Aerbell 33 Rotary Atomizer - Maintenance

MAINTENANCE
In addition to the above "Warning", which relates
to potential safety hazards, the following infor-
mation must be observed to prevent damage to
the equipment.
CLEANING PROCEDURES
Internal Fluid Path Cleaning
Cleaning the incoming paint line (from paint supply
source such as color manifold through the fluid
valve block and bell assembly):
† The maximum flow rate of 500 cc/minute
must not be exceeded during a flush routine.

!
† Do not immerse the Aerobell 33 turbine
in solvent or other liquids. Turbine compo-
nents will be damaged.
† Bearing air must be on during all clean-
ing procedures to protect the air bearing
components.

† Electrical shock and fire hazards can ex-
ist during maintenance. High voltage supply
must be turned off before entering the spray
area and performing any maintenance pro-
cedures on the atomizer. Spray booth fans
should remain on while cleaning with solvents.
† Never touch the atomizer bell while it is
spinning. The front edge of the bell can eas-
ily cut into human skin or cut through gloves
and other materials. Be sure the atomizer
bell has stopped spinning before attempting
to touch it. Approximate time for the bell to
stop spinning after turning off turbine drive
air is three minutes.

Turn off high voltage and turn on the trigger valve.
With the bell spinning, flush cleaning solvent
through the incoming paint line and through the
manifold passages, through the fluid tube and onto
the bell. The spinning bell will atomize the solvent
and clean out the bell passages. If desired, open
the dump valve to flush through the dump line for
a faster and contained system flush.
Internal Fluid Path Cleaning
(Without Cleaning the Incoming
Paint Line)
Turn off the high voltage and trigger valve. With
the bell spinning, turn on the solvent valve to al-
low cleaning solvent to flow through the manifold
passages, through the fluid tube, and onto the
bell. The spinning bell will atomize the solvent
and clean out the bell passages.
With the solvent valve open, open the dump valve
to clean the remaining manifold fluid passage and
to flush the dump line if desired.
External Atomizer Surface Cleaning
• Verify that the high voltage is turned off.
• All external surfaces may be cleaned using a
mild solvent and lint free rags to hand wipe
the Aerobell 33. Turbine drive air must be off,
but leave shaping air and bearing air on. Be
careful not to drip solvent into the opening
behind the bell.
• If conductive, polar solvents are used to clean
the Aerobell 33 unit, all residue must be
removed using a non-conductive non-polar
solvent (ex., high flash naphtha).
