The atomizing air is controlled by the second ATOM valve 13. The fluid needle control knob is located at the rear of the gun body. However, like a Pressure fed hand gun the main fluid control should be carried out by the fluid Pressure and the Fluid Tip diameter. 3. What is the difference? Conventional, HVLP and Trans-Tech are all members of the Air Atomisation family, but each has slightly different operating parameters. Here is a very quick explanation of the differences. Conventional Air Atomising The most established method of air atomizing, used on spray guns for decades. It uses high velocity air jets to produce a very high atomization power. However this speed results in a low efficiency due to the considerable ‘bounce-back’ and ‘spray-fog’ caused. Air Pressure inside the Air Cap during use is typically 2 to 4 bar (30 to 60 psi) with an air volume consumption of 170 to 700 l/min (6 to 25 cfm). High Volume Low Pressure (HVLP) Although not a new, this method first became important in the early 1990’s when Environmental Legislation started to be introduced. It uses larger air volumes (300 to 840 l/min or 11 to 30 cfm) at low
