Electronics PTFE Membrane Cartridge Filters

Product catalog summary
Overview: ETM Cartridge Filters are designed for the electronics and high-purity chemical industries, utilizing a PTFE membrane that is resistant to most chemicals and suitable for filtering process gases. Pre-wetted options are available for high surface tension liquids, and the filters can handle elevated temperatures.
Construction Materials: The filters are constructed with a PTFE membrane, polypropylene media support, end caps, center core, and outer support cage. Sealing is achieved through thermal bonding, with various O-ring options including Buna, Viton, EP, Silicone, and FEP encapsulated variants.
Applications: These filters are suitable for compressed air, pressurized gases, solvents, tank ventilation, and chemicals.
Dimensions: The filters range from 5 to 40 inches in length with a nominal outside diameter of 2.75 inches. The filtration area is 7.0 ft² per 10-inch length.
Integrity Test Specifications: The filters are tested with a 60/40 IPA/Water-wetted membrane, with bubble points varying by pore size from 43 psig for 0.05 μm to 6 psig for 1.0 μm.
Operating Parameters: Maximum differential pressure is 50 psid forward and 40 psid reverse at 20°C. Operating temperature is up to 82°C at 10 psid. Recommended changeout pressure is 35 psid.
Sanitization/Sterilization: Filters can be autoclaved at 121°C or steam sterilized at 135°C. Chemical sanitization is possible with standard chemicals.
Performance and Quality Assurance: Critical Process Filtration, Inc. ensures high-quality manufacturing meeting ISO 9001:2008 standards, with operations conducted in clean rooms and real-time data analysis for quality improvements.
Ordering Information: Cartridge order numbers vary by pore size, end cap type, length, and O-ring material. Flow rates for liquids and gases are provided for different pore sizes.
Extractables: E-grade filters have low extractables, with aqueous extracts below 3 ppb TOC after rinsing.

ETM Cartridge Filters PTFE Membrane Pressurized Gases Tank Ventilation Dimensions Length Outside Diameter Filtration Area Integrity Test Specifications 60/40 IPA/Water-wetted membrane 0.05 μm ETM Filter Cartridges are designed to meet the special needs of the electronics and high-purity chemical industries. Polytetrafluoroethylene (PTFE) membrane is resistant to virtually all chemicals. Because of the hydrophobic nature of PTFE, it can also be used to filter process gases. Pre-wetted ETM filters are available for liquids with surface tension too high to wet out PTFE membrane. This membrane will also handle elevated process temperatures in compatible fluids. To minimize extractables, each cartridge module is pulse power flushed until the rinse effluent reaches 18+ Megohm-cm and less than 3 ppb TOC. Each cartridge module is also individually tested for integrity.
