Begg Cousland Envirotec have been using worldwide & exclusively distributing in certain countries Benvitec Environment’s BlueFil® meshes, mesh pads & demisters, along with our traditional knitted wire mesh types. BlueFil® is a reliable material and technology in liquid separation processes, air pollution control or to remove particulates from a gas flow.
We use these ‘pyramid-structured’ meshes, with their 3D interlocked monofilament wires in duties where there is a need for a thermoplastic material with a meshpad strength sufficient to resist the operational duty of gasflow, liquid load and, often, soluble or insoluble particulates. The mesh has a very open structure which allows it to handle particulates for a long time before blockage would occur, and which is then quite easy to wash without damage, and re-use.
When used not as a demister mesh, but as a gas scrubber media, the open structure and mesh geometry facilitate the scrubbing process with irrigation sprays co-current or counter-current. Vertically or horizontally installed, the liquid and captured solids will easily flow off the monofilament wires and maintain the benefits of the low pressure loss that BlueFil® offers in all cases.
Examples of our use of BlueFil® are :
BlueFil® mesh is cut with lasers to ensure a dust-free material with clean edges.
The meshes can be supplied with support grids, frames or cassette frames in suitable materials such as PP, FRP, PFA, Stainless Steel, 904L & Tantalum.
In the tables below you will find technical data about the mesh styles offered, and the physical data of these products, all of which are thermoplastic materials. In the Standard Solutions table you will see information about the most common mesh combinations and their typical efficiencies.

BlueFil® demisters consist of one or more precisely structured media layers. The use of one or multiple layers and the right choice of filament diameters in these layers allow you to achieve the highest efficiency at the lowest pressure drop (Dp) for your specific requirements. BlueFil® demisters are characterized by a large contact surface area and an unbeatable void space up to 97%!
