概要
Rigimesh medium is a sintered, woven-wire-mesh product having the greatest permeability for comparable removal efficiency. Sintered in a high temperature vacuum furnace, the wires are bonded at every point of contact to produce an extremely strong metallic medium with wires that will not shift under stress; thus the pore size and integrity is continuously maintained. Since sintering increases mechanical strength of the woven wire mesh media, this patented Pall process permits the use of finer diameter wires in manufacturing the medium.
We have the ability to sinter multi-layer composites of different meshes on special order, and to meet application needs for precise flow, pressure drop, thickness, or strength.
Major Advantages
Features
- Controlled pore size with a sharper particle size cut-off than depth filter media
- Finer sinter-bonded woven wires
Benefits
- Assured absolute particle retention
- Long on-stream life
