Leading UK engineers choose extraction by J.B.Thorne
24th April 1998

Kenard Engineering Co, the Dartford-based precision mechanical engineering company, has installed Polytex dust extraction equipment by J.B.Thorne to handle dusts in a specialised workshop cutting plastics and epoxy glass fibre materials. Previously, Thorne had also supplied a smaller K95 Polytex unit to extract dust created by a diamond-blade circular saw cutting sheets of similar materials.

In the latest installation Kenard, an approved supplier to many leading industrial groups with global markets, needed extraction for two CNC milling machines producing components and insulating boards for the electronic and telecommunications industries. The equipment chosen was a Polytex L35 from Thorne, who also designed and installed all ducting for the project.

"The equipment has proved very satisfactory," commented Kenard sales manager Graham Oakley, "and we are very impressed with the levels of extraction efficiency being achieved."

Polytex units work by collecting dust at source, drawing it through ducting by a powerful fan and trapping it in the filter bag system. Waste dust is collected in bags at the base of the unit, for sealing and disposal. In a multiple installation covering several work stations, units may be switched on individually, bringing further energy-efficiency.

Because. of their relatively small footprint, Polytex units of various sizes and extraction capacities may be sited in even restricted areas, both inside and outside. And with the inclusion of a top-mounted high-efficiency particle arrestor (HEPA), extraction efficiency of 99.997 per cent is possible, allowing cleaned air to be returned to the working area.
