Porvair Filtration Group has won a two-year supply agreement for its Polyfil II and Aquafil disposable filter cartridges from a leading PTFE manufacturer, to produce large quantities of particulate-free water at low cost.

Polyfil II cartridges are the filter of choice for the absolute removal of unwanted particulates (0.5 to 105 micron) and for prefiltration to membrane filters. The pleated polypropylene high surface area design of Polyfil II cartridges helps to achieve lower running costs and a smaller process footprint.

Polyfil II cartridges are highly resistant to integrity failure caused by steam sterilisation and have excellent chemical compatibility characteristics. Aquafil polyethersulphone membrane filters are ideal for use on high flow recirculation water systems where the water passes through the filter many times.
