Device for automatically blowing the adhering water off after passing through the pretreatment plant. The rotary blow-off zone is a device for blowing the adhesive water off workpieces that have been washed for the purposes of painting. It consists of a closed stainless steel sheet metal housing with forced ventilation and is employed immediately after the washing installation. In order to achieve more effective drying in the case of fissured surfaces, the blower nozzles are arranged on a rotary axis. The adhering water is blown off by the parts by air blown at high speed through the rotary blower nozzles. The effect of this is that no water droplets remain on the workpiece that could lead to slight marks in the paint film. Due to the varying blowing direction, the water is also blown out of problem zones and scooped parts in most cases. In order to be able to optimise the direction of the blower nozzle air jets, the nozzles have adjustable nozzle heads. The water that is blown off runs back into the pretreatment plant. The blowing air is extracted from the blowing tunnel via a return air duct with adjustable suction apertures.

Newly designed slotted jets arranged throughout the entire operating width guarantee constant flow conditions in the drying compartment. Depending on the coating material, the air is heated via hot water, thermal oil or steam in special heat exchangers. Particularly intensive drying is achieved through the high air speed in the jet channel.

The AQUA BLAST wet blasting cabinet is a combination system for degreasing and simultaneous gentle beams of various workpieces. The water - jet mixture is housed in the cabin swamp. This abrasive mixture is sucked in via a novel centrifugal pump of wear-resistant polyurethane. At the jet of compressed air is additionally adjustable added so as to achieve an optimum surface finish. After loading of the workpiece, the blasting medium mixture flows back into the cabin sump and is thus an abrasive circuit ensured. Battered fine abrasive is suspended from the cab sump and fed to a band filter on the cabin back.
