Filtrelec EcoDesign Filters – Hydrocarbon filtration from contaminated rainwater up to 1500 L / mn and more. Environment protection for your electrical transformers.

3 functions to improve your retention bunds:

  • Continuous evacuation of rainwater
  • Capture of oil: water contamination output <1-5 mg
  • Instant sealing in event of sudden oil spill


  • Ensures a hydrocarbon concentration of less than 5 mg in filtered water
  • Large filtration capacity
  • Small footprint
  • Oleophilic hydrophobic polymer ensuring permanent capture of hydrocarbons


  • Patented composant: oleophilic and hydrophobic polymer that permanently traps hydrocarbons.
  • An external pre-filter and a safety siphon are required to limit the risk of premature filter fouling due to dust and sediments contained in the water.
  • 4 VERSIONS to meet the throughput needs of interface and oil absorption capacity:
    – Flowrates up to 5 l/min
    – Flowrates up to 15 l/min
    – Flowrates up to 100 l/min
    – Flowrates up to 1500 l/min
    – Higher flowrates upon request


  • FILTRELEC ECODESIGN® filters must be installed at the valve outlet.
  • For higher flow rates, several FILTRELEC ECODESIGN® filters can be mounted in parallel .
  • To avoid the risk of premature clogging, we recommend using a prefiltration solution (external screw-on prefilter, metal cage, etc.).
