The Difference Between HVLP and Conventional Spray Guns for Finishing
It does not matter whether you are refinishing in antique rolltop desk or just creating a simple woodworking project like a wall mount coat rack getting a proper finish on that project requires a little know how and some basic finishing equipment. There are two basic types of finishing spray guns available in the market today the newer high-volume low-pressure guns otherwise known as HVLP and the old stand by the conventional spray gun. Both of these spray systems do a good job of applying finishes but there are a few basic design differences that you will have to take into consideration before making your purchase.
Conventional spray guns operate at a relatively high pressure they connect directly to an air compressor and blast the finish on to your project under the high pressure these guns are capable of very finely atomizing the finishing materials this translates into a nice smooth flow out and leveling of the finishes whether it be a clear finish or a paint finish. Conventional spray guns deliver an excellent finish results but are very inefficient only approximately 30% of the finish ends up on the wood, the other 70% is released into the atmosphere, this obviously has undesirable results both in the wasting of the material and to the environment itself.
High-volume low-pressure guns are relatively new to the do-it-yourself market. These guns were designed to increase transfer efficiency, which is how much of the finish is actually transferred to the wood compared to how much is wasted. Many of the solvents used today in find finishing products unfortunately contribute to poor air quality so in industry today the high-volume low-pressure systems have been in use in many shops and are even mandated by many states and local governments. In the HVLP system air is delivered at a much higher volume but with a very low-pressure so that less finish is blasted off the work piece and into the environment.
There are actually two different types of high-volume low-pressure spray gun systems. The most efficient system operates off from an air turbine this turbine delivers an extremely high volume of air at a very low-pressure in the area of four to six psi. Obviously this system can be quite costly compared to what is known as a conversion high-volume low-pressure spray gun which still runs directly off from an air compressor like a conventional spray gun but it uses a much lower pressure in the area of 25 psi to operate while it is not quite as efficient as a turbine air system it is still much better than a conventional spray gun. For the do-it-yourselfer who already owns an air compressor a conversion high-volume low-pressure spray gun would be the best choice you'll still be able to get a very high quality finish and retain a very good transfer efficiency.
Even if you are using a high-volume low-pressure spray gun to finish your coat rack it is still important to first protect yourself by spraying in a well ventilated area and using proper safety equipment such as a respirator. Many finish manufacturers now produce a line of water-based finishes that are nonflammable and because they use water as a base instead of say lacquer they are much more user friendly and less harmful to the environment.

Usually ships in 24 hours
The Q4 GOLD model with gravity spray gun turbine spray system is the quietest 4-stage HVLP turbine on the market. Please note that this system includes the 9600-G XPC gravity spray gun that features a pattern control knob to adjust the fan size from small round to large and everything in between (Fully incremental). The size of the gravity cup is 400cc (.85 pint). Using patented noise reduction, noise levels have been reduced to less than 50% of standard HVLP turbines. All other specifications are identical to the Mini-Mite 4 model. The new Fuji 9600-G gravity up spray gun is also non-bleed - air only passes through the spray gun when the trigger is pulled. The benefit is less blowing around of shop dust and less paint buildup on the tip of the fluid nozzle. The spray gun features a stay-cool nylon handle, stainless steel fluid passages and an external needle packing adjustment. Obtain a

HVLP Spray Guns - Atomization Technologies - Part 2
In essence, an HVLP gun is still an air spray gun as it uses air as its primary atomization force. Both HVLP and conventional air spray guns use the same two components of compressed air, pressure and volume but in different quantities. The pressure, which is normally noted in terms of pounds per square inch or PSI and volume, which is noted in terms of cubic feet per minute, are both necessary for either gun to work.
Originally HVLP guns where designed to use extremely high volumes of CFM that were generated by turbines rather than compressors. These turbines delivered, in some cases, hundreds of CFM but very little pressure. In order to remain competitive with the turbine HVLP guns, the manufacturers of the traditional air spray guns soon figured out how to convert their guns to HVLP using compressed air rather than turbine air. Today HVLP guns are as common as the old conventional guns.
HVLP technology proved that if you used a lot of volume of air instead of a lot of pressure like conventional guns did, you could not only atomize coatings but also do so more efficiently. The efficiency improvement was mostly related to the fact that the atomized paint particles traveled at a slower speed than paint particles that were atomized with high air pressure. We refer to this characteristic as spray particle velocity. The higher the velocity of the paint particle the lower the efficiency would be.
