Using a conventional air compressor. Air is driven across the mouth of a small outlet under pressure to draw liquid paint out of the container and produce an air-paint mist from the nozzle of the spray gun.
Airless spray painting. The paint container is pressurized pushing the paint to the nozzle where it is atomized by the spray gun.
An electrostatic spray painting. An electric pump drives the electrostatically charged liquid paint out of the nozzle which is then applied to the object which is earthed.
Powder coating is a process by which electrostatically charged powder is applied onto an earthed object. Spray painting and powder coating are carried out in a variety of industries. For example, items that are commonly spraypainted include motor vehicles, buildings, furniture, white goods, boats, ships, aircraft and machinery.
