  • Patent number: 5291628
    Abstract: A high velocity air and stationary disturber cleaner for cleaning surfaces by drawing air under flexible film seals. A vacuum enclosed in a housing provides the suction force to draw the air under the seal, tangent to the surface to be cleaned, thus removing adhered particles. Disturbers are placed on the surface of the seals in contact with the surface to be cleaned to loosen particles to be removed. The brush density, the fiber length and a plastic film incorporated into the brush design are all ways to limit the amount of air flow through the bulk of the brushes for better cleaning efficiency.
