For more than forty years, Purolator Products Company has been a leading supplier of hydraulic filters and elements to the aerospace industry. These products were designed and manufactured with space-age materials and processes that provided cost-effective, dependable filter solutions. Along the way, Purolator led the industry in many important ways:

- We were the first filter company to employ microglass fiber technology to provide extended-life filter media. Today, our Microfil® III media continues to provide superior contaminant capacity and filter element life.
- We were the first filter manufacturer to adopt multipass testing as a way to characterize and define filter element performance. These test methods are considered industry standards today.
- We developed proprietary mathematical models which we use in the research and development of Microfil® III and other filter media. We continue to use these models to develop superior media for numerous applications.
- We pioneered the use of dynamic environmental test chambers to test filters at temperatures to -60° F., simulating flight conditions at extreme altitudes. This equipment is also used to predict filter performance in hostile environments on the ground.
- We installed a filter medial development laboratory which also includes a state-of-the-art Fordrinier media-making machine. We use this laboratory for empirical testing of our proprietary media, models and designs.
- We developed and produced some of the industry's first integrated filter systems, which include filter element bypass valves, differential pressure indicators and remote electrical switches. Today, our Microdelta® switches and indicators are specified by numerous aerospace and industrial OEMs.
- We developed and authored SAE Specification ARP901, "Bubble-Point Testing of Porous Media." This specification has become the industry standard specification used to determine a filter media's maximum pore size.

Now, Purolator brings its extensive hydraulic filtration expertise to the industrial fluid power market with a full line of filters, elements, breathers, strainers and accessories.

Spin-On Filters

Purolator invented the spin-on filter and continues to lead the industry today. Our industrial spin-on filters are designed to provide superior filtration performance and convenience.

Filter Elements

Elements are the porous devices that perform the actual process of filtration. Purolator offers a broad range of media to handle virtually any requirement. Read the details on our three major media types below.

Microfil® III media are made from micro-fine glass fibers which are randomly laid into a multilayered web. The media are impregnated with proprietary resins and thermally cured for strength and stability. They are engineered with tapered pore geometry to provide superior contaminant capacity.

Micropleat® media are made from resin-impregnated cellulose materials. The media are then pleated and assembled into economical Micropleat disposable elements. Micropleat elements are rated at Beta = 2 and are available in standard grades of 5, 10, 20, and 40 microns. They are designed and tested to withstand 150 and 300 psid collapse pressure.

Poromesh® media are multiple layers of sintered wire cloth which are pleated to maximize filter area and on-stream life. Our proprietary sintering process metallurgically bonds each woven wire to adjacent wires to maintain the desired micron rating of the media even under severe pressures. Poromesh media are made from 316L stainless steel wire meshes for excellent corrosion resistance and high temperature tolerance.

Breathers and Strainers

Purolator offers a full line of hydraulic reservoir breathers and filler breathers. These products filter the air which breathes into and out of the reservoir, helping to maintain hydraulic fluid purity.

Purolator suction strainers are used as coarse filtration on the suction inlet of the hydraulic pump. They are made of die-cast aluminum end caps, plated steel cores, and stainless steel filtration mesh.

Reservoir Elements

Purolator Facet micronic reservoir elements, utilizing 10 micron Micropleat® media, have higher efficiency and greater filtering area than any competitive product in this classification. This higher quality, lower weight, plus careful inspection and packaging, assures the user of maximum protection for hydraulc cylinders, pumps, valves or other closely fitted parts.

Switches and Indicators

MICRO DELTA® differential pressure devices sense the differential pressure directly across the filter element. At a preset limit, the indicator will actuate, signaling the need to change the filter element. This permits maximum use of the element, requiring element changing only when the full dirt holding capacity is reached, rather than changing elements on a periodic time basis which may result in premature disposal of "still useful" elements.
