A spray gun combines the coating (paint) and compressed air from a separate air compressor in order to atomize the coating and direct it to the target surface. The coating is held either in a small bottle or container attached to the spray gun or in a separate pressurized container attached to the spray gun with a hose.
HVLP (High Volume Low Pressure)
This is similar to a conventional spray gun using a compressor or HVLP turbine to supply the air, but the spray gun itself requires a lower pressure (LP). A higher volume (HV) of paint is therefore applied at a lower air pressure. This results in more paint landing on the target surface instead of staying airborne. A regulator is often required so that the air pressure from a conventional compressor can be lowered for the HVLP spray gun.
HVLP spray systems are used in the automotive, marine, architectural coating, furniture finishing, and cosmetic industries.
