The following instructions provide the
necessary information for the proper
operation and preventive maintenance
of the Binks AA4000 Air-Assisted
Airless Spray Gun. Please read and
understand all information in this
document in order to get the maximum
performance from your new AA4000
spray gun.
In the AA4000 spray gun, the paint or
other material to be sprayed is preatom-
ized and forced through the carbide tip
by the typical 1,500-3,800 psi fluid
pressure (with capabilities up to 4,000
psi/275 bar). As a result of the preatom-
izing, the final shaping air supplied by
the air cap produces an exceptionally
fine and even spray pattern. The result
of this spray pattern is an even finish
that lends itself to products that need an
exceptionally fine finish with reduced
overspray and VOC emissions.
