High Volume Low Pressure (HVLP) Turbo spray systems are a complete self-contained spray finishing system consisting of three (3) components.
- A blower motor in an enclosure
- A spray gun
- An air hose
There is no air compressor involved or needed with an Apollo Sprayers HVLP turbo spray finishing system. This is an independent standalone system.
When you spray with an air compressor, you can increase or decrease air pressure to adjust the pressure for different paints, coatings and viscosities.
The motors used in HVLP turbo spray finishing systems come in different sizes and power/pressure output commonly referred to in stages. Stages refers to the number of fan levels underneath the motor. The more fan levels (stages) you have the more pressure you get from the turbo motor. Manufactures make a range of motors from single stage up to 6-stages.
Smaller lower powered motors produce a lower maximum pressure to atomize paints and coatings. This means that you are very limited to spraying very easy to apply or thin, low viscosity paints.
As the motor size increases in different models your maximum available pressure also increases, which gives you the ability to atomize a higher viscosity or more complex paint or coating.
It is important to understand that not all paints will be able to be sprayed or to produce desired results with a smaller or lower powered HVLP turbo spray finishing systems. Don’t buy a system that is not powerful enough.
The next component of the HVLP turbo spray finishing system is the air hose. Many smaller and lower priced systems come with a shorter air hose. This limits the range of distance from the motor unit to the spray gun and where you are attempting to spray. The shorter air hose is an attempt to achieve higher pressure from a low power motor, but will only result in sucking more overspray into the motor.
How and where the air hose connects to the spray gun is also important. Lower priced systems only provide a friction style push-in/pull-out connector. This often causes problems when the air hose disconnects when you are spraying and causes finish quality issues.
More expensive equipment generally provides quick connect couplers to the spray gun and motor unit.
Where the air hose connects to the spray gun is often overlooked or even missed by a potential buyer. Low cost and simple HVLP spray guns (plastic or metal) often have an air hose connection only at the top of the spray gun above the paint flow control. This too is done as an attempt to increase nozzle pressure with a lower powered motor.
A professional HVLP spray gun has the air hose connection into the handle of the spray gun. These spray guns also offer many different cup styles as options in addition to having all stainless steel fluid passageways, which are very important if you are spraying waterbased coatings. Most expensive spray guns are also non-bleed. This means the air is shut off when the trigger on the spray gun is not being pulled. Cheaper turbine systems use bleeder guns, which can blow dust around in your spray area if you are not careful.
As your demand for professional end results increases so does the quality of the equipment needed and Apollo Sprayers is here to help.
