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.
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.
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.
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.
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
- 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.
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.
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.
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.
