OPERATION
W A R N I N G
!
Operators must be fully trained in safe
†
operation of electrostatic equipment. Oper-
ators must read all instructions and safety
precautions prior to using this equipment (see
NFPA-33, EN 50 176)
Electrical discharge on a high electrical
†
capacitance fluid/paint system can cause fire
or explosion with some materials. If arcing
occurs when a specific material is used , turn
the system OFF and verify that the fluid is
non-flammable. In these conditions, the sys-
tem is capable of releasing sufficient electrical
and thermal energy to cause ignition of specific
hazardous materials in the air.

When turning the turbine on, bearing air
†
must be present. Likewise, bearing air must
remain on when the turbine air is turned off
until the turbine stops spinning. Never turn
off bearing air to cause the turbine to stop
spinning. Brake air can be used to slow the
turbine (see "Brake Air" in this section. Wait
for the turbine to stop spinning before turning
bearing air off.

As with any spray finishing system, operation
of the Aerobell 268 involves properly setting the
operating parameters to obtain the best finish
quality for the coating material being sprayed
while maintaining correct operation and reliability
of the equipment used. Adjustments to operating
parameters, which cover spraying, cleaning, and
ON/OFF control, include the following:
• Coating Materials
• Fluid Flow Rate Control
• Fluid Valve / Trigger Control
• Turbine Speed
• Shaping Air (pattern control)
• Electrostatic Voltage
• Target Distance
TURBINE SPEED
The speed of the turbine is determined by the air
inlet pressure. See "Turbine Air Pressure, RPM,
SCFM" in the "Installation" section for more infor-
mation. The desired speed will depend upon the
type of coating material and various application
requirements.
C A U T I O N
!
† Excessive speed will cause air turbine
damage. Do not exceed the maximum rated
speed of 60,000 rpm.
