Innovation is a core value at Filtersafe and Mayan. From the beginning, Filtersafe has been an innovator in automatic filtration, developing many patented technologies, such as smartweave™ screens, nozzlex® screen cleaners, and the EVERCLEAR cleaning sequence to maximize filtration.
The endless configurations and versatility of our products make the filtration and treatment processes easier for distributors and end-users, minimizes the footprint and increases efficiency for every type of project.


Optimizing the performance, frequency and intensity of maintenance In the ‘90s, Azud revolutionized the filtration sector with its patented Helix anti-clogging device. The helix is the fundamental element of the system, the result of careful study of hydro-efficient design. Placed in the base of the cartridge where the water passes, the device’s “wings” generate a helical centrifugal effect inside to move a large amount of suspended particles away from the discs. This translates into increased water savings and reduced frequency and intensity for maintenance.

The Helix Automatic DLP system adapts to installations where pressure conditions are limited to the self-cleaning system, reducing the pressure and water amount needs during backflushing to optimize the filtration process and improve overall energy costs.
The Helix centrifugal action device optimizes performance and reliability in a low-maintenance filtration system.

Self-cleaning filtering element. Maximum water savings and efficiency in backwashing.

Modular. Versatility, compatibility. Allows for a wide range of configurations using a minimal number of components.

Maximum reliability. Sturdy design and materials guarantee long life and high resistance.

High-quality manufacturing. High-density polyethylene manifolds for maximum resistance and durability.

Large filtering area and wide range of filtration grades. Discs from 5 to 400 microns adjust to variety of applications.

Easy transport and installation. Pre-assembled equipment; fairly compact.

Low maintenance. No tools required for maintenance. Maximum resistance with movable parts not susceptible to wear due to continuous operation.

Additional Information

Filtration stage: Water entering the filter enters through the Helix device, generating a centrifical effect that pushes particles in the water away from the stacked discs. Water passes through the grooves on the surface of the discs, leaving fine particles in and between the grooves.
Backflushing stage: Filtered water is introduced from the opposite direction through the filtering element structure, decompressing and spacing the stacked discs, which causes perfect cleaning of the discs’ grooves.
Solids expelled from the discs are evacuated through the drainage manifold. Filtration begins again with compression of the discs.
Backflushing is controlled by integrated drainage valve and a controller
