Extraction arm and hood.

An extraction arm can be bent into position over the work, with a flow regulator for the suction. At the same airflow, a larger hood gives slower air in front of it, so a larger hood needs more air.

The arm

Bring the opening to the source.

An articulated arm can be bent into any position you need to extract the dust.

The arm comes with a flow regulator to adjust the suction. Depureco also offers an ATEX articulated arm in stainless steel for combustible dust.

The hood

A larger hood needs more air.

At the same airflow, a larger opening gives slower air in front of it.

A flange around the opening helps: it lowers the airflow needed for the same capture velocity.
