Abstract: An extraction system is designed for metal working and other applications. The system may comprise a blower that delivers a positive pressure airflow to a hood that creates an air region for removal of airborne components from a work area. Return air is filtered in a filter region, and debris removed may be separated by a baffle in the filter region to limit re-uptake of the debris by the blower during operation of the system.

Abstract: 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.

Abstract: An airborne component extraction system comprises a source of a positive pressure air stream and a source of a negative pressure air stream. Conduits allow the positive pressure air stream to be channeled to a work area, and the negative pressure air stream to be drawn from the work area to pull airborne components away from the work area. A manifold receives the conduits and aids in directing both air streams between the sources and the conduits. The manifold may support the conduits in the form of an arm that can be rotated while directing the air streams.

Abstract: An airborne component extractor provides a positive pressure air stream to a work area and draws a negative pressure air stream from the work area. Conduits conduct both air streams. A movable cart-type base unit or a permanent installation may provide for the air streams. Sizes and operational parameters are selected to provide good component removal, reduce head losses, and reduce power requirements.

Abstract: A component extraction system utilized a base unit that produces a positive pressure air stream and that draws a negative pressure air stream into the base unit. To enhance performance, and reduce head requirements and power consumption, a number of bends in the flow paths is minimized in the base unit.

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.

Abstract: An extraction system is designed for metal working and other applications. The system may include a blower that delivers a positive pressure airflow to a hood that creates an air region for removal of airborne components from a work area. The blower is driven by a three-phase motor in a portable base unit that may be plugged into a source of three-phase power. A rotational direction reversing switch is provided between the motor and a three-phase plug to permit reversal of the rotational direction of the motor when the motor is determined not to rotation in the intended direction when the plug is connected to a receptacle. The switch may be manual or automatic.
