TURBINE SPEED
Turbine speed is determined by the drive air pressure
at the rotary atomizer and fluid flow rate.
Turbine speed can be closed loop controlled using
the fiber optic speed transmitter mounted at the back
of the turbine rotator assembly as a speed input to
remote speed controls such as the PulseTrack 2.
Atomizers
(Refer to "Typical Maximum Safe
Operating Speeds")
All atomizers manufactured after April 6, 1982, bear a
“K” number. That number indicates the maximum safe
rotation speed for that series in tens of thousands.
For example:
9K = 9,000 rpm maximum safe speed,
40K = 40,000 rpm, etc.
If you have an atomizer that does not have a “K”
number, contact your ITW Ransburg repre-sentative
for its maximum safe operating speed.

The disk rotational speed determines
the quality of atomization and can be varied
for different flow rates and viscosities. For
optimum transfer efficiency and spray pat-
tern control, the disk rotational speed should
be set at the minimum required speed to
achieve proper atomization.
Excessive speed reduces transfer efficiency!
NOTE
>
Do not exceed the maximum rated
speed of 40,000 rpm for the 6 inch conical
disk and 27,000 rpm for the 6 inch uni-disk.
This maximum speed includes speed over-
shoot when fluid delivery is stopped. Dam-
age to persons or equipment may result in
over-speed conditions.

Never operate any disk atomizer in
excess of it's maximum rated speed ("K"
number) as listed in the service manual. Ex-
cessive speed may cause the disk to disinte-
grate, causing serious damage and/or injury.

Inspect disk platter daily for wear or
damage. Replace if excessively worn or
damaged. Worn or damaged disk platters
can cause an imbalanced condition and
shorten bearing life. Warranty will be voided
if damaged disks are used.
