Extraction points can cover a number of areas including: -

• Above specific working areas
• At material loading points / bays
• Within workshops or processing stations

Systems usually incorporate wet or dry filters to regulate emissions to atmosphere within legislative requirements.

Fire or explosion relief is built in as required.

One specific example is on a skull lancing plant where the fume and dust created from the oxygen cutting of the bottom skulls used in steel production is extracted from within a mobile hood before being passed firstly through a dust and spark arrester and onto a cartridge filter.

The total system ensures the protection of the operator and clean air emissions to atmosphere.
