IPU Diesel Defence DDF6 fuel polishing unit

The DDF6 Fuel Polishing System is a powerful high flow fuel filtration and polishing module utilizing a two-stage filtration principle, which ensures that solid contamination, microbial activity and water ingress can all be effectively removed in a single pass.

  • Flow rates up to 500 l/min.
  • Filtasorb2 water removal media able to remove 100% free water and 99% entrained water from diesel fuel.
  • System rated at 10 bar working pressure with safety shut-off at 3.5 bar.
  • Optional secondary outlets allow the filters to be bypassed.
  • Leakage or Spillage alert with float switch located in drip tray.


DDF6 Fuel Polishing System Features & Benefits


Faster solution, greater savings

Stored fuel can develop solid particulate, water and diesel bug contamination if left for greater than 12 months without being replaced or cleaned.

The DDF6 Fuel Polishing System delivers a powerful throughput of up to 500 l/min. The DDF6 removes both solid particulate and water in a single pass ensuring fuel is clean and dry, is within specification and ready for use when required.


Challenging applications demand the highest performance


For equipment working in dirty locations in large operations across the globe it is critical that your filtration system can perform in the most challenging environments. The DDF6 delivers with each housing being hydrostatically pressure tested to the European Pressure Equipment Directive, 97/23/EC.
