Rigimesh® Filter Elements

Rigimesh® porous metal filter elements are extremely permeable and are constructed of high dirt capacity stainless steel (type 304 or 316L) woven wire mesh. Rigimesh media outperform other meshes because they are sintered woven wire meshes with higher void space. Pall sinters the wires at their points of contact, producing an extremely strong porous material whose wires will not shift under stress and whose pore size integrity is continually maintained. This patented Pall process permits use of finer diameter wires in manufacturing the filter medium. The net result is a filter with more pores per unit area, providing more dirt-holding capacity than that of an unsintered mesh made from coarser wires. Designs are available which are suitable for temperatures up to 600°F/315°C.

Table I. Rigimesh Elements and Their Characteristics



^ Threaded connector series only. Due to seal limitations, 1000 Series suitable for applications up to 450°F.
* Supramesh sintered powder metal and mesh composite medium.
1Liquid removal efficiency ratings are based on hard spherical particles.
2Weight percent removal data is based on AC Fine Test Dust in air. Absolute retention ratings are calculated values.
3Pressure drop in psi obtained by multiplying value shown by actual flow desired in gpm, viscosity of liquid in centipoise (if other than 1 cp), all divided by total filtration area (ft2) selected. See Table II for areas.
4Pressure drop in psi obtained by multiplying value shown by actual gaseous flow rate desired (acfm), ratio of viscosities
actual cp of gas
0.018 (viscosity of air)
all divided by total filtration area (ft2) selected. See Table II for areas.
