What makes the 3M™ Performance Spray Gun system different is the technology inside the quick-change replaceable nozzles. Because paint and coatings never pass through the body of the spray gun – and only the atomizing head – it's like getting a brand-new spray gun every time you swap the nozzle. Get the pattern control, atomization and transfer efficiency you expect from a premium spray gun – all while helping to drive more consistent spray performance across each job, every day. 3M™ Performance Pressure HVLP Atomizing Head Refill Kits are available in sizes 1.1, 1.4 and 1.8 atomizing heads for spraying a wide range of industrial and automotive coatings, including high-viscosity coatings, sprayable fillers, high-build primers, primer surfacers, sealers, single-stage top coats, solvent-based paints, waterborne paints and clearcoats. The replaceable nozzles are used exclusively with the 3M™ Performance Spray Gun system and attach to a supply hose for continuous, bulk spraying from a pressure pot or pressure tank. The atomizing heads attach to the 3M™ Performance Spray Gun whip hose and are tightly secured to the spray gun with a specially-designed locking collar. No additional tools required for changeouts. Simply remove the nozzle from the spray gun, and either appropriately clean the fluid tip or replace it to keep your spray gun performing like new.
