Polygard®-CN products are nominally rated filters designed for particle removal applications in liquids and gases. The pleated structure of Polygard®-CN filter media minimizes pressure differentials during the filtration process, and the all-polypropylene construction of these filters conveys low levels of extractables and broad chemical compatibility. Downstream filter performance is enhanced due to efficient particle and microorganism reduction.
Polygard®-CN cartridge filters provide high throughput with minimal differential pressure. Cartridges are robust, strong, resilient and are designed to withstand multiple steam-in-place cycles.
Polygard®-CN cartridge filters are widely used in the beverage industry for liquid and gas filtration applications, for fining operations and bioburden reduction.
Polygard®-CN filters are designed, developed, and manufactured in accordance with a Quality Management System approved by an accredited registering body to an ISO® 9000 Quality Systems Standard and are shipped with a Certificate of Quality. Each cartridge filter is supported by a Validation Guide for compliance with regulatory requirements.
For traceability and easy identification, each filter is marked with identifying characteristics.
Multiple Formats Available
A full range of filter sizes is available to suit your application requirements. A variety of connection options are offered for easy adaptation to existing housings.
