Unfortunately, many HVLP spray guns do not perform well at compliance air pressure. Now that the EPA is mandating that most finishing operations switch from conventional air spraying to HVLP, many managers are concerned about maintaining productivity while being in compliance.   The Reality Many painters assume they are automatically compliant if their gun says HVLP on the handle. The reality, however, is much different. Maintaining a gun inlet pressure sufficiently low to keep the gun in compliance is necessary. Most painting facilities cannot tailor their compressed air systems to meet the needs of a single spray gun. Consequently, many HVLP guns are used in a non-compliant manner.   Problems and Pitfalls HVLP spray equipment has been around since the 1970’s. Unfortunately, few designs have overcome the performance shortcomings present since the introduction of this technology. HVLP users often accept low production rates and poor atomization with the resulting poor finish quality to obtain compliance. In response, painters typically increase air pressure or add thinner—both of which are generally violations.   AirVerter - HVLP with a Difference If you are considering HVLP for your coating operation, what decisions are there? Important ones—because many users’ experience with HVLP systems has been less than ideal. What really matters is performance. AirVerter uses patented jet-venturi induction and high-volume open-passage systems to convert high-pressure air to low-pressure air with negligible energy loss. As a result, AirVerter spray guns are much more efficient and powerful.   Most other spray guns simply run compressed air through an orifice which restricts the air and the resultant pressure. Most spray guns are easily taken out of compliance by increasing upstream air pressure and, many spray guns have to be taken out of compliance to perform well as an HVLP gun. AirVerter jet-venturi induction guns keeps the painter in compliance at any compressor pressure.   With AirVerter spray guns, if pressure is increased, its patented inductor stalls to limit air cap pressure to 10 psi or less. Consequently, AirVerter inductor spray guns are compliant at any compressor pressure. AirVerter’s Detach Spray Gun uses a patented open-passage design and cannot be taken out of compliance at up to 80 psi, far above other manufacturers’ specifications. Even more important, AirVerter’s induction and open-passage systems provide the higher energy required to spray materials that many other HVLP systems cannot—and to the performance and productivity levels of conventional air spray equipment.  AirVerter delivers both performance and compliance.   Industrial Spray Finishing Equipment | PAPCE Portable Air Pollution Control Equipment | Prices, Parts & Manuals | About PAPCE | About HVLP | About Overspray | About AirVerter | FAQs | Links | Contact Us | Home   Back to top
