The heart of an airless spray machine is its hydraulic pump. This pump pressurizes the paint, typically to very high pressures, which allows for efficient atomization and delivery. Advanced airless spray machines can generate extremely high pressure, often exceeding 3,000 psi (pounds per square inch). This high pressure enables the machine to produce a fine, consistent spray pattern even when using thick paints or coatings. The spray gun is equipped with a precision nozzle that controls the flow of paint and the width of the spray pattern. These nozzles come in various sizes to accommodate different types of coatings and application requirements.
