Clear and concise answers to FAQs begin with details of what an ePTFE membrane is, from the invention of PTFE in 1938, to the chemical formula for the PTFE molecule.
This is followed by definitions of terms such as needlefelt, a scrim and an epitropic fibre, and an explanation of effects such as hydrolysis.
From the basic question - What is a filter?, to descriptions of dust/air separation devices, such as cyclones, wet scrubbers and baghouses, to filter cleaning methods such as shaker, reverse air and pulse jet, many commonly asked questions are addressed.
This section also deals with the properties of Donaldson Membrane Tetratex Microporous ePTFE membrane filter media, available in four efficiencies: Tetratex Release, Tetratex, Tetratex High Efficiency and Tetratex Ultra High Efficiency, explaining how these high performance laminates supply superior dust cake release, low pressure drop, higher air flow, and high efficiency.
Issues such as how Tetratex membranes compare to other products and how they can be used in various applications are tackled, as are the definition and manufacture of nanofiber filter media for air and liquid filtration applications.
Most importantly the website provides the know-how to select and purchase the right kind of filter media for any application, delivering information with as little unnecessary technical jargon as possible.
For more in-depth information the website general filter media section provides an overall guide to Tetratex ePTFE films and laminates, and Ultra-Web Nanofiber filter media, for demanding applications in a wide range of worldwide markets.
