Knitted wire mesh filter element Begg Cousland

‘Becoil’ knitted mesh demisters.

In many industrial processes it is necessary to remove mist or spray droplets from air or gas streams in order to purify the gas, remove liquid which would contaminate the subsequent process, damage downstream equipment, constitute an undesirable atmospheric emission, or to recover a useful liquid product of the process.

'Becoil' Demisting Units are separators of the impingement type consisting of multiple layers of fabric knitted from metal or plastic monofilaments, crimped and than assembled so that the crimps cross in successive layers. Pads fabricated in this way have a very uniform voidage with an extremely high ratio of filament surface area per unit volume of pad.

Collected liquid in the mesh forms discrete droplets on the filaments which fall off as the force of gravity overcomes the combined forces of the rising gas and surface tension, which tend to hold the droplets to the filament.

'Becoil' Demisting Units have been specially designed to achieve highly efficiency removal - up to 100% on entrained droplets above 5 microns in size, while generating low pressure losses and are virtually maintenance free.
