Dieser darf bei HVLP Pistolen nicht über 10 psi (0,7 bar) liegen, zum Nachweis sind für einige Modelle Prüfluftkappen erhältlich mit denen nachgemessen werden kann. Set the air pressure at the inlet to the gun to the manufactures specs. D. Atomization Air Input This is where the atomization airline is attached. HVLP spray guns are easier to use than most, especially when compared to high-pressure spray guns. For big projects requiring large tip sizes or more than one spray gun operating from a single unit, you can rely on the power and performance of the Impact® 1040. Spray will give the most uniform film thickness making it easy to obtain a smooth finish. So you can expect even less overspray and bounce back with a turbine spray gun. Low Volume Low Pressure Spray Gun (LVLP) Air Pressure Setting. This fully featured sprayer offers the ultimate in functionality and convenience for the longest days and biggest projects. Setting the air pressure to about 28-29 PSI for clear will ensure you having great flow out. This is volume of air pressure per cubic foot. However, it is recommended that a wall regulator be installed for each spray gun to limit the maximum air pressure at the spray gun. This workhorse is perfect for large r... Impact 1140. Highest profitability - SATA® HVLP HVLP = High Volume Low Pressure - low spray pressure technology.Terminology for an internationally recognized low-pressure technology whereby the transfer efficiency rate has to exceed 65%, while the maximum air cap pressure is below 0.7 bar. 3-position rotation to change spray pattern; Conveniently located at the front of the gun; Allows more air pressure into the material cup to spray heavier material; Easily clean and reuse versus replace; Located by gun to reduce clogged valves due to paint contamination ; EasyGlide 2-Finger Trigger and Ergonomic Handle. On an HVLP gun this spec is usually found on the gun and is the maximum PSI it can have while still maintaining the maximum 10 lb at the cap for legal HVLP transfer efficiency (68 %). Most HVLP spray guns will use 10-14 scfm at 40 psi. Figure 5 Pressure Feed Air Cap PRINCIPLES OF AIR SPRAY Spray application is perhaps the simplest method of coating where a sizeable area or volume of material is involved or when intricate shapes and irregular surfaces require painting. Turbine spray guns also operate with much less pressure at the spray head than the compressor HVLP spray guns (conversion type). Most shop air pressure can be 100+ psi and that is too high for proper use of an HVLP spray gun. Adjustable Air Cap. The slightly higher Air Cap Pressure Air cap pressure is air pressure inside the air cap of the spray gun. You are now ready to do a test spray out. Impact 1140.
