BOPP FILTER MESHES
BOPP offers a range of different mesh styles, dependent upon requirements and service conditions.
Twilled mesh gives the smallest apertures for monofilaments as well as a smooth mesh surface, whilst the larger material diameter gives higher levels of mesh stability. To pass through the mesh, particles must negotiate five offset pore levels. This means that even elongated, thin, rod-shaped and filamentary particles are reliably retained.
These meshes are used at fine specifications for fine filtration such as pressure filters in hydraulic steering equipment and fuel filters in critical applications. Coarser specification twilled meshes are used in pressure and vacuum filtration (disks, battery and drum filters) and as a porous medium for fluidised bed applications.
These meshes feature a lightly textured surface and are characterised by extremely high flow rates and minimal loss of pressure.
They are used for alluvial filters and filter candles with increased mechanical loadings.
This stainless steel filter mesh offers high flow rates and advanced dirt removal capabilities.
These meshes are used for oil and fuel systems, mainly where advanced dirt removal capabilities and high flow rates are required, for the protection of steering and injection jets as well as friction bearings.
These meshes are characterised by high flow rates due to increased porosity. They can be compared with smooth weaves, but due to consistent material diameters in both warp and weft directions they are suitable for applications with high mechanical loading.
Typical applications include alluvial filters, filter candles, vacuum filters and tube filters.
These meshes are characterised by high flow rates. They are suitable for increased mechanical loadings and have a lightly textured mesh surface.
Duplex meshes are commonly used in applications such as pressure and vacuum filtration as well as filter candles.
Square weave mesh
In contrast to twilled meshes, the wires in these meshes are woven offset. This results in an open mesh, through which the flow passes in a linear manner. This mesh style is characterised by exceptionally low flow resistance and particularly good backwashing and cleaning properties.
Square weave meshes are used in protective filtration with low differential pressures and for applications including backwashing filters when used with a support mesh.
