Air filtration assembly with positioning aid

An optical positioning aid assembly to guide a user relative to positioning an intake of the air filtration assembly relative to a work tool to optimize efficiency of the air filtration assembly for filtering gas or particles generated responsive to operation of the work tool, the optical positioning aid assembly comprising:

• a first light disposed at the intake;
• a second light disposed at the intake and offset from the first light;
• a third light disposed at the intake offset from the first and second lights and forming a triangle with the first and second lights;
• and
• a fourth light disposed at the intake,
• wherein each of the first, second, third and fourth lights are aimed at a work surface on which the work tool is disposed.

A work system comprising:

• a work tool;
• a workstation at which the work tool performs a work task;
• and
• an air filtration assembly for filtering gas or particles generated responsive to operation of the work tool, the air filtration assembly comprising:
• an intake repositionable relative to the work tool;
• a housing operably coupled to the intake, the housing comprising a filter, a motor and processing circuitry;
• and
• an exhaust operably coupled to the housing,
• wherein the processing circuitry is configured to control operation of the air filtration assembly,
• wherein air enters the air filtration assembly at the intake responsive to operation of the motor, before passing through the filter and exiting out the exhaust, and
• wherein the intake comprises an optical positioning aid assembly to guide a user relative to positioning the intake relative to the work tool to optimize efficiency of the air filtration assembly.
