CLEANING SHAPING AIR HOLES
In order to maintain uniform pattern control, the
shaping air holes of the inner ring and the shaping
air cap must be clean and free of any blockage.
It is best to leave the shaping air supply ON
during normal production break cleaning periods.
Shaping air can be reduced to 70 slpm during this
time. This will help stop material from entering
the passage ways.
Periodically (weekly) the outer shaping air cap and
the inner shaping air ring should be removed and
thoroughly cleaned. Use of an ultrasonic cleaner
would make cleaning of hole diameters easier.
Inspect all holes for blockage. Blow holes clear
with compressed air after some time of soaking
in solvent. DO NOT use any type of pick to
clear the holes. Damage may result to parts
and could affect performance of the equipment.
If holes are damaged (oversized holes, blockage,
and gauges) it must be replaced.
