Paint sprayers usually depend on air as it is the only way to deliver pressure for spraying. But now it is possible to spray paint without using air. These sprays utilize pumps that can push up the paint to the hose and the paint comes out through a gun without air pressure. An airless paint sprayer functions by pumping out paint at an excessive pressure, which is 3000 psi. The paint comes out via a hose and it comes out through a very small hole via spray gun tip. The tip is specially designed to break the paint in an even manner and the spray comes out in fan-shaped and in form of tiny droplets.
Functioning of airless spray painting
Surface tension and viscosity binds the liquid together and atomization taking place scatters these to develop droplets mist instead of fluid mass. In these sprayers, there is a lot of energy produced due to high pressure injected in the paint. The amount of liquid that would come out is decided by the size of the hole in the spray nozzle. In the market, there are different ranges of tips available to manage atomization that causes varied spraying sizes and patterns. The three components of airless sprayers are the spraying gun tips, pumps, and motors.
Majority sprayer tips can be interchanged mainly for flexibility and you must choose the tip size accordingly based on the capacity of the spraying unit, the type of paint sprayed and the amount of pressure needed for atomization. These tips come with numbering systems, the smaller numbers are best for spraying stains and lacquers, a bit larger ones for enamels, even larger for indoor latex paints and oil-based ones. The largest tips are for thick coatings like exterior latex coats.
