Pressure remains high at the inlet – up to 60 psi for typical painting jobs – but is only around 10 psi (pounds per square inch) at the nozzle. 2. Tighten cup, replace seal or check valve. Automotive Hvlp Spray Guns. 2.0 1.8 1.6 1.4 1.3 1.2 High Viscosity Coatings • • Sprayable Fillers … • Do not exceed the maximum working pressure of the lowest rated system component. The H How much less depends on the design of the internal air passages in the gun. A poor tech sheet will just say 10 psig and leave it up to the reader to know what it means. There are also procedures to fine-tune the air pressure based on pattern For In order to properly atomize the paint you should always measure the pressure right at the gun inlet and adjust your regulator to give the proper amount. For Non-HVLP guns this pressure is that which should exist at the air inlet connection to the gun while the trigger is pulled with the air adjustment wide open. maximum for HVLP guns is an environmental legal requirement in order to comply with required HVLP transfer efficiency. Epoxies, tar, glues and other very thick materials will not work well with Fuji paint sprayers since the spray gun is atomizing the coating and can not break it apart into a super-fine mist when it’s too thick. Refer to "Operation" for spraying instructions. Replaceable nozzles are built exclusively for gravity feed applications with the 3M™ Performance Spray Gun System and 3M™ PPS™ Series 2.0 Spray Cup System, offering like-new spray performance with the change of each nozzle. HVLP, in order to comply with legal requirements. Here's my take on setting the proper MACH 1A HVLP (MACH 1AV HVLP) AUTOMATIC AIRSPRAY GUN 6203-XXXX-X MACH 1A ... Do not operate the equipment if you are uncertain about its condition. tests but I haven't found that extra effort to be necessary to get results I BRAND NEW QualSpray 1.0mm Atomizing Set for AM-SERIES HVLP Spray Gun | … not include pressure drops for equipment upstream of the regulator, such as my air filters, It should not be one of these little dinky things where you can't distinguish anything finer than 5 spot gun. The HVLP’s compressor atomizes the paint and sprays it at high speed but keeps the pressure inside of it low. For consider satisfactory. Disassemble and clean gun, and check valve. No. will require 67 psig at the regulator to achieve 50 psig at the gun inlet. compressors only. 110v or 230v No compressor needed. inlet, sometimes a lot less. The 10 psig For non-HVLP guns, that pressure is usually between 40 and 60 psig. HVLP gun inlet pressures required to keep the cap pressure at a maximum of 10 psig are different, depending on gun manufacturers. Remember that it does not matter what a gage back at your regulator says. 1. 3M™ Performance Pressure HVLP Atomizing Heads are designed to deliver excellent spray performance for coatings including stains, primers, base coats, topcoats, clear coats and adhesives. This is interpreted to mean when I have 29 psig and is the pressure existing just behind the air cap and immediately prior to the small orifices in the cap. Because these pressures are different with different guns, the paint manufacturers cannot give an HVLP inlet pressure in their paint technical data sheets. Fifty psig This is applicable to guns supplied from air Inspect cup seal, cup cap, and clean and replace as necessary. To adjust the position of the tube in the cup: 1. basic air pressure for a spray gun:  Here's my take on setting the proper basic air pressure for a spray gun: The paint technical data sheets usually give the recommended pressure "at the gun". Clogged cup pressure tube or fittings. Keep in mind that the recommended nozzle size may vary by paint manufacturer, coating type or depending on your specific application. If you set the pressure Spray Gun TE-S 1.3mm Gravity Feed HVLP Paint Gun with 600cc Cup,high atomizing: Amazon.sg: Home Improvement The wall regulator will read 39 psig. There does not have to be any paint in the gun at the time with one of six available gravity HVLP atomizing head sizes. This does For a HVLP gun a 0-60 one would be a better choice. That is 2. Use a 2" gage marked in 2 psig increments so you can easily read it. Gun too far from surface. The 3M ACCUSPRAY HGP HVLP Gravity Pressure Feed Spray Gun is designed to spray very high solids coatings such as gel-coat, polyester, epoxies, adhesives and boat bottom marine coatings, etc. HVLP Spray Gun and Atomizing Heads for PPS 2.0. Attention - The 7700 is a Non-Bleed spray gun and is not intended for use on Bleed style turbine systems. Follow spraying instructions in the owners manual. Adjusting the pressure this way can make a significant difference in how well the paint is atomized by the gun and consequently how well it flows out on the surface. The configuration is therefore 50 feet of 3/8" hose, two (1 HVLP HGP Spray Gun, 2 - 2.0 mm nozzles, 2 - 1.8 mm nozzles, and Air Control Valve) 1 1 16609 3M ™ Accuspray Atomizing Head Refill Kit, 2.0 mm (4 nozzles) 4 6 16611 3M ™ Accuspray Atomizing Head Refill Kit 1.8 mm (4 Nozzles) 4 6 16571 3M ™ Accuspray Fluid Needle 1 1 16572 3M™ Accuspray ™ Test Air Cap 1 1 There is a major difference in how this pressure is interpreted for non-HVLP vs HVLP guns.
