The built-in high voltage static generator applies very light spraying gun (only 450g) with the electrical circuit imported from Germany and full stainless steel powder supply bucket. The built-in high voltage module is robust and removable, the central gas design is unique and the handy trolley can change spraying position rapidly. The high voltage module closely link spraying nozzle so that the high voltage consumption is lower, the discharging effect can be intensified, power loading rate can be increased, corners can be coated by spraying and circular atomization effect is good. The powder delivery is uniform and stable. The high voltage static generation environment is very bad and the generator is used thousands of times every day. In response to this, the company applies anti-dust switch to fully split the electrical circuit and gas circuit. The static generation unit is fully enclosed in a box where no dust can enter, therefore, the chances of damaged dramatically decreased.
