If you are wondering what a LVLP spray gun is, you might have been wondering what a HVLP spray gun is as well. Both words are used interchangeably, and while both do spray paint, they do them in different ways. HVLP is an acronym for high-vacuum-laser technology, and is a very advanced method of spraying paint. HVLP is not the same thing as a high-pressure can spray gun, although they do sometimes work hand-in-hand to complete certain jobs.
The low pressure and high volume produced by a LVLP spray gun makes them very easy to operate and easier to handle. A common problem with regular can guns is that they spray paint too thick and leave residues behind. Not so with an HVLP spray gun. HVLP is an acronym for high-voltage-low-pressure technology and refers to the fact that they use a low pressure stream to generate high voltage output. In other words, the amount of voltage output depends on how much spray material is produced.
The two types of LVLP available are called dry-run and wet-run sprayers. Dry run models use a gravity system similar to ban guns to achieve the best spray results. These are more commonly found in professional shops and industrial work environments. They use a vacuum tube to create the high voltage required, but they do not require a siphon feed or an air source to work. These types of guns require frequent replacement of drum heads to keep working properly, as they tend to wear out after constant use.
On the other hand, wet-run or gravity air guns require no air and utilize a pressurized reservoir to achieve the best spray results. These types of guns require constant pumping to maintain pressure. They also work best with gravity feed systems. A gravity feed system uses an air tank to hold compressed air and shoots the compressed air through a hose at the end of a fine needle, creating a vacuum that pulls the fluid through the air line. This type of gun requires less maintenance than the dry run, but they are not as powerful as their wet-run cousins.
The two gauges used in these guns include the psi gauge (pounds per square inch) and the barometer. The psi gauge is what you use to determine the spray intensity. A higher number indicates stronger air pressure. Higher barometric pressure means that the air pressure is higher than atmospheric pressure. Higher psi indicates a stronger air pressure, which can be helpful in foggy conditions.
The other gauge used in this type of spray gun is the air compressor gauge, which measures the overall capacity of the compressor. Higher numbers mean larger air tanks needed for the compressor to achieve the desired spray pressure. The gun may also have a preload setting, which is an adjustment of the settings for the various components of the compressor.
If you are looking for an economical method for transferring a pattern or color, the LVPPS type is the way to go. It consumes a lot less fuel and features a high efficiency motor. It can also be used without a preload setting, which allows increased spray efficiency. This type of spray gun consumes low amounts of power and features variable speed controllers. Speed controls determine the amount of air consumption by varying the rate at which the motor spins.
The final thing you need to know about a LVPPS is the flow control. The gun has an adjustable flow control that allows it to vary the amount of air produced. Increasing the flow control decreases the amount of compressor air needed to achieve the desired pressure and volume low-pressure cycle. A variable-speed fan provides additional cooling and ensures better performance. If you are looking for the perfect solution for your spraying problems, consider investing in a LVPPS.
