Carbon column is designed to reduce oil vapor and hydrocarbon fractions in compressed air.
Inlet filters and dryers installed upstream of the carbon column ensure that only dripping oil is separated. When using activated carbon air treatment, hydrocarbon vapors from compressed air accumulate in activated carbon open pores and compressed air oil fraction is reduced to a minimum.
Compressed air is fed via a connecting pipe through the inlet to a diffuser, which distributes compressed air over an entire vessel cross-section for optimum efficiency. As air passes through a container filled with adsorbent material, oil vapors as well as odorous and aromatic substances accumulate in activated carbon open pores, thereby reducing its content in compressed air. Purified air then leaves the vessel again through the outlet diffuser.
As temperature increases, activated carbon performance deteriorates as hydrocarbon chains (oils) become shorter and shorter and cannot be absorbed as efficiently. As adsorbent material becomes completely saturated, it requires replacement.
