In-line Self Cleaning Equipment with disc filtering elements and 3" valves.

High density polyethylene manifolds. Easy to install. Maximum resistance and durability. Max. flow: 624 m3/h (2748 gpm). Disc Filtration. Maximum safety.

Its patented design and high quality materials used in manufacturing guarantee an extended life with high resistance.

AZUD HELIX SYSTEM. Helix created Centrifugal Action optimizes the filtration performance and reduces backwash frequency and maintenance.

Self-cleaning filtering element.Backwashing uses minimal water maintaining an efficient cleaning action. Large filtering surface. AZUD filtration units available from 5 to 400 micron.

ADVANTAGES

Modularity, Versatility, Compatibility.The system permits a wide range of flows and configurations using a minimal number of components.

Compact assembled systems for easy t ranspor ta t ion and installation.

Manufactured in plastic materials.

Low Maintenance. No tools required. Maximum wear resistance of high quality moving parts.

Water and energy saving.

AZUD HELIX AUTOMATIC backwashes one station at a time. Remaining elements continue filtering.

FILTRATION STAGE: The Helix generates a centrifugal helical effect upon entry into the filter, this moves the particles away from the discs.The water then passes efficiently through the depth of the uniquely designed discs. BACKFLUSHING STAGE: The clean water from the auxiliary filter is introduced from the reverse direction through the filtering element. This decompresses the stack of discs, allowing the discs to separate and backwash efficiently.The solids are expelled from the discs and evacuated through the backwash manifold.The filtration process then restarts with the compression of the discs.

The backwash is controlled by two valves and a controller, which integrate the filtration equipment.

TECHNOLOGY

Modular configurations can be designed to customer preference or space availability. Automation available in 120 V, 220 V or 12 V. Design solutions also available for high or low pressure and sea water/saline water. Compressed air can be used for backwashing.

HOW TO CHOOSE AZUD HELIX AUTOMATIC EQUIPMENTS

1. Determine the required filtration grade (micron).

2. Establish the quality of the water.

3. Calculate according to the following equation, the numbers of filters required with the selected SERIES.

Number of filters =Flow to filter in the installation

Max. Flow per filter

NOTE : The flow rate given by the filter conditions determines the frequency of the backwashing.
