WN Series Pleated Polysulfone Membrane Filter Cartridge

Composed of pleated highly asymmetric polysulfone membrane over a non-woven polypropylene support layer. For high flow rates and low pressure drops, absolute rated filters are designed for postfiltration in high purity water applications. The highly asymmetric membrane delivers longer on-stream life then conventional membrane products. High-purity construction materials are factory rinsed with DI water for quick on-stream rinse up with a minimum of throughput. All polypropylene parts and thermal welding minimizes extractables. All materials are FDA listed and meet criteria for USP Class VI Biological tests for plastics, ensuring that no surfactants or coatings interfere with the application.
