The air speed needed where the dust is released to pull it into the opening. The capture zone is the area in front of the opening where the air is fast enough. Recommended values run from 0.38 to 10.2 m/s, depending on how the dust is released.
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.
CP hoses for extraction arms and dust collectors with a fan. AIRDUC hoses for industrial vacuum cleaners. Find your machine’s maximum vacuum on its product page or rating plate. If it is not stated, ask us.
