日本ドナルドソン List of Products and Services

Donaldson's "Tetratex Contact" is a filter that uses ePTFE (expanded polytetrafluoroethylene) membrane media, suitable for applications in pharmaceutical and food processing plants. "Tetratex Contact" complies with EU regulation 10/2011 and FDA GMP management standards, which are critical in the manufacturing process. According to standard test EN1186, it shows a dust passage amount that is significantly lower than the limits set by EU regulations. The manufacturing process varies depending on the application, and the selection of the appropriate filter media is a particularly important factor. "Tetratex Contact" offers a wide range of options to accommodate various applications.

PTFE (polytetrafluoroethylene) is specially processed to create a continuous porous membrane called "TetraTex Membrane," which has an extremely fine structure. Despite having very small pore sizes, it features a very high open area ratio. As a result, it excels in non-stick properties, self-lubrication, low friction, heat resistance, and chemical resistance. "TetraTex" is utilized as a "high-performance filter media" by laminating it onto substrates such as textiles and felt materials, and it is applied in a wide range of fields including next-generation energy, medical supplies, precision electronic components, industrial filters, and water treatment facilities. Enhanced Functions: - Breathability, filter bag life, dust collection efficiency, release performance Reduced Functions: - Exhaust dust, pressure loss, cleaning frequency, running costs, filter replacement frequency Case Studies: - Industrial bag filters (achieving high collection efficiency, release properties, durability, and cost-effectiveness) - Microfiltration (filters for various manufacturing processes such as dust, liquids, fermentation, sterilization, and process gases) - TetraTex Contact (FDA and EU regulatory certification. Filter material suitable for pharmaceutical and food processing applications)
