MA Series
Polyethersulfone, Polypropylene, and Nylon Pleated Membrane Cartridges
EFI’s new pleated membrane cartridges are designed to meet the standards of a wide spectrum of industries. From our general grade pleated membranes designed for high purity applications at an economical cost to our integrity testable pharmaceutical grade membranes, these cartridges are manufactured to the most stringent production standards making them the new benchmark of the industry. Materials of construction are specifically chosen to match each application independently. The EFI cartridge should be your choice when absolute retention is essential to the process.
