Airless sprayers are high efficient machines for quick painting large areas with maximum coverage. Unlike conventional methods - gun and compressed air or brush / roller paint application, airless sprayer machines deliver extremely high performance when applied paint only with one layer. They are widely used for the applying of various types of water-soluble paints such as latex, lacquers, etc. on smooth and structured surfaces. Airless painting machines are used for paint application on walls, facades, metal structures, halls, roofs and many other. Their main advantage is high coverage and uniform application! Тhis type of spray technology do not use compressed air, so the cloud of paint remains as thick as possible. Short description of airless painting process - the sucked paint is pushed through a piston pump to a high pressure, via a hose, is fed to the paint gun. The airless sprayer gun has a nozzle with a small cross section which results in a significant increase in the spray jet velocity. Once sprayed through the nozzle it is pulverized as a result of friction with atmospheric air.
