HVLP Help FilesThis is far simpler than airless. There is less to consider and a good HVLP set up can be mastered in no time at all.HVLP stands for High Volume Low Pressure of air NOT paint. An HVLP system does not deliver vast quantities of paint like airless, it delivers small quantities very accurately and without mess. Unlike conventional spray which is considerably 'dirtier' in its output.
Typical uses for HVLP are: doors, kitchen cupboards, spindles on staircases, radiators and radiator covers - in fact any glossed or eggshell areas that are large, awkward or need a factory finish. It is the gun not the air source that denotes it as HVLP. The air source can vary but the best type would be from a turbine. Typically turbine machines are two or three stage units (the higher the more air generated). A compressor will do a similar job but turbines are so much more efficient and very portable. As paint output and fan size are controlled by the gun, the tip size is less important - which is just as well because to change the tip and needle can be expensive. You can spray a 5p coin size fan or enlarge the fan to 10" by adjusting the controls from one tip and needle set if you have a good quality gun. True HVLP outputs at very low pressures, typically 6-8psi (airless would be up to 3000psi). Maintenance on an HVLP machine is minimal. Roughly after every 1,000 hours use you will have to check the air filters, otherwise a clean after each use is all that is needed. |
