Abstract
A compact vacuum container includes a tangential air inlet at the upper portion, a closed top and a central outlet at the bottom having an improved air separation and dirt collection container is provided. A hollow central column with a skirt formed with a downwardly extending flange having an outer diameter is less than the inner diameter of the container, extends from the closed to the bottom outlet opening the upper position above the skirt is open and the lower portion of the column is solid. Dirt particles that separate from the air flow above the skirt drop to the lower portion below the skirt. Clean air then exits an open upper portion of the column to the suction source below the container. The air exiting the bottom of the column may pass through an radially pleated filter before being drawn into the vacuum source.
