Metallic bell cups are available in both alumi-
num and titanium. Three different bell cup sizes
are available: 30mm, 57mm, and 70mm. Each
bell cup size has a matching front shroud and
shaping air ring.

The air bearing turbine assembly with bell cup is
mounted to the air manifold assembly with four
socket head cap screws. The front resistor tube
is also attached to the air turbine assembly and
provides the high voltage connection to the mo-
tor shaft and bell.

This unit mounts onto the insulator support rod
assembly with a swivel post. The fluid valve
manifold block is mounted directly onto the back
side, connecting with fluid passages internal to
the manifold. Tube connections for valve con-
trol lines protrude through the rear shroud plate.
The fluid feed tube is screwed into the rear of
this manifold block and the air turbine assembly
mounts to the front with four socket head
screws.

Features which make the Aerobell ® M Rotary
Atomizer advantageous for use in electrostatic
applications include:
• Proven long life turbine motor capable of
speeds up to 55k rpm at minimal air con-
sumption. See "Specifications" in the "Intro-
duction" section of this manual for bell cup
speed ratings.
• 30mm, 57mm, and 70mm diameter bell as-
semblies available for application flexibility.
• Fast color changes are achieved using center
feed fluid delivery, integral brake air, high flow
regulator and the fluid valves which provide for
simultaneous paint push out while solvent
washes the feed tube and bell cup.
• Bell wash is quick and efficient. Solvent usage
is controlled at the feed tube with an internally
mounted solvent valve.
• Less waste to the spray booth, with the dump
valve located internally next to the feed tube.
• More precise fluid regulation, with an (optional)
internal regulator.
• Easy to install and maintain. Hosing and con-
nections are easily accessible at either the
rear of the assembly or by sliding back the
protective rear cover.
• Quick removal of the turbine assembly for off-
line repair.
• Annular shaping air passage design providing
excellent pattern control at minimal air con-
sumption.
• Aerodynamic design for ease of cleaning ex-
ternal surfaces.
• Assembly can be swiveled to provide oblique
spray angles for better paint coverage in diffi-
cult areas of the product.
• Turbine air exhausts behind bell, keeping paint
and solvent contamination out of atomizer inte-
rior and keeping back of bell clean.
• Speed readout (or control) uses reliable mag-
netic pickup for fiber-optic transmission of ro-
tational speed data.
