What is an HVLP spray gun?
A standard spray gun—usually connected to a compressor—aggressively propels finish onto your project; so aggressively, in fact, that as little as 25 percent of the finish may actual wind up on your project. HVLP spray guns dispense finishes at high volume, low pressure (HVLP) which results in less overspray and, when used properly, a finer finish. Cabinetmakers and furniture builders love them.
There are two kinds of HVLP spray gun systems. A dedicated system employs a turbine to atomize the finish. These systems are small and portable, but can be quite expensive. A conversion system converts the high-pressure air from a compressor to a lower pressure to create a lower volume, more controlled spray.
