Abstract
A extraction system is designed for metal working and other applications. The system may comprise a cart-type base or may be incorporated into a fixed or semi-fixed installation. A blower delivers a positive pressure airflow to a hood that creates an air region by directing the air through an annular space between inner and outer shrouds, impacting the air against a single generally perpendicular flange. Return air from the operation may be mixed with fresh air, both of which may be filtered, to supply the positive pressure air. Both air streams to and from the hood may be adjusted to optimize operation. Adjustments may be made at the base unit or remotely.
