Absorption Removal

Absorption Removal

• Typically, most filter media will absorb a small
  amount of moisture from the oil, resulting in
  swelling of the media. This is particularly true
  for cellulose-based media. In fact, examination
  of used filters will often indicate if the
  presence of water is a concern.

• Some filter cartridges with an additional wrap
  consisting of polymer and desiccants are
  available.

• These filters are specifically designed to remove
  water by absorption and remove both emulsified
  and free water, as well as solids. However, the
  elements typically have a limited volume capacity
  and are best fitted to a portable filter cart for
  minor water ingression problems.

• In fact, when a small gearbox is being fitted
  with an expansion chamber type breather, it is
  worthwhile to filter the gearbox with a
  water-removing element to remove any trace
  elements of moisture that may condense out on
  surfaces within the unit when it cools.

• The main disadvantage of absorption removal is
  that it has a limited capability for water
  removal per element. The positive aspect is not
  just its ability to trap solids, but also that it
  is a relatively cost-effective means of dealing
  with small systems that require polishing to
  remove moisture.
