Spray Application Processes
Atomization Technology Options
Conventional, HVLP and Trans-Tech (LVMP) are all types of Air Atomization technology, each has slightly different operating parameters.
Conventional Air Atomizing
This is the most established method of air atomizing, used on spray guns for decades. It uses high velocity air jets to produce a very high atomization power. However, this speed results in low transfer efficiency due to considerable "bounce-back" and overspray. Air Pressure inside the Air
Cap during use is typically 30 to 60 psi (2 to 4 bar) with typical air consumption of 6 to 25 cfm (170 to 700 l/min).
High Volume Low Pressure (HVLP)
Although not new, this method first became important in the early 1990s when environmental legislation started to be introduced. It uses larger
air volumes (11 to 30 cfm or 300 to 840 l/min) at low pressure to atomize the coating. HVLP has a much higher transfer efficiency than Conventional air atomizing due to the lower air pressures. The droplet sizes produced tend to be slightly larger, sometimes resulting in a lower quality
finish. Officially HVLP is limited by Government Environmental Legislation to a maximum of 10 psi (0.7 bar) atomizing pressure measured at the
air cap.
Trans-Tech (LVMP)
This equipment type was first seen in the mid 1990s and is a mixture of Conventional and HVLP atomization methods. Trans-Tech makes more
energy available for the atomization process but gives a higher transfer efficiency of coating material than the Conventional air atomizing
method. To qualify as Trans-Tech the air cap must be able to transfer at least 65% of the sprayed material to the sprayed component (BSEN
13966 Determination of Transfer Efficiency of atomizing and spraying equipment for liquid coating materials). Air cap pressure is typically in the
region of 20 to 45 psi (1.3 to 3 bar) while using 9 to 20 cfm (250 to 560 l/min) to carry out its work.
Fluid Delivery Options
Siphon-Feed
Siphon-feed hookups (external atomization) use vacuum created at the nozzle to draw fluid
from a cup.

Gun
Advantages: This fluid cup system offers quick material / color changes.
Air
Siphon Cup
Pressure-Feed
This option uses an external pressure source (pressure tank, piston pump, or diaphragm pump)
to force air and fluid from the spray gun nozzle. Air and fluid are then mixed outside the nozzle.
Gun
Air
Advantages: This method delivers higher volumes of fluids than other gun set ups, and will
spray a wider range of materials. It also enables independent control of fluid pressures.

Fluid
Gravity-Feed
On Gravity-feed hookups the cup is located above the gun. The force of gravity pushes the
fluid through the gun.
Advantages: This method offers quick color changes and convenience on small jobs or touchup applications. Gravity guns are able to use all of the coating – reducing waste.

ASME-Code Pressure Tanks
Pressure pots are ideal for pressure fed guns that use Conventional air spray, HVLP, or Trans-tech™
atomization technology. Pressure pots offer smooth flow and mechanical simplicity.
■ ASME-code pressure vessels are called for by NFPA (National Fire Protection
Association) standards.
■ Ideal for “hot potting” plural component coatings.
■ Galvanized tanks offer ruggedness and are suitable with solvent borne
coatings.
■ Stainless steel tanks offer increased chemical resistance and are compatible
with either solventborne or waterborne coatings.
■ Choose from 2, 5, 10, or 15 gallon tanks, depending on your daily coating
consumption and coating container size.
■ 5-gallon and larger tanks can hold standard coating
containers.
■ Choose single regulated tanks if you need to
control only fluid pressure. Choose double
regulated tanks when you’re controlling both
fluid and atomizing air pressures.
Ball Valves
Ball valves provide on-off control with minimal pressure drop. Ball valves have very
limited “throttling” ability; choose fluid regulators when you need precise pressure
regulation.
■ Select ball valves based on maximum pressure they will see on the
inbound side, and connection size.
■ Select stainless steel ball valves for waterborne or solvent borne coatings.
Select carbon steel ball valves for solvent borne applications.
10
Diaphragm Pumps
Diaphragm pumps are ideal for pressure fed guns that use Conventional air spray, HVLP, or
Trans-tech™ atomization technology.
■ Choose ½” Low Pulse models for applications that require smooth flow. Choose
½” Max Flow models for applications that feed up to 2 guns. Choose 1” or 1 ½”
pumps for circulation or bulk transfer.
■ Choose acetal pumps for most solvent borne coatings. Choose stainless steel
pumps for abrasive or waterborne coatings.
■ Industry leading unbalanced air valve gives you virtually stall-free operation.
■ Outfits that include multiple regulation, agitators, and various mounting
configurations are available.
Fluid Regulators
Fluid regulators maintain a smooth and even flow for your
finishing operation.
■ Choose backpressure regulators for circulation or
multi-drop applications. Choose downstream
regulators when you’re spraying immediately
downstream of your regulator.
■ Select regulators based on maximum pressure they
will see on the inbound side, and the desired
maintained pressure.
■ Select stainless steel regulators for waterborne or
solvent borne coatings. Select carbon steel regulators
for solvent borne applications.
