Poromet® Cleanable Stainless Steel Filter Elements
                                                                 Custom & Standard Sizes
For high-temperature and high-corrosion processing applications.

For over 30 years, Purolator has been the recognized leader in porous metal filtration technology. With a variety of porous metal media to choose from, Purolator has met the stringent needs of customers in the aerospace, chemical processing, pharmaceutical, and nuclear power industries.  Purolator now offers these proprietary media in the Poromet® Series, a standard element product line designed for most commercial housings. 

Poromet® elements are designed for high-temperature and high-corrosion applications.  They are superior-quality filters whose performance exceeds every other competitive element. Poromet® elements are designed to lower your costs by providing on-stream life and years of trouble-free service. In addition, Poromet® elements are easily cleaned, eliminating growing disposal costs. 

Features/Benefits

  • Electron Beam Welded End Fittings. Purolator's exclusive electron beam welding process provides superior product quality at reduced costs. Heat distortion, oxidation, and sensitization are eliminated. The result is an element that is better able to withstand high temperatures, corrosive chemicals, and repeated cleanings. Poromet® elements are offered with double open ends, 1" NPT, or 222 double O-ring end fitting configurations.
  • Electropolished Butt-Welded Support Cores. Purolator-manufactured cores are designed to withstand pressures up to 250 psid. Electropolishing removes all metal burrs, so the filtered fluids pass through the element with less restriction.
  • Laser-Marked End Fittings. Each Poromet® Series element is permanently laser-marked for ease of identification and traceability.
  • Gaskets and O-Rings. Standard materials are Buna-N. Other compounds are also available.
  • 316L Stainless Steel. All Poromet® Series elements are made from 316L stainless steel filter media. They are ideal for temperatures up to 850° F and highly corrosive applications. Volume production makes Poromet® Series elements price-competitive with other elements made from lesser alloys.
  • Extended Filtration Area. Computer modeling optimizes the number of pleats and pleat height to maximize the filtering surface area. In fact, Poromet® pleated elements have over twice the filtering area as competitive elements. This means lower differential pressures, greater dirt-holding capacity and longer on-stream life.
  • Quality Control. Every Poromet element is bubble-point-tested prior to shipment to ensure product integrity and performance.
  • Standard Sizes. Poromet® elements are designed to replace standard stringwound and pleated media cartridges. They are offered in 2 3/8" diameter by 10", 20", 30" and 40" lengths.
Media Choices
Poromesh® media. Multiple layers of diffusion-bonded wire cloth are pleated to maximize filter area and on-stream life. Poromesh media capture contaminants on the upstream surface of the filter element, where it is easily cleaned or back-flushed. 
Porofelt® media. Microscopic, stainless steel fibers are random-laid and sintered in our proprietary diffusion bonding process. These media are then supported between two or more layers of wire cloth and pleated. Porofelt depth media traps particles deep within its complex pore structure. Porofelt elements provide finer filtration, with optimum dirt- holding capacity and permeability. 
Poroplate® media. A self-supporting medium made from multiple layers of woven wire cloth, sintered into a rigid, porous metal structure. Poroplate elements are cylindrical, surface type filters that are perfect for back- flushing and repeated cleaning. Because Poroplate elements are self- supporting, expensive filter support cores are eliminated.
