PES Membrane Filter Cartridges

Polyethersulphone membrane filter cartridges are designed to provide reliable sterilizing filtration for a wide variety of applications including water filtration, removal of spoiling micro-organisms in beverages, and filtration of pharmaceutical products.

Stringent quality control standards assure effective, consistent filtration performance and controlled pore sizes. PES membranes are inherently hydrophilic, and can therefore operate at high flow rates with a low differential pressure. Polypropylene support layers are present to provide mechanical strength and additional contaminant holding capacity.

The PES Symmetric Series consists of a single layer symmetric PES membrane.

The PES XL series consists of a single layer asymmetric membrane, providing a superior dirt holding capacity and therefore longer service life.

A special construction double layer version is also available on request consisting of one layer of symmetric and one layer of asymmetric membrane.

PES membrane cartridges are available with or without integrity testing prior to final packing depending on the needs of the application, and meet the requirements of FDA regulation CFR 177-82 , USP Class VI , and EC food contact directives