I like to use the analogy of a tennis ball and a cement wall. The paint particle is representative of the atomized paint particle and the wall represents the substrate being coated. The harder you throw the ball against the wall, the further the ball bounces from the wall. During air spray atomization the paint particle can travel at speeds greater than 30 feet per second or FPS. When the same coating is atomized with HVLP technology, the FPS drops to 10 to 23 FPS. The slower the particle velocity, the less bounce back and over spray, the more efficient the technology will be.
In addition to spray particle velocity, another characteristic that affects guns that use a lot of volume of air such as HVLP is air damming. Here I like to use the analogy of a 2' high by 2' wide by 2' deep box and blocks that are 1' high by 1' wide by 1' deep. In this scenario the box is the inside of a cabinet and the blocks represent a cubic foot of air from your gun. Try to imagine these blocks of air as they exit the spray gun and enter the box. When you spray into the box you are filling it with the blocks of air. The inside area of the box can only hold 8 cubic feet or 8 blocks, but the gun you are using is putting out 20 cubic feet per minute or 20t blocks per minute.
The result is that within seconds you are putting too many blocks into the box and those extra blocks are preventing you from putting in more blocks and they are spilling out all over the place. The volume of air has to go somewhere because it usually can't pass through the item you are trying to spray. The high volume of air from the gun is preventing more air and most importantly, the coating from getting into the box. This is an example of air damming and the higher the volume of air the more damming you will get.
In addition to air damming there is the problem of air turbulence. Turbulence results from sudden changes in wind direction and velocity. This causes the aircraft to bounce and move rapidly in directions that are not intended. Anyone that has ever flown in an airplane or jet has probably experienced it first hand. As the atomizing air exits the spray gun it begins to interact with the coating and the surrounding air in the atmosphere creating turbulence. Additionally, the air and coating interact with the substrates' geometry creating eddies and currents which add to the turbulence. All guns create their own turbulence during atomization but guns with high atomizing pressures or high volumes of air will create more turbulence than guns that use low pressures and very low volumes of air.
So aside from these characteristics that are shared by conventional air spray, HVLP, LVLP and RP guns, one should also understand the benefits and limitations of HVLP. For the most part the benefit is reduced coating usage as HVLP has been proven to increase ones' transfer efficiency. In essence transfer efficiency is than percent of paint solids that leave the spray gun during atomization that actually end up on the substrate and not in the spray booth filters, booth walls or the booths floor. Some manufacturers have seen coating savings per square foot of up to 50% while others may only see savings of 15 to 20%. Much depends on your coating, your environment, your finishers and how well your conventional gun was set up in the first place.
As for the limitations, HVLP guns use substantially more CFM than conventional guns. This means that you will most likely be paying more for electricity to run your compressor at best or you might need to upgrade to a larger compressor at worst. Although the overall atomization of HVLP has greatly improved, atomization quality can be negatively affected by high viscosity and or high flow rates. Most states require that HVLP guns be limited to 10 psi at the air cap because pressures higher than that begin to decrease the guns' efficiency substantially. So if your material is viscous or if you are running high flow rates you may be hampered by this 10-psi limit or by the declining efficiency should you exceed 10 psi.
Low Volume Low Pressure
To help users with limited compressed air availability, some gun manufacturers have introduced Low Volume Low Pressure guns. These guns are designed to reduce spray particle velocity like HVLP guns, but can actually use less air than a conventional gun. This can help reduce the high electricity costs associated with the high cfm demand of HVLP guns. However, it is recommended that you evaluate these guns thoroughly for finish quality and efficiency before automatically switching to this technology. The money you save in electricity may be outweighed by a loss in efficiency or finish quality. Then again, you may find that some of they are actually more efficient or give you a better finish and save you money on your electric bill. The only way to be sure is to try them at your facility, with your coatings and your finishers.
Another advantage of this technology is their ability to deliver pressures substantially higher than HVLP. For companies or industries that are not restricted by state environmental regulations concerning the 10-psi limit, these guns can handle higher viscosities and flow rates than HVLP guns but most likely at lower efficiencies. However, the efficiencies are usually significantly higher than Conventional Air Spray. LVLP guns are considered HVLP compliant but only if operated at 10 psi or less at the air cap.
All of the above low fluid pressure, air spray technologies are available in siphon, gravity and pressure feed formats. However, keep in mind the limited siphoning ability of some of these guns, especially if your material is viscous or if you need to spray at high flow rates. It is also important that you make sure that the gun you select can be operated within the compliant pressure range (10 psi for HVLP) or that it is recognized as a compliant technology, if you are required to do so by any state environmental regulations.
