CA 2125796

A high speed propane power buffer is provided with a dust evacuation system. A peripheral skirt is telescopically depended from a hood overlying the high speed rotating buffer pad. This skirt, at the extremity adjacent the surface to be polished, is supplied with angularly inclined grooves sloped away from the radial disposition with respect to the buffer. These angularly inclined grooves slope from the outside of the skirt to the inside of the skirt in the direction of buffer disc rotation at the disc periphery and are maintained by the telescoping skirt immediately adjacent the surface being polished. Entrained air is drawn at the surface being polished in the direction of buffer disc rotation from the outside of the skirt to the inside of the skirt through the slanting louvers establishing a buffer dust confining boundary at the depending peripheral skirt immediately adjacent the floor.
