Aquafil™ Single Layer Polyethersulphone Membrane Cartridge Filters

A range of cartridge filters from Porvair Filtration Group, featuring the latest developments in membrane technology, Aquafil™ cartridges are based on a naturally hydrophilic polyethersulphone membrane with a mirrored asymmetric pore structure. When combined with quality all-polypropylene cartridge components and high integrity manufacturing techniques common to all Porvair cartridge filters, the polyethersulphone membrane provides a high strength, long life cartridge.

Aquafil™ cartridges exploit the narrow pore size distribution and high void volume of the media to provide a choice of cartridges capable of meeting the requirements of most applications. Careful media selection ensures that Aquafil™ cartridges are suited to retention down to 0.2 micron ratings. Aquafil™ cartridges offer high flux rates and low differential pressures, a feature common to polyethersulphone membranes.

Aquafil™ cartridges benefit from the low non-specific protein binding characteristics of polyethersulphone membranes. They are also resistant to steam sterilisation and have excellent chemical compatibility characteristics. Furthermore, since they will not hydrolyse, Aquafil™ cartridges are ideal for use in ultra-pure water supply systems (18MO.cm).

As a consequence Aquafil™ cartridges provide a combination of features and benefits not hitherto available from cartridges based on PVDF, nylon, mixed esters of cellulose or polysulphone membranes. They are suitable for applications ranging from bioburden reduction and the clarification of a wide range of process liquids and end products.
