Each applicator must have its own
filter for bearing air. Recommended:
RPM-418 or equivalent.
With the exception of fluid, dump,
and bearing air, all other pilot and air
supply lines should be bulkheaded and
their diameters increased one size. For
example: Turbine air should be in-
creased to a 12mm OD from bulkhead
plate to the volume booster.
AIR FILTER
INSTALLATION
The following air filter installation guidelines
are essential for optimum performance:
1. Use 25mm OD (1-inch OD) minimum
inbound main air line.
2. Use only recommended pre-filters and
bearing air filters as shown in "Air Fil-
tration Requirements" chart in this sec-
tion. Additional system air filtration
(i.e., refrigerated air dryer) may also be
used if desired.
3. Mount the bearing air filter as close as
possible to the RMA-303. (DO NOT
mount further than 30-feet (9.1 meters)
away.)
4. DO NOT use tape, pipe dope, or other
thread sealant downstream of the bear-
ing air filter. Loose flakes of tape or
other sealant can break loose and plug
the very fine air holes in the turbine air
bearings.
5. Air heaters are highly recommended for
use in the system to minimize the effect
of excessively humid conditions. If the
heated air will exceed 120
o
F (48.9°C),
the heater must be located after all fil-
ters to prevent damage to the filter me-
dia.
