General Function

The CLEARPOINT® V activated carbon towers use a single pressure vessel, filled with an adsorption material (⅛" activated
carbon as standard) to remove oil aerosol and oil vapor from the compressed air system. As the compressed air flows
across the activated carbon, oil aerosol and oil vapor adsorb onto the surface and pores thus removing it.
During this process, there is no regeneration of the activated carbon. As a result, it will become saturated over time and
must be replaced as it will no longer function to remove oil.
To achieve maximum effectiveness of the activated carbon, pretreatment of the compressed air is required. Oil aerosols
must not exist in high concentration above 0.01 mg/m
humidity not exceeding 30%.
Other conditions that may affect the operating life of an activated carbon tower are:
+
Higher volume flow
+
Higher concentration of oil aerosols
+
Increased operating pressure
+
Increase relative humidity
During operation, there is a possibility for activated carbon solid particles (as fine powder) to be released, that are
particularly abrasive and can be extremely damaging to downstream components and users.
For the above reasons, it is required that the compressed air system before and after the carbon tower, be equipped with
the following:
+
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 + automatic drain
+
1.0 micron filtration grade particulate post-filter (differential gauge optional) with a manual drain
The purpose of the carbon tower is the separation of oil aerosol and oil vapor in compressed air. It is not
intended to separate other contaminants that are present in compressed air. The compressed air output
from this unit cannot be used for respiration purposes of any kind.
