Cleanable Media Products
• Porofelt® Media • Metaledge® Media •
| Poroplate®
products are commonly manufactured from 600x1200 mm panels.
These panels may be trimmed into smaller sheets or discs, stamped
into custom shapes or formed into cones or cylinders. Larger sheets
are produced by welding several panels together.
Inherent adaptability makes Poroplate® media the perfect material for a wide variety of applications. Poroplate® panels, tubes and discs make excellent filters for tough industrial environments. Tubes and cones are used to fluidize dry granular materials such as cement and polymer pellets. Specialty constructions have even been used in noise suppression, transpiration cooling, vacuum forming and dewatering. Poroplate® laminates are as versatile as you need them to be.

| Poromesh®
filter media is made from layers of diffusion-bonded wire
cloth. This material is pleated to maximize filter area and the service
life of the filtering element. Poromesh®
elements are typically used in hydraulic, fuel, gas, polymer and chemical
filtration.
Poromesh® media is made from 304 or 316 stainless steel as well as more exotic alloys like Monel and Inconel. This pleated media can be formed into cylinders or stamped into discs. The multilayer pleated construction makes Poromesh® elements particularly suited for rugged usage. The pleating provides maximum filtration area, flow distribution and dirt capacity. Support meshes prevent collapse and bunching of the pleats at high differential pressure. Yet a Poromesh element is easily cleaned for reuse. |

| Porofelt®
media is Poromesh®
media comprised of stainless steel fibers that 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®
elements provide finer filtration with optimum dirt-holding capacity
and permeability.
Poromesh® and Porofelt® elements are available in almost every size imaginable from 3mm discs to cylinders over 1 meter in length, each custom designed for your unique application. |

| Poroloy®
products are seamless tubes of precisely wound calendered
wire designed for demanding aerospace and industrial applications
such as filtration, noise suppression and transpiration cooling.
Cylinders are wound from 347 stainless steel wire of .07 to .13mm, although larger wire and ribbons of special alloys (Monel, Hastelloy®, titanium and more) may be used. Winding machines are computer-controlled to lay down wire spacings and geometries that establish filtration ratings of 10, 20, 40, 75 and 100 micro m. Other ratings are easily accommodated. Flow resistance is controlled by the configuration of the wind
pattern. The pore may be designed to produce a tortuous path (excellent
for fine filtration), a straight-through path (for greater permeability)
and anywhere in-between. |
 |
| After winding, Poroloy® cylinders are
furnace sintered to diffusion bond all the wire contact points. The
resulting unit is strong, ductile and corrosion resistant.
Poroguard® filters are produced by placing woven wire cloth (or other filter media) within the wall of a Poroloy® tube. The wire cloth acts as the filter medium while the wound wire provides strength and protection for the mesh. Poroguard® elements are recommended for demanding applications requiring absolute filter ratings and high throughput. Poroloy® and Poroguard® cylinders are available in a broad
range of diameters, lengths and thicknesses. |

| Metaledge®
Self-Cleaning Media - Wedge shaped stainless steel ribbon
with raised projections, wound edgewise on a cylindrical frame, and
scraped by a knife edge. The knife edge removes the contaminant from
the surface of the element, and is drained periodically from the sump.
Metaledge® filters have been designed to filter the most viscous
of fluids. Standard sizes are available from 3/4" NPT to 4" flange
connections. 10 different micron ratings are available from 25 to
500 micron. Housing are available in carbon steel or 304 stainless
steel with stainless steel elements. |
|
| How Does It Work? The Metaledge® filter medium consists of a wedge shaped metal ribbon with projections, wound edgewise on a cylindrical frame that is slotted or perforated. Flow is from the outside in. The openings between the wire winding and the degree of filtration are accurately and permanently established by the height of the projections. The wire is preformed to a wedge shape prior to winding to produce a tapered flow path opening inward. Particles larger than the openings between the windings are stopped at the outer surface where they are easily removed by a cleaning knife. The knife is either manually turned by rotating a handle, turning the knife around the element; or by a motor which rotates the element against a stationary knife. The sump may be purged periodically to remove any contaminant. | |
