G.Bopp Switzerland
G Bopp & Co AG is one of the world’s leading producers of precision woven wire meshes, These high quality wire cloths are used worldwide as square weave meshes for sieving and sizing, as stainless steel wire cloth for screen printing, as filter media and laminates as well as support meshes for a wide range of applications.

POREMET
This lead-like filter medium consists of five different wire cloth layers, put together so precisely that they achieve the optimum combination of stability, filter fineness, flow rate and backwashing properties. POREMET is particularly suitable for fine and finest filtration applications at high pressures and harsh operating environments.


Absolute filter fineness: 1–120 microns
Materials
- DIN 1.4404/AISI 316L, DIN 1.4539/AISI 904L
- Hastelloy alloys
- Other materials available on request
Application Recommendations
- Filtration of highly viscous liquids: Nutsche filters, centrifuges, fluidised beds, aeration of silos, applications in biotechnology.

ABSOLTA
- In contrast to POREMET, ABSOLTA N is ahighly porous filter medium developed to achieve increased flow rates at moderate pressures. ABSOLTA is particularly useful forits cleanability and backwashing capabilities. ABSOLTA D is also a five layer structure at a reduced thickness of 1.7 mm–1.8 mm.

TOPMESH 3
- In comparison with TOPMESH 2, this laminate features an additional bonded layer between the filter mesh and the square weave support mesh. Constant low flow resistance and good backwashing capabilities enable higher pressure loads to be handled. TOPMESH 3 is particularly suitable for use with CIP (Cleaning In Place) filters.


Absolute filter fineness: 1 – 530 microns
Application Recommendations
- As TOPMESH 2 as well as for sturdy aeration filters, Nutsche filter floors, spray driers, drying plant, container baskets for cleaning plant and filter drums for coolant lubrication equipment.
