In the world today, protection of the air we breath and of the environment in which we live and work are subject to ever-increasing scrutiny by economic and political groups.

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

Tetratex membranes are thermally bonded onto a range of substrates including woven, spun bonded and needlefelt materials which are utilized in pulse jet, reverse air and cartridge type dust collectors and filter baghouses.

Tetratex is a surface filtration membrane. It acts as a primary dust cake, requiring no dust cake to act as a filter aid, either before or during operation. Tetratex 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.

Tetratex delivers high particulate capture rates, excellent dust cake release, extended filter bag life and energy savings.

All dust and fumes, whether toxic or not, may be hazardous to health and the environment and must be removed, reduced or suppressed to provide an atmosphere in which all may live and work in safety.

Governments are responding by imposing stringent limits to pollutant emissions from manufacturing and other processes.

For pollution control devices employing fabric filter media, the best available control technology for the capture of fine and difficult particulate is recognized by industry experts as media utilizing ePTFE membranes.
