Paint has to be drawn from below the gun or is fed from the top down into the nozzle for achieving sufficient atomization. Greater air pressure in the Sata siphon-feed guns is the main restriction in using Sata HVLP systems. It is difficult to keep air pressure low and adequate vacuum. Lower air pressure is achieved by pressurizing the cup for all those users who prefer Sata feed spray guns. The fluid is forced to the feed tube by the siphon process. The pressurized cup is identified by air presence from the air supply of the cup.
