PTFE filter media contribute to emissions control

Published: 2-Feb-2005


Donaldson Membranes, part of the US-based Donaldson Company, has launched new filter media especially designed for applications involving high purity and high temperature gas/solid separation process.

Available in lightweight #7008 Tetratex High Efficiency woven PTFE fabric (pictured right) and heavyweight #7012 Tetratex Ultra High Efficiency woven PTFE fabric, both media complement Donaldson Membrane's portfolio of expanded PTFE membranes, films and laminates. Both the Tetratex ePTFE membrane and the woven PTFE substrate are manufactured from 100% PTFE resin, a chemically inert substance approved by the US FDA. Each can make significant contributions to emission control in industries where atmospheric emissions are subject to strict security and control by legislators and environmental groups. Tetratex membrane offers near zero emissions and exceptional dust cake release, allowing for higher airflow rates at reduced constant pressure drop. Available in the UK from Donaldson Filter Components, #7008 and #7012 are particularly suited to extreme chemical environments due to the inert properties of PTFE and its ability to operate at continuous service temperatures of up to 2600°C. Donaldson's patented #7012 exhibits tensile strength characteristics in excess of comparable PTFE needlefelt. #7008 is said to be ideal for the fine chemical, pharmaceutical and food manufacturing industries - where contamination of the product in contact with the filter media may occur – and is suitable for use in shaker and reverse air applications. #7012 is suitable for hot gas filtration applications where extreme chemical conditions may be present. These applications include the incineration of municipal or hospital waste, crematoria, industrial and commercial waste, sewage slurry, and other manufacturing processes, such as chemical and mineral processing.
