Inlet air entering the carbon tower must be pretreated. Oil aerosols must not exist in high concentration
above 0.01 mg/m

and, the compressed air should be pre dried with a relative humidity not exceeding 30%.
Not following this practice will lead to overloading the carbon tower, permanently reduce the capacity, and
cause rapid deterioration of the activated carbon material.
It is required that the compressed air system before and after the carbon tower, be equipped with the follow-
ing:
+
30% RH
or better
pre-dryer
; achieved with either a refrigeration or desiccant dryer
+
0.01 micron
filtration grade coalescing
pre-filter
with differential pressure gauge and float drain
(automatic drain optional)
+
1.0 micron
filtration grade particulate
post-filter
(differential gauge optional) and manual drain
Activated carbon dust traveling downstream of the carbon tower may cause contamination and/or accelerat-
ed wear to other components and equipment. Therefore, a particulate post-filter should be used to prevent
carbon dust from traveling downstream. Activated carbon is considered a nuisance dust and proper precau-
tions should be taken during handling (refer to applicable SDS sheet).
5.
IMPORTANT!
Bypass piping is necessary. Only bubble tight valves should be used.
6.
Points of access should be provided upstream and downstream of the carbon tower for
pressure and temperature monitoring prior to finalizing the installation. These access points can
also serve as periodic monitoring of oil aerosol and oil vapor carryover, to determine whether the
carbon tower is performing optimally. We recommend using METPOINT® instrumentation to
ensure accurate measurements.
7.
All piping must be adequately supported and at least of equal size to the carbon tower
connections.
Before any attempt is made to operate the carbon tower, the operator must thoroughly read and
understand this installation and operation manual.
