INSTALLATION
AIR FILTER INSTALLATION
The following air filter installation guidelines
are essential for optimum performance:
1. Use 25mm OD (1-Inch OD) minimum in-
bound main air line.
2. Use only recommended pre-filters and
bearing air filters as shown in “Air filtration
Requirements” chart in the ”Installation”
section. Additional system air filtration (i.e.,
refrigerated air dryer) may also be used if
desired.
3. Mount the bearing air filter as close as pos-
sible 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 bearing
air filter. Loose flakes of tape or other seal-
ant 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 and maintain
turbine load capabilities. If the heated air
will exceed 120°F (48.9°C), the heater
must be located after all filters to prevent
damage to the filter media.
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
bulk-headed and their diameters increased
one size. For example: Turbine air should be
increased to 12mm OD from bulkhead plate to
the volume booster.
