Protecting the Air We Breathe
In the world today, protection of the air we breathe 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, etratex® 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. It 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. 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. Tetratex® is a leading manufacturer and supplier of this technology.
Legislation: Emission of pollutant dust and fumes to the environment and work place are subject to ever more stringent legislative control and scrutiny, which has driven the demand for more efficient and effective filter media.
Cement: As a long-serving supplier to this well-established market, we have developed our products over many years of service in close co-operation with customers. Reducing energy consumption and CO2 emissions are two of the greatest challenges facing the cement industry today.
Fine Chemicals: Using our extensive product knowledge and technical expertise we are able to select the necessary products to achieve near zero emissions of expensive products, which can often be lost during the manufacturing process.
Incineration: As legislation evolves incineration plants are continually striving to reduce emissions. Tetratex® ePTFE membranes can provide near zero emissions which meet the required regulatory standards.
Food & Confectionary: As a recognized market leader in membranes we have gained invaluable experience in meeting the continually evolving and wide-ranging legislative requirements that govern the Food and Confectionary market, allowing us to deliver innovative solutions that meet your needs.
Plastics: Donaldson Membranes recognizes plastics as a valuable material, which is vital to many industries.
Metallurgical: The extraction, refinement and development of metals involve advanced processes, which require the sub micron capture capabilities of ePTFE membranes.
Non Metallic Minerals: Industries working with products such as cement, lime, coal and gypsum are subject to the most rigid standards when it comes to quality of product and environmental issues.
Pharmaceutical: In a market where new products and technologies are researched and developed at an ever-increasing rate, it is imperative that products used during the manufacturing process are of the highest caliber.
