The only low cost LVLP sprayer around
on January 24, 2009
I researched many HVLP and LVLP sprayers before buying this because I have a small air compressor with only 1.5 Gallon storage capacity and 3CFM at 40psi. Many discussion groups simply tell you that with such a small compressor and low CFM, you can not hope to get good atomization and spray results with any type of gun. But having used this LVLP 1.3mm gun (I have yet to use the 1.7mm nozzle), I was really amazed at the quality of the spray at just 20 PSI setting at the gun inlet with trigger fully pulled and spray pattern set to circular (but 65 PSI setting at compressor). It needs about 25 PSI if you adjust the spray pattern to fan-shaped because some air has to be diverted to shape the spray beam through the nozzle horns. The design of the gun gives you very fine control of the air volume, paint density and spray patterns. If you compare this design with some of the most expensive IWATA guns (e.g. [...]) , they are similar- especially the location of the air-volume control knob. Somehow, I feel that an in-line adjustment creates less turbulence in the internal air stream than the transverse type of adjustment (e.g. [...] By playing around with the 4 parameters of a: Pressure at Compressor, b: Pressure at Gun inlet, c: Paint density, d: Air volume- you can get good atomization and spray results. BUT something has to give- at the fine atomization needed, the amount of materials sprayed is less than that from a higher CFM gun. I guess this is plain physics of balancing the amount of air and paint whilst maintaining atomized droplet size- less air means less paint. For the occasional projects around the house, I feel this reduction in speed of coverage is amply compensated by the nice professional results that you can get out of these LVLP guns. Compared to brushes, the results are much better and the paint covers 3 times more area approx. The guns are well made with chrome all round.
