ABSTRACT:
A cabinet device is provided for use in combination with an abrasive blasting system. The inner chamber of the cabinet device is maintained at a pressure of less than ambient air pressure during an abrading operation by applying a source of vacuum to an exhaust outlet in the bottom of the cabinet below the article being abraded which is supported on a rack in the chamber. A blasting gun in the chamber is manipulated from outside the cabinet by an operator. An inlet for ambient air is located in the cabinet above the article on the rack and, during an abrading operation, establishes a continuous current of air downwardly toward the cabinet exhaust outlet to clear the space in the cabinet above the rack of view-obscuring debris and dust caused by the blasting operation. An improved sealing device between the cabinet cover and the peripheral sidewall of the cabinet housing is also provided.
