ABSTRACT:
Process and apparatus for cleaning workpieces by means of at least one jet of compressed air, in which the workpiece is brought into a cleaning station, a high-pressure stream of air is generated by means of a high-pressure air pump, this stream of air is supplied to a blast nozzle directed onto the workpiece and waste air fed back to the suction side of the pump via a filter, wherein to avoid any escape of waste air laden with impurities into the surroundings the workpiece is cleaned in a chamber closed so as to be at least essentially air-tight apart from an air inlet in the form of the blast nozzle as well as a waste air outlet and the air is circulated in a closed air circulation system including the chamber and wherein solid particles are mechanically filtered out of the stream of air upstream of the pump.
