General Information
HVLP ProCompt Turbine Sprayers
The HVLP 3800 ProCompt and the HVLP 4900
ProCompt turbines, compressor and spray guns can
spray most coatings or finishes currently being used
for automotive refinish, industrial, aerospace, marine,
wood, plastic, and architectural applications.
To produce high-quality paint finishes, the spray gun
typically utilizes inbound air pressure of 6 psi (0.4 bar,
41 kPa) for the HVLP 3800 ProCompt and 8 psi (0.5
bar, 55 kPa) for the HVLP 4900 ProCompt. A cone of
air, produced by the gun, carries and directs the paint
from the gun to the surface, minimizing overspray and
increasing transfer efficiency. This enables painters to
comply with new clean air laws that are designed to
reduce VOC (volatile organic compounds) emissions,
eases paint application by requiring fewer paint passes
to obtain coverage, and saves on both material and
clean-up time.
See HVLP–Turbine Gun manual 309205 for more
information on the operation and use of the turbine
spray gun.
