SHAPING AIR KIT #3
A12874-08/09 Dual Flex Shaping Air Kits
(for 65mm Bell Cup )
Both shaping air outlets supply air that is coun-
ter to the rotation of the bell cup. This combi-
nation will provide a pattern size from 3-inch to
10-inch (76mm - 254mm) depending on bell
rotation speed, fluid flow, and air flow. Both
sets of shaping air holes are independently
controlled. The inner set of holes are supplied
by connecting the “blue” tube labeled “SAI” on
the tubing bundle to a regulated air source.
The outer set of shaping air holes are supplied
by connecting the “gray” tube labeled “SAO”
on the tubing bundle to a regulated source.
The air supplies work in combination with each
other to provide desired results. This combina-
tion of shaping air can be used with any 65mm
bell cup.
SHAPING AIR KIT #4
A12089-03/04 Shaping Air Kits (Dual Air -
Direct Charge) for Use With 30mm Bell Cup
Only
This combination provides for two air sources
to gain better pattern control, eliminates a sec-
ondary “ghost” pattern, and the ability to pene-
trate into deep cavities. The first air is con-
nected to the “blue” tubes labeled “SAI” on the
tubing bundle. This air exits through an annu-
lus between the outside diameter of the ball
cup and the inside diameter of the shaping air
manifold. The second air is connected to the
tube labeled “SAO” and is “gray” in color. This
air exits a concentric series of holes at the
front of the atomizer. This shaping air combi-
nation can be used with either the aluminum
30mm bell cup or the Titanium 30mm bell cup.
“Air Flow” information can be found in the
“Introduction” section of this manual.
A minimum of 70 slpm (2.6 SCFM) should al-
ways be kept flowing in the inner shaping air
passage to keep the face of the applicator
clean during manual cleaning breaks.
