This is a blow and suction dust removal system for watchmakers.

It comes with a blue blow/suction pen and a gray dual-tube setup.

No screws are needed to mount it.

It is fixed to the workbench by tightening a round clamp that holds the table from the top and bottom.

You only need one air compressor to use both the blowing and suction functions.

The suction is created by a negative pressure generator, which turns the air from the compressor into suction through a foot pedal.
