WN Series Pleated Polysulfone Membrane Filter Cartridge

The WN series cartridge is an absolute rated filter for high flow rates and low pressure drops, ideally suited for postfiltration in high-purity water applications.


We offer a variety of filter cartridge replacements and housings to meet specific configurations and filtration needs. The WN series is a polysulfone membrane cartridge that is suited well for high purity applications.

This cartridge is composed of pleated highly asymmetric polysulfone membrane over a non-woven polypropylene support layer. High-purity construction materials are factory rinsed with DI water for quick on-stream rinse up with a minimum of throughput.  This design delivers longer on-stream life than conventional membranes.
