DISC FILTRATION. Maximum security. Its studied design and the materials used in its manufacture guarantee a long life and high resistance.

AZUD HELIX SISTEM. Optimize performance and the frequency and intensity of minimum maintenance.

SELF-CLEANING FILTER. Maximum water savings and cleaning efficiency.

AZUD filtration grades range from 5 to 400 microns.

More modules can be added to increase the flow. The system allows a wide range of possibilities with a minimum number of components.


Equipment already assembled.



No tools required . Maximum resistance, with moving parts not susceptible to wear due to continuous operation.


By not having to backwash a heavy bed of filter media from a conventional filter bed.


It takes retroactively at one station while the rest of the equipment is in the filtration stage, supplying the facility.

Filtration stage: The propeller generates a centrifugal helical effect, which moves away from the particle discs in the water.

The depth filtration process is carried out through the discs.

Water Flow: The filtered water is introduced in the opposite direction through the structures of the filter elements, decompressing the disc stacks and producing backwashing.

The solids expelled from the discs are evacuated through the drain trap.

The filtration stage starts again with the compression of the discs.
