 Air Compressors – How Do They Work?
Compressed air is required to operate an airbrush. In the
case of an air compressor, air is drawn into the equipment and compressed
with a piston. This compressed air is usually stored in a tank that has an
air regulator attached, the purpose of which is to stop air from being
emitted when not required. To allow air, the regulator is adjusted to a
particular poundage. The air enters the hose of the airbrush (or spray
gun); then when the airbrush trigger is activated, the air causes a vacuum
in the brush that in turn draws paint from the paint reservoir into the
stream of air. These mix inside the tip of the airbrush and then exit in a
fine spray. Different types of paints and different applications, e.g.,
illustration or kustom automotive painting, require different air pressures,
which are adjusted at the regulator.
When air is compressed, heat is generated, causing
condensation. Little droplets of water collect in the air storage tank or
the airbrush hose. A moisture trap is required to prevent this water from
being sprayed or mixing with the paint. For compressors that contain oil
for operation, an oil trap is required to prevent the oil in the crankcase
of the compressor from mixing with the sprayed air. See your retailer when
choosing your compressor/accessories and visit
