On drilling boreholes by means of rotary and/or percussion drilling water is preferably used to flush out the cuttings. On various applications this process has to be carried out with compressed air – so called ‘dry drilling’.
In order that the cuttings create no emissions they must be collected by extraction and separated. For this purpose CFT GmbH has developed an extreme high-performance dry cuttings extraction system which is patented and stands out due to the application of a high-effective rotary piston fan for generation of underpressure as well as a compact element filter suitable for
the achievement of the MAC provisions permitted underground. While applying a CFT dry cuttings extraction system we guarantee you an almost complete collection of cuttings. There are extremely strict statutory provisions for underground applications. The value for residual dust of the filter system is still lower as per specifications for legal clean air recirculation.
