GTM Filter Cartridges are designed for general purpose usewherever a hydrophobic membrane filter is required. Manufacturedwith inherently hydrophobic polytetrafluoroethylene (PTFE)membrane, these cartridges are designed for use in the filtrationof aggressive solvents, and as compressed gas and vent filters.These cartridges are found in the manufacturing processesof firms in multiple industries that require high quality, costeffective filter technologies. The cartridge surface area, filter coredesign, pleat configuration, and pleat packing density have beenoptimized to provide increased cartridge life resulting in lowerfiltration operating costs.
