5. Compatible Portable Extraction
This air tool kit has been specifically designed to be used with a compatible portable extraction
unit. The combination of a lightweight Dynabrade air motor with a bespoke vacuum shroud and
bespoke cutters requires very specific extraction.
Advice for Dust Free Operations
This advice applies specifically to the use of this air tool kit.
We recommend the use of extraction that auto-starts with the air motor operation.
We recommend the use of extraction with a ‘low airflow alarm’.
Operational conditions:
For routing bits, set the air tool speed to 12,000-15,000rpm (approx. half speed)
For surface planers, set the air tool speed to the full 20,000rpm
Extractor requirements = 5m3/hr at 5,000Pa
For our portable dust extraction unit DMP0120, use:
Hose size setting ‘16’
Variable airflow at the minimum
The second cleaning hose and brush must also be connected and open to allow the
airflow to be reduced accordingly.
For our portable dust extraction unit DMP0123:
Set the combined air pressure to for the extractor and air tool to 6 Bar / 80psig
The second cleaning hose and brush must also be connected and open to allow the
airflow to be reduced accordingly.
During extensive trials, no airborne dust was present with the materials listed below. In some
cases, small localised debris between 1-4mm maybe projected locally, which falls but does not
become airborne. The presence of debris varies dependant upon the quality of the laminate
and the feed rate used. We have much more information available, please contact us to
discuss your requirements.
