ABSTRACT:
A tent-like portable blasting room enclosure is provided with a central entry opening in the roof. Air is circulated through the blasting room enclosure and exits through spaced parallel air return ducts extending along the lower edges of the opposite side walls of the blast room enclosure through a closed loop abrasive conveying air stream. Inlet air diffusers are provided in the upper portion of the blasting room enclosure for uniformly distributing the air introduced into the blast room in a downward direction without creating turbulence in the blast room. The parallel air return ducts extend outwardly beyond the blasting room enclosure and define a second floor area adjacent the first floor area beneath the blasting room enclosure. The blasting room enclosure is mounted on rollers and a track extends parallel with the air return ducts to permit the blasting room enclosure to be moved between the first and second floor areas so that parts to be cleaned can be removed and replaced in the open floor area while sandblasting is taking place in the other adjacent floor area.
