After screen printing, filtration is the most important application for BOPP meshes. Today’s filter meshes and mesh combinations are the result of intensive research combined with the experience of countless different applications in diverse industrial sectors. The best filtration results can only be attained by achieving the optimum balance between the differing elements: premium quality materials, primarily stainless steel, fault free meshes, accurate handling and a comprehensive under standing of filtration processes in the most diverse applications.
Q Optimum results with steel filter mesh
Using our meshes is your guarantee of secure and economical filtration results. As of the first flow of gases and liquids contraining solids, the mesh will screen out all particles larger than the pores from the solids-bearing gases or liquids. These remain on the mesh surface and, with time, build up a filter cake, which works as a further filtration medium. The filtrate is removed when it becomes too thick or too compacted. Accurate pore distribution results in regular build up of filter cake, and the smooth surface of our meshes guarantees good cake release and backwashing properties.

Q Properties and advantages of BOPP meshes:
Advanced stability Flat surface structure High resistance to abrasion Regular pore distribution Narrow pore size allocation Good plasticity Good flow rates No particle detachment Chemical and thermal resistance Easy to clean Advanced reliability
Q Filter fineness and pore size
The determination of geometric pore size is based on weaving parameters such as type of weave, warp and weft diameters and mesh count. The geometric pore size defines the diameter of the largest sphere passing through the weave.The underlying equations to determine the geometric pore size were developed and tested in laboratory conditions at the IMVT institute of the University of Stuttgart within the scope of the AVIF projects A224 and A251. For some weave specifications, where these equations are not valid, the pore size was determined in a dry glass bead test.
The filter fineness or pore size is an important characteristic of filter meshes. Today, this statistic is only given in terms of the absolute filter fineness. This means the diameter of the largest solid spherical particle, which can pass through the filter medium under static flow conditions. Two processes are used to establish this value, the glass bead test and the bubble point test, according to APR 901. In practice, the latter is more often used, as the glass bead test is very complex.

BOPP FI Precision woven stainless steel filter mesh
Q Single layer meshes
For monofilaments, a twilled mesh weave produces the smallest pores and a smooth mesh surface, whilst the larger material cross section gives higher levels of mesh stability. When passing through twilled mesh, the particles must negotiate five offset pore
levels. This means that oblong, thin, rod-shaped and fibrous particles are securely retained. Fine specification twilled meshes are used for fine filtration such as pressure filtration in hydraulic steering equipment and fuel filters for critical applications. Coarser specification
twilled meshes are used for pressure and vacuum filtration (disc, cell and drum filters) and as a porous medium for fluidised bed applications. These meshes are usually manufactured from stainless steel.

Q Twilled weave
These meshes have a slightly textured surface and are particularly useful for
high flow rates and low pressure loss. They are used where mechanical loading
is increased, such as for settling filters and filter candles.
Q Plain weave
7© G. BOPP + CO. AG, CH-8046 Zurich – www.bopp.ch
Betamesh is a further development from plain weave mesh. In comparison to the standard plain weave, it has a greater pore count, and the pores on the surface are smaller than the inner pores. The mesh therefore achieves higher flow rates and greater dirt removal
capabilities, and also features exceptional backwashing performance. These meshes are generally used for oil and fuel systems, subject to higher levels of contamination, and also to protect steering and fuel injection jets as well as friction bearings.
Betamesh R is a variant developed for simpler filtration tasks, which is particularly suitable for higher mechanical loadings due to the Robusta mesh design.
Q Betamesh
Thanks to higher levels of porosity, this mesh can withstand particularly high flow rates. A regular
cross section in both warp and weft directions facilitates the highest mechanical loadings. These
robust meshes are used for settling filters, filter candles, vacuum filters and well filters.
Q Robusta
BOPP FI Precision woven stainless steel filter mesh
8 © G. BOPP + CO. AG, CH-8046 Zurich – www.bopp.ch
These meshes also achieve high flow rates and can withstand high mechanical
loadings. Duplex meshes are the preferred choice for applications such as pressure
and vacuum fi l ters , as wel l as f i l ter candles .
Q Duplex
In contrast to the twilled meshes, the wires in this design of mesh are woven with a gap. This results in open apertures, which liquids can stream through. Exceptionally
low resistance and particularly effective backwashing are two particular characteristics of this mesh. Square weave meshes are used for dirt filters with low pressure differentials,
for applications such as backwashing in conjunction with support meshes.

Q Multi-layer sintered meshes (laminates)
POREMET is a plate-like filter medium consisting of five different layers of mesh. The mesh layers are put together and sintered
using both heat and pressure. The special design achieves an optimum combination of stability, filter fineness, flow rate and back-
washing properties. POREMET is used primarily for the filtration of highly viscous liquids.

Q POREMET
Our product portfolio includes a range of highly developed mesh laminates for diverse applications. On request, we can produce bespoke mesh combinations with special properties.
ABSOLTA N is a laminated sinter mesh, similar to POREMET with optimum flow
rates and backwashing capabilities.
Q ABSOLTA N
ABSOLTA D is a five layer construction with a reduced thickness of 1.7 to 1.8 mm.
ABSOLTA meshes are used in liquid and gas filtration applications.

TOPMESH 2 is a two layer combination consisting of a filter mesh and a support mesh. Sintering the two together results in
a robust filter medium for fine filtration in harsh industrial conditions.
Q TOPMESH 2
TOPMESH 3 is a stronger version, strengthened using two support mesh layers. This mesh is used
for even tougher conditions.
Q TOPMESH 3
POREFLO is a plate-like, two or three layer laminate, where offset layered filter meshes are compressed to achieve different levels of
filter fineness. The laminate is transformed into an air permeable metallic membrane, which is used in fluidisation and aeration applications
and in fluidised bed technology.

Eu: The non-dimensional Euler number describes the ratio of pressure forces to inertial forces for the different weave specifications at similar flow conditions. The higher the Euler number of a weave specification, the higher the pressure loss of this weave specification will be. The Euler number allows comparison of differing weave specifications in terms of pressure loss. The determination of geometric pore size is based on weaving parameters such as type of weave, warp and weft diameters and mesh count. The geometric pore size defines the diameter of the largest sphere passing through the weave. The underlying equations to determine the geometric pore size were developed and tested in laboratory conditions at the IMVT institute of the University of Stuttgart within the scope of the AVIF projects A224 and A251. For some weave specifications, where these equations are not valid, the pore size was determined in a dry glass bead test.

Notes:Pressure drop is calculated for gas at an inflow speed of ca 20m/min. The values are suitable for comparing the laminates.As is the effective average of the wires, which run perpendicular to the cut edge. Rp0,2 is the minimum value in trials for Poremet and Absolta and is derived for Topmesh and Poreflo.The values given in these tables are typical for sintered meshes. These properties are not guaranteed.We retain the right to make technical changes and to implement further developments.
