An airborne component extraction system includes a source of a positive pressure air stream and a source of a negative pressure air stream. The air streams are directed through conduits to a hood that distributes the positive pressure air stream into a work area, and that draws the negative pressure air stream from the work area to remove airborne components within the work area. Aspects of the hood offer greatly enhanced performance in creating a controlled region for component removal and for drawing and removing the components for the work area.

Various embodiments of the present disclosure provide a curtain wall panel bracket leveling system that facilitates leveling a panel bracket mounted to a fixture (such as an embedment or an anchor array) cast in a concrete slab.

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.
