It's easy to design a filtration system or a specific filter for your equipment using Allied Group's standard filter elements.

Our cost efficient replaceable filter elements are manufactured in a multitude of lengths, diameters and wall thicknesses, with excellent flow characteristics, making it easy for the customer to replace existing elements or having one designed for new equipment.

Our elements do not require support, and with end plates or baffles to guide the flow, they can be used without a housing. Elements are made of resin impregnated viscose cellulose material. Our process produces filters with exceptional heat tolerance and excellent corrosion and chemical resistance, with micron ratings of 75 down to under 1 micron. Efficient and effective filtration is assured with either an inside -out or outside -in flow. Liquids and gases are filtered as they pass through the graduated density network of intertwining fibers. Impurities are trapped throughout the entire depth of the element NOT just on the outer layer.

Our manufacturing process produces a high strength seamless self-supporting cylindrical filter with a graduated variable density, which leads to high efficiency depth filtration and high particle holding capacity.

We can manufacture dual density filter elements using different media or microns. This type of dual density filter replaces a pre-filter unit leading to longer service life.
