Porvair Polymeric Membrane Filters Meet Stringent International Guidelines

Porvair Filtration Group, a world leader in filtration and separation technologies, has announced its range of polymeric membrane filters is proven to meet the most stringent international regulatory guidelines.

Filtration and separation processes in the Pharmaceutical and Food & Beverage industries are critical, not only to ensure products are adequately purified and fit for consumption, but also to optimise process economics and prevent loss of valuable product. Membrane cartridges can be used as pre-filters or final filters and are suitable for particulate or microbial reduction in critical applications.

Foremost to achieving high performance filtration is the rigorous construction of Porvair pleated membrane cartridges which ensures higher flow rates, lower pressure differentials and faster process times. Independently verified to meet USP Class VI and ISO 10993, each filter is provided with a certificate of quality. Manufacturing takes place in an ISO Class 5 clean room in accordance with accredited quality procedures and the membrane is protected from damage during production by the inner and outer drainage layers that maintain the pleat pack structure.

Designed to withstand pressure during filtration, the filter's inner core comprises a thermoplastic material that further supports the pleat pack and draws the filtrate through its perforations to the outlet of the cartridge. Snugly encased in a polymeric outer cage and securely fitted with sanitary design adaptors that provide optimal sealing and safety against bypass, each cartridge is uniquely identified by a serial number embossed on the outer sleeve providing full traceability to all FDA CFR 21 and EC-approved manufacturing components. The supply chain is closely monitored with in-house production of the filter's outer cage, core and end cap. Careful attention to package design minimises the chance of damage to the filters during transit and storage.

Assurance of the high quality of Porvair membrane cartridge filters is further demonstrated by post-manufacture integrity testing, a non-destructive means of determining oversized pores or defects that compromise a filter's retention capabilities.

The integrity test parameters employed by Porvair are correlated to the filter's microbial retention capabilities as determined during validation in accordance with ASTM F838-05, HIMA and PDA Technical Reports 26 and 40. Any filter that fails integrity testing is immediately discarded. Through continued investment in state-of-the-art manufacturing techniques, Porvair look to develop high quality, cost-effective filters that meet or exceed regulatory standards and industry demands.

Porvair Filtration Group is an international leader in the development and supply of materials and products for applications in filtration and separation. Their expertise in a wide range of media and the dedication of their design, manufacturing, sales, test and research teams ensure they are at the forefront of filtration technology, delivering world class performance to the Aerospace, Defence, Nuclear, Energy, Chemical Process, Industrial Process, Water Treatment, Printing and Life Science markets.
