Purolator - Who are we?

Purolator is a name synonymous with quality filtration throughout the world. From its humble beginnings in 1927 when a lampshade spawned the idea of a pleated filter (Purolator was the originator of the corrugated or pleated design), the company has evolved to offer a complete line of products for virtually all industrial sectors. Purolator Facet, Inc. is a division of .

Purolator Facet, Inc. is a creative engineering and manufacturing organization offering fluid mechanics and porous media technology to address specific needs for diverse markets. A host of custom and standard products is available for fluid filtration, fluidization, acoustic attenuation, separation, transpiration cooling and many other applications. 

Greensboro, North Carolina is the home of Purolator Facet, Inc. Our facility is located on 10 acres just seven minutes west of the Greensboro, Winston-Salem, High Point airport (Piedmont Triad International) in the Triad Industrial Park. The energy efficient 90,000 square foot facility has been designed to meet all of the requirements for the best work flow patterns, environmentally controlled areas, and increased productivity.   An additional 65,000 square foot manufacturing building is located one mile from our main plant.

Spin-On  Filter Elements & Heads 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.  They're readily interchangeable with most competitive filters.  Maximum operating pressure 100 psi.

Hydraulic 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

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 a tapered pore geometry to provide superior contaminant capacity. Larger pores are located on the upstream surface, with finer and finer pores in the depth of the media. This proven media design philosophy gives Microfil III superior on-stream life versus competitive elements. All Microfil III elements are designed and tested to provide Beta > 200 filtration efficiency. Microfil III elements are offered in standard grades of 3, 6, 12 and 20 microns. They are designed and tested to withstand 150 and 300 psid collapse pressure, while Hi-Collapse Microfil® III is designed to withstand 3,000 psid.          

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. The elements are electron beam welded—a Purolator exclusive. This process eliminates heat distortion, oxidation, and sensitization, providing superior product quality at reduced costs. Poromesh elements are rated at 2, 5, 10, 20, and 40 microns nominal and are designed to withstand 150, 300 and 4500 psid collapse pressures. For 4500 psid elements please contact Purolator.
