What is the difference between HVLP (High Volume Low Pressure) and Conventional Paint Sprayers?
A. With Conventional Paint Sprayers, the paint spray gun is supplied with high pressure air at 40-80 psi. This high pressure is used to break up the paint stream as it leaves the gun and to propel the paint particles onto the part. Unfortunately, due to this high pressure, much of the paint particles blow past the parts or bounce off the parts. This is called “overspray” and “bounce back”, which is normal for conventional paint spray equipment. The “transfer rate” of this type of system is quite low, as most of the paint particles are blown about the room, instead of onto the product. Low transfer rates mean a considerable amount of airborne dust in the air, a dirty environment and high paint and thinner consumption, in addition to dust in the final finish. Q. What is “Transfer Rate”? A. Transfer rate is stated as a percentage and refers to the amount of actual material (paint and thinner) that is applied to the product being painted. Obviously, it is advantageous to get as much materi
