Abstract: Apparatus for applying of coating material on target objects (11), consisting of at least one painting cabin (10). A conveyor is passing the objects (11) step wise through the cabin (10) and through an adjacent evaporation cabin (30). The painting cabin (10) is divided into two adjacent zones consecutive in the direction of the conveyor movement through which zones air currents (V4a, V4b) are passed one after the other. Air currents (V2, V5) being drawn from the zones are washed and cleaned in related color particle separator devices (12a, 12b) and heated with heaters (22,24) above the respective due points. The solvent loaded discharge air currents (V10, V11) are fed from the evaporation cabin (30) into a combustion plant.The air currents are adjusted in such manner that in the entrance area underpressure exists and a fresh air current (V1) is passing into the cabin (10). A security control and maintainance equipment is described.
