HVLP (High Volume Low Pressure) air turbine sprayers for paint and varnish are simple and effective tools for achieving uniform application of paint or varnish. They consist of three main elements: the turbine, the hose, and the spray gun.
The turbine is the heart of the HVLP system and generates the air needed to atomize the paint. The number of stages of the turbine determines the power of the unit. The more stages, the higher the air pressure and flow rate, allowing for better atomization of the paint.
The hose connects the turbine to the spray gun and carries the compressed air generated by the turbine. However, the length and quality of the hose can affect the performance of the system. A hose that is too long or of poor quality can result in a loss of pressure and reduced air flow.
The spray gun is the tool that applies the paint to the surface to be painted. It is equipped with a spray orifice and an adjustable nozzle to control the size and shape of the paint spray. The quality of the spray gun is essential for achieving a smooth and uniform finish.
Single and two-stage units are ideal for thin finishes and are generally more affordable and popular on the market. A three-stage turbine can handle most water-based stains, varnishes, and finishes, although latex will need to be thinned for optimal application.
HVLP systems with multiple 4 and 5-stage turbines are better suited for more demanding spray work, including the application of thicker paints or the use of high viscosity materials.
