An electrostatic powder coating system that comprises a booth, the lower part of which is designed in the shape of a V, and a collecting channel (13), connected to a suction device (2) underneath, the booth having two ends, each of which has a pass-through opening for the workpieces. The collecting channel (13) is covered by floor plates (17), which can be walked upon or swung up into a vertical position, and which are provided with exhaust slots (18, 19, 20) extending in the longitudinal and transverse directions, it being advantageous for the total area of the slots be a function of the discharge of exhaust air and the velocity of the exhaust air. The floor plates, which can be swung upward, improve the ability of the booth to be walked on and thus increase the ease with which the system can be serviced and operated. As a result of the way in which the exhaust slots are arranged, the powder residues can be extracted more homogeneously and uniformly and thus in optimum fashion over the entire length of the booth.
