The quality of a paint job in refinishing work is affected by the quality of the compressed air that is used.
If there is an inadequate quantity of compressed it can negatively affect texture (cause orange peeling or spotting ) and even poor color matching and streaks. All this slows production and creates an unacceptable finish.
Moisture in the compressed air causes poor gloss, poor adhesion, un-cured finish, poor durability and fast film setting. This makes it hard to sand and hard to buff and again an unacceptable finish.
Particles in the compressed air will also negatively affect the finish requiring repainting, color sanding and buffing.
An inadequate quantity of compressed air can be caused by leaks and pressure drop. Not only do leaks cause a tremendous amount of unnecessary cost I can be up to 30% of the compressed air wasted in a system. Leak detectors like one supplied by Nex Flow can be used o easily identify leaks which can then be fixed. A second thing that could be causing an inadequate supply is pressure drop. Fittings, connections should all be checked to assure no unnecessary line restrictions and definitely check water and particulate removing filters in line. If not maintained properly, they can build up a large pressure drop chocking air supply.
And of course, proper filtration to remove moisture and particulate is important and mentioned above should be maintained. One filter on the market called the Expel filter removes 99.9999% of moisture form the system and guarantees particulate removal to 1 micron (ISO 12500 tested and approved). It is ideal for paint systems in that the pressure drop across this filter is small and does not build up. Nex Flow also makes this unique filter available.
