Abstract
An electrostatic powder coating gun for dispersing aggregate powder onto substrates. The gun includes swirling air passage outlets to form a vortex of air inside the spray gun tip to reduce powder adhesion and assist in pulverizing the powder material. The coating gun employs a powder supply unit having a fluidized bed that includes temperature and humidity controls to adjust the temperature and humidity of the compressed air supplied to the spray gun and a mixer to agitate the powder in the container.
