. Tetratex membranes deliver the highest particulate capture rates, unrivalled dust cake release, extended filter bag life and energy savings.
