Please note that while air flow (CFM) and pressure (PSI) are both important
in determining the turbine
s ability to atomize coatings, pressure is the key.
All manufacturers rate their turbines in the range of 50-170 CFM.
Whether the turbine produces 50 or 170 CFM, it will still have enough air
flow to support the gun. The gun only uses about 25 CFM. Therefore, CFM as
a measure of performance can be misleading. Pressure determines the velocity
of the air moving through the air cap. This creates the turbulence at the
nozzle, and in turn atomizes the coating. The more pressure, the higher the
velocity and the better the ability to break up more viscous coatings.
The air hose often is ignored, but it is a key element of the HVLP system.
Its function–transferring air from the power source to the gun–cannot be
overlooked. The CAPspray hose is specifically designed to withstand heat and
solvents, while remaining lightweight and pliable.
Hose Length
To determine the maximum air hose length with a turbine, use this general
rule of thumb: double the length of hose that comes standard with the
turbine. Example: If 15 feet of hose comes with the turbine, the painter
can use a maximum hose length of 30 feet. Just screw the hoses together to
extend the length.
