General Information

System HVLP Turbine Sprayers

The System 2500

,  3800

, and  4900

 Sprayer,

System ProCart

, and HVLP–Turbine Gun 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 5 psi (0.3 bar,
34 kPa) for System 2500

;  6 psi (0.4 bar, 41 kPa) for

System 3800

;  and 8 psi (0.5 bar, 55 kPa) for

System 4900

. 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 the HVLP–Turbine  Gun manual 309205 for more
information on the operation and use of the turbine
spray gun.
