What is an LVLP Spray Gun? Low Volume, Low Pressure vs High Pressure. https://billious.com/best-lvlp-spray-gun/ LVLP stands for Low Voltage, High Pressure, and is the trade name of a compressor/siphon system used for filling air in lines that have pressure needs. It's a fine way to maintain pressure in an air conditioning system or other pneumatic applications. The basic concept is that the compressor sprays air into a larger tank, but doesn't draw in air from the tank in order to do so.The high flow compressor in a SIP system (supply pressure) provides constant air flow to the tubing while it fills the lines at a low pressure. The compressor CFM in a LVLP spray gun supplies a steady flow of air along the line without the high pressures associated with a supply pressure setting. You may notice the "Siphon" in" LVLP Spray Gun" is mispelled as "Sip Gun."In practical terms, a LVLP sprayer is really only useful if you use a large system. That's because the constant flow pump requires a lot of for high velocities. A smaller compressor has a much lower RPM and therefore will not work as fast. So you'll get more usage out of a low RPM compressor, although you might end up paying more money for it.One type of this system that people often use is a low velocity compressor. It uses a low pressure system so that the air goes a lot slower than the paint and doesn't saturate the surface as quick. There is more volume out there per cycle with these systems, so they don't need to use a lot of air to produce a high pressure. They also are more stable than other types. So a combination of a high pressure compressor and low velocity compressor will produce better results.You might think that the lower pressure needed to saturate the paint would lead to less overspray; but the opposite is actually true. With a lower pressure, you get less paint into each stroke. That's because the pump is slower. With a higher pressure, the paint gets faster and goes further. That leads to more coverage for less paint.Another common use for a LVLP or small compressor is to clean out large particulates of dust or gunk from the compressor line. An air compressor is good at getting air down into those areas, but it just can't clean out enough dust or dirt to make it efficient. You can do the cleaning with a lower pressure or even lower temperatures, but you have to be careful. If the temperature is too high, you can overheat the compressor and damage it.<img width="377" src="https://www.nuagane.co.uk/ekmps/shops/cf3268/images/lvlp-silver-blue-spray-gun-1.4-needle-set-up-save-on-your-paint-costs-free-post-961-p.jpg">Another good application for the LVLP Spray Gun is for cleaning up an indoor air compressor. This is good if you have an air compressor but not a propane one. If you have both, you may find that using the spray paint is much more efficient at producing the same amount of paint. It may take a bit longer, but it is usually not as much of a challenge to use. In fact, your air compressor will probably take much less time to clean it than the gun would. Just be careful.And finally, another good use for the spray guns is on very large jobs. If you have to clear a parking lot or something similar, you can pump much more air than you would with a smaller compressor. Of course, since you are using such a large amount of pressure, you will need a really good air pressure regulator. Look at air volume, pressure, and flow and you should be fine.
