An alternative paint feed that has gained popularity in recent years, is supply from a gravity cup above the HVLP spray gun . The choice between syphon/suction cup or a gravity cup is a question of preference by the sprayer. Both cups tend to get in the way of the sprayer’s view and both give a different balance to the gun. Feeding the spray gun with paint under pressure by hose from a remote tank avoids the work visibility problem, but is only worthwhile for the application of larger volumes of paint.

Since a significant amount of paint is lost in overspray, even with the more efficient HVLP spray guns, all air spraying must be done inside a spray booth. This is a legal requirement and the booth must conform to a national standard which will soon be the same as the new European standard. Please see our section on spraybooths. The spraybooth not only protects others from paint overspray and solvent vapours, but keeps dust away from the work being sprayed by filtering the incoming air.

The air supplied to the spraygun should be water and dust free as both will spoil the finish.pychvjht It is normal practice to install particle filters in the air supply, usually upstream (the compressor side) of the air pressure regulator. These air filters may include a water trap that is drained by opening a tap from time to time, or automatic which is operated by a float valve. Whilst simple water traps may remove the bulk of the water, the air will still retain a certain amount of humidity and this can be removed by either a condensing dryer that cools the air down below the dewpoint, or by a chemical desiccant dryer. All bodyshop paint spraying must be done in a spraybooth that meets national standards; please see the section about spraying in a spray booth.
