The Azud Helix automatic FT200 self cleaning filtration system is composed of 1 – 10 x 2” filter pods installed in-line performing in-depth filtration. The system includes 2” backwash valves operating on Azud’s DLP low pressure technology and inlet and outlet manifolds. When multi-filters are installed clean filtered water is used for backwashing the rest of the filters in the train ensuring the system continues to filter during backwash. The Air Assisted (AA) version takes compressed air stored in an auxiliary tank, mixed with water to provide a more aggressive and effective backwash while saving 80% of wasted backwash water.

The patented Azud Helix anti-clogging deflector provides reliable filtration through centrifugal separation, reducing backwash frequency and reducing waste water.



  • Water flows from the inlet manifold to the inside of the filter, passing through the anti-clogging deflector AZUD HELIX, which throws the heavy particles away from the disc stack, avoiding the quick clogging of the filter and minimising the backwash frequency.
  • Water flows OUT-IN through the disc stack to the outlet manifold while particles bigger than the filtration degree are trapped in the discs


  • During the automatic backwash, a water-air mix is made, providing a more energetic and effective cleaning with an 80% water saving.
  • The water-air mix flows IN-OUT, decompressing the disc stack.  High-speed flushing water flowing through the spray nozzles, creates a tangentical cleaning effect that flushes out the trapped particles.
