  • Instantaneous adsorption - up to 90 percent of total hydrocarbons removed in a single pass
  • High flow rates
  • Removes dissolved and dispersed oils
  • Low pressure drop
  • Media can hold 250-300 percent of its own weight, with no release of removed hydrocarbons


  • Gas and oil facilities
  • Leisure/commercial shipping bilge water
  • Surface water runoff (truck stops, airports, parking lots)
  • Auto service stations
  • Machine shops
  • Industrial processes
  • Factories and repair shops
  • Car and truck washes


Certain applications may require pre-filtration

Change-Out Frequency

Change-out frequency will depend on the oil burden they have to handle. Because no appreciable increase in pressure drop is observed during service life, the filter must be changed when its adsorption capacity is exhausted.
