Extractor with segmented positive pressure airflow system

An extractor system comprising:

• a negative pressure conduit configured to convey a negative pressure gas stream from a work area, wherein a first end of the negative pressure conduit is coupled to a negative pressure gas stream source, such that the negative pressure gas stream is conveyed from the work area through a second end of the negative pressure conduit and toward the first end of the negative pressure conduit;
• a positive pressure system, comprising a plurality of positive pressure assemblies disposed at different positions about a circumference of the negative pressure conduit at the second end, each positive pressure assembly comprising:
• a positive pressure gas stream manifold coupled to a dedicated end cap;
• a dedicated motor disposed within the positive pressure gas stream manifold;
• and
• a dedicated fan coupled to the motor, wherein the fan is configured to draw ambient air into the end cap, generate a positive pressure gas stream from the air, and direct the positive pressure gas stream through the positive pressure gas stream manifold;
• a handle attached to the negative pressure conduit;
• and
• an operator interface, on the handle, configured to allow a user to individually control the plurality of motors, wherein each motor of the plurality of motors drives at least one fan of the plurality of fans.

A method comprising:

• directing a negative pressure gas stream through a negative pressure conduit;
• directing a plurality of positive pressure gas streams through a plurality of positive pressure gas stream manifolds disposed at different positions about a circumference of the negative pressure conduit, wherein each positive pressure gas stream manifold comprises a dedicated motor and a dedicated fan coupled to the motor, wherein the fan is configured to draw ambient air through an intake at a dedicated end cap to generate a positive pressure gas stream from the air, and direct the positive pressure gas stream through the positive pressure gas stream manifold, wherein the plurality of positive pressure gas stream manifolds are connected to a positive pressure head connected to a second end of the negative pressure conduit;
• simultaneously with the directing of the plurality of positive pressure gas streams, limiting the positive pressure gas stream through at least one of the plurality of positive pressure gas stream manifolds;
• and
• individually controlling the motor in each positive pressure gas stream manifold via an operator interface on a handle attached to the negative pressure conduit.
