Filter Klear AquaKey combines industry renowned Filter Klear GIANT sediment filtration with innovative UV Pure ultra-violet water purification to provide the ultimate in water safety.

Engineered Designs for Liquid and Air: At Keystone Filter, we"re specialists in providing pleated custom filter media and cartridges designed to solve a wide variety of industrial filtration problems including air, liquid and gas filtration.

Manufactured from randomly laid metal fibres, sinter-bonded to form a uniform high porosity filter medium, Sinterflo F demonstrates a significantly low pressure drop, high permeability and excellent dirt holding capacity. Moreover, sintered metal fibre may be pleated to increase the available filtration area of a filter element, thereby further increasing dirt holding capacity and so minimising maintenance and maximising on-stream processing.

A robust material manufactured from sinter-bonded metal powders. Primarily produced in 316L grade for use in temperatures up to 540ºC (1004ºF), depending on process conditions, and offering resistance to most chemicals, Sinterflo P media can also be produced in other grades of stainless steel and alloys such as Inconel, Hastelloy and Monel. Sinterflo powder media can be manufactured in both disc format or in cylinder format. For cylinders, our isostatic pressing ensures greater media uniformity with no welds, leading to increased corrosion resistance.

Activated carbon, a porous substance with strong physical adsorbtion properties, has the highest volume of adsorbing porosity of any material known.

Cryptofil filter cartridges are utilised for the control of Cryptosporidium oocysts in the water used in the food, beverage and ultrapure water industries.

A range of absolute rated cartridge filters from Porvair Filtration Group, featuring the latest developments in meltblown polypropylene filter media technology, Klearfil cartridges are based on a robust all polypropylene construction, offering removal ratings from 0.5 to 75 micron absolute.

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.

Porvair Biofil 1 cartridges utilise a single layer of polyethersulfone (PES) membrane, providing a filter with effective bioburden retention properties to support the manufacture of food and beverage products.

A range of microbially rated cartridge filters from Porvair Filtration Group, featuring the latest developments in membrane technology, Biofil™ II 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 of consistently precise microbial retention.
