LE-DK series automatic spraying chamber is composed of chamber, delivery, exhaust system, disc electrostatic spraying gun, high voltage electrostatic generator, paint supply device, frequency conversion elevator, fire and explosion protection device, control device and indoor lighting. In painting operation, the coating is thrown out through a charged disc, which runs at high speed. At this time, the coating has static electricity and repels each other through charged particles, so that the coating can be further atomized to form more fine particles, and form a surrounded electrostatic effect, thus achieving smooth and delicate spraying effect. Therefore, in the high-quality coating effect of products, it also greatly reduces the paint loss rate of spraying operation, and has the advantage of complete practice electrostatic painting.
