Spray Disc and Nozzle Selection
• Standard nozzles (4) are numbered 3, 4,
6, 8, 10 and 12, designating orifice size
in millimeters. These parts can be
interchanged to produce a pattern
suitable for each job.
• For smaller droplet sizes, reduce nozzle
(4) and/or disc (2) size and increase gun
atomizing air by opening air valve (A)
(counter-clockwise).
• For larger droplets, increase nozzle (4)
and/or disc size (2) and reduce gun
atomizing air by closing air control valve
(A) (clockwise).
