HVLP uses a high volume of air (typically between 15-22 CFM) delivered at low pressure (10 psi or less) to atomize paint into a soft, low-velocity spray pattern. As a result, far less material is lost in overspray, bounceback than with conventional air spray. This is why HVLP delivers a dramatically higher transfer efficiency (the amount of material that is actually applied to the part) than higher pressure spray systems.
The HVLP spray gun resembles a standard spray gun in shape and operation.HVLP is growing in popularity and it has also been judged environmentally acceptable due to its high transfer efficiency. HVLP can be used with low to-medium solid materials, including two-component paints, urethanes, acrylics, epoxies, enamels, lacquers, stains, primers, etc. More recently developed HVLP air caps can also satisfactorily atomize even high solid coatings.
