Which is better, HLVP HVLP (high pressure volume, low pressure) or conventional spray guns?

HLVP HVLP spray guns put apply more material on the work and less on in the air as “over spray” which results in more efficiency of sprayed product, reduces cost and improves air quality in the environment. less material being used. Simply put, HLVP HVLP is less expensive to use and more environmentally friendly. Moreover, many new environmental laws require the use of HVLP guns there by thereby eliminating the choice. Please consult the laws and regulations in your state, county, and/or city and purchase the correct spray gun for your intended application. See about HVLP and About Over spray.

What is HVLP?

High- Volume- Low Pressure ins an atomizing process that uses compressed air at pressures ranging from 1- 10 PSI as measured at the spray gun air cap.

What is Transfer Efficiency?

Transfer Efficiency  is the portion of the atomized material that is actually deposited on the work piece. For instance, if in the transfer efficiency on a specific spray gun is 75%, it means that 75% on of the sprayed material in is applied to the work. The remainder in is commonly referred to as over spray, or waste. The transfer efficiency with AirVerter products is ________%, giving customers less waste.

How big does my compressor have to be?

Typically, you will need a 3-HP compressor that operates at 50 PSI and 19.4 CFM to properly supply air to a HLVP HVLP spray gun. We know of customers with 5-HP compressors that are not able to get enough free air (CMF) to operate their HLVP HVLP guns, but this is rare. Since CFM is compressor-specific,  you will need to refer to your compressors specifications to determine if you have enough air. An old rule of thumb is 4 CFM per HP, but this rule is not always accurate. Unfortunately, we do not maintain information regarding compressor output. Please consult your owners manual or your compressor manufacturer.​

What size tip should I use?

This is a difficult question to answer without knowing the exact material, temperature, and conditions you’re working in. Click here to view our spray tip size guide. Please be advised that this is only a guide and you should try a needle/ nozzle size above or below the recommended size to be sure you will obtain the best results.
