Suction Filter

In an effort to help protect the compressors
from contaminants during testing and startup,
AAON is now factory installing pleated
replaceable core suction line filters on the
RNE Series products (55, 65, and 75-140
tons)

Figure 30 - RPE-48-BD filter element

One month after startup, remove the RPE-48-
BD filter element for the lowest possible
pressure drop. Removing the suction line
filter will improve the efficiency and capacity
of the unit. AAON installs isolation ball
valves on both sides of the suction line filter
so the complete system will not have to be
reclaimed/evacuated.

2. Close both shut-off valves to isolate
the suction filter

suction filter section
