Which Klargester Fuel and Oil Separator Do I Need?

Klargester Fuel and Oil Separator

Klargester's range of fuel and oil separators, designed and manufactured in Ireland, ensure high performance across a range of applications. Surface water drains normally discharge to a watercourse or indirectly into underground waters via a soakaway. Contamination of surface water by oil, chemicals or suspended solids can cause these discharges to have a serious impact on the ground water. Oil separators are installed on surface water drainage systems to protect receiving waters from pollution by oil, due to minor leaks from vehicles and plant.

Separators are used in many applications such as:

  • Garage Forecourts
  • Car Parks
  • Workshops
  • Supermarket / Shopping Centres
  • Distribution Warehouses
  • Car Wash Bays
  • Scrap Yards
  • Car Garages

  • Business/Commercial Parks/Industrial Estate
