Poroplate®
screen packs are multi-layer composites of woven wire mesh and/or
fiber metal felt. These media composites are diffusion-bonded
for high-pressure polymer filtration applications.
Poroplate® screen
packs are used in a variety of applications including polymer
film, fiber and bulk resin filtration. In addition to standard
discs and rectangular shapes, custom configurations such as conical
screen packs are also available.
Poroplate® screen
packs are typically recommended for filtration ratings from 5µ
- 40µ. Fiber metal felt media are typically included
in screen packs rated at 5µ - 40µ as a means of enhancing
gel retention or increasing screen pack onstream life.
Wires
in typical screen packs can shift under pressure resulting
in reduced filtration.
Each wire
is permanently bonded in place at every contact point
in Poroplate® screen packs.

Features
& Benefits:
No porosity
change. Poroplate® screen packs are metallurgically
bonded at every wire contact point, preventing wire movement
under high pressures. The result is consistent, reliable
filtration with no media migration or wire movement at high
pressures. Wire in conventional mesh screen packs may
shift under pressure, resulting in increased pore size.
Longer life.
Poroplate® media retain their pore structure at high pressures.
This enables the user to operate at higher pressures without
the risk of media migration or wire movement. When fiber
metal felt is used in Poroplate® media, onstream life can
be increased by a factor of 2 -3 times that of conventional
wire mesh media.
Enhanced gel
removal.
The permanent pore structure of Poroplate® media ensures
that gels are retained in the media. Bypassing of gels
because of wire mesh pore instability is eliminated. The
addition of fiber metal felt enhances the gel removal properties
of Poroplate® media and eliminates fiber breaks during spinning.
Low pressure
drop.
Compared with loose powder or sintered metal powder material,
Poroplate® media have 2 -3 times lower pressure drop at
equivalent micron ratings. This results in longer pack
life and less frequent pack maintenance.
Increased dirt-holding
capacity.
Poroplate® fiber metal felt media have 2 -3 times higher
dirt-holding capacity than conventional wire mesh media.
Pack life is maximized, resulting in less downtime.
