HIGH VOLUME LOW PRESSURE.
THIS REFFERS TO THE METHOD IN WHICH THE GUN ATOMIZES THE MATERIAL. CONVENTIONAL GUNS USE HIGH PRESSURE TO ATOMIZE MATERIAL. HVLP GUNS USE LARGE QUANTITIES OF AIR (VOLUME) TO ATOMIZE THE MATERIAL. MANY STATES HERE IN THE U.S. MANDATE THE USE OF HVLP GUNS TO REDUCE V.O.C. (VOLITILE ORGANIC COMPOUNDS) EMISSIONS. IN ORDER TO BE HVLP COMPLIANT A GUN MUST HAVE A TRANSFER EFFECIENCY OF NO LESS THAN 65%. MOST CONVENTIONAL GUNS OF YESTERDAY HAVE A FLUID TRANSFER EFFECIENCY OF 25%-35% RESULTING IN MORE V.O.C. EMISSIONS AND USAGE.
