Spray booth and method of operating same.

摘要

A spray booth (10) is provided with an air cleaning system to remove airborne particles for use in heavy production applications where large amounts of paint are sprayed and in which large quantities of airborne particles are collected without a substantial reduction in air flow through the booth as would fall below desired minimum standard of air flow through the booth. Air flows through an open front face (14) of the spray booth and across the piece (11) being sprayed to a first water cascade means (20) which has vertical water covered surfaces (37, 38) offset in the fore and aft direction to trap paint particles and which define vertical extending slots (34) through which the air may pass. The air is deflected downwardly from the first water means across the top surface of a water reservoir (75) at the bottom of a spray booth at which surface further paint particles are trapped. The air then directed upwardly through a downwardly directed water spray wash (22) to trap more airborne paint particles. The water particles are removed from the air prior to its discharge from the spray booth.
