A collection compartment is disposed below the working surface and the air inlet opening therethrough with a rear portion of the collection compartment being disposed within the interior of the cabinet. A filter is disposed within the interior of the cabinet between the collection compartment and the fan. The fan causes the air including the particles produced at the working surface to be drawn downwardly through the air inlet opening into the collection compartment, upwardly from the rear portion of the collection compartment, and through the filter. A substantial portion of the particles remain in the collection compartment and a remaining portion of the particles are collected on the filter. The collecting compartment is accessible for selectively removing the substantial portion of the particles from the collecting compartment.
