inbound air pressure to produce high quality paint
finishes. The gun produces a cone of air that 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.
Refer to the turbine gun manual, 308-336, for more
information on the operation and use of the turbine
spray gun.
Unpack the Graco Turbine Sprayer from the shipping
carton and inspect for any possible shipping damage.
