Turbine systems, on the other hand, provide a complete, self-contained, portable package that includes the gun, air supply (the turbine unit), and hose. These three parts of the system work in concert to produce a smooth, level film on your project. Many tradespeople in the woodworking industry make use of HVLP Turbine Systems to finish their product. I've used the system for mobile auto paint touch up nearly every day for over three months. Like conventional spray guns, conversion guns atomize finish with air supplied by a compressor, and that air must be filtered of both water and oil to avoid contaminating the finish.
To best atomize a finish, three spray-gun adjustments must be balanced: fluid flow (the amount of finish leaving the gun), airflow (the amount of air exiting the spray cap), and fan width (how broad or narrow a pattern the gun can spray).

An HVLP turbine is a series of fans, called stages, that move a lot of air at low pressure, and more stages equal greater air output (rated in cubic feet per minute, or CFM), which means better atomization. Routing air from the turbine to the gun, the hose is the final big piece of the HVLP puzzle, and a good hose has durability, flexibility, and low weight. I have since done a display case for a Hockey Jersey & I am currently working on spraying trim for the house---I couldn't be happier with the results. As much as 80 percent of the finish that leaves a conventional spray gun bounces back off your workpiece, and winds up on every exposed surface, including the shop floor, walls, shelves, and tools.
A powerful turbine can't compensate for a poorly performing gun, nor can the best gun effectively atomize finish with an anemic turbine, but a restrictive or easily crushed hose can render the whole system ineffective.
A knob on the gun controls fluid flow; to control airflow, most HVLP turbine systems costing more than $600 use a valve either in the air line or on the gun (we like the air control at the gun end of the hose, which saves walking back to the turbine).

A too-stiff hose tends to steer the gun during spraying; a more flexible hose may not return to its original shape, restricting airflow.
And, as your spraying skills improve, you can use techniques like toning and shading (adding color between finish coats) that bring depth and sophistication to your finishes. HVLP sprayers, on the other hand, use a large volume of air at low pressure to break up, or atomize, the stream of finish leaving the nozzle into a fine mist.
