The maximum operating pressure and temperature of the standard equipment is 145 psi at 140⁰F.Īmount of water used during backwashing cycle is significantly less than with other types of automatic cleaning filters.

The patented design and the materials used in manufacturing the filters guarantee a long life with high resistance. The backwash is initiated by pressure differential or time. The backwash is controlled by two valves and a controller, which integrate theįiltration equipment. The filtration process then restarts with the compression of the discs. The solids are expelled from the discs and evacuated through the backwash manifold. This hydraulically decompresses the stack of discs, allowing the discs to separate and backwash efficiently. The water then passes efficiently through the depth of the uniquely designed discs.īackwashing Stage: The clean water from the down stream side of the filter elements is introduced from the reverse direction through the backwashing filtering element. Vertical or horizontal design.įiltration Stage: The Helix generates a centrifugal helical effect upon entry into the filter, this moves the particles away from the discs. The system permits a wide range of configurations with a minimal number of components. Video of HELIX EFFECT: Video AZUD Helix Effect The Helix is a centrifugal action device on the inlet to the filtering element which forces the inlet water to spin around the discs inside the filter housing, this forces the larger particles away from the discs reducing the accumulation of solids on the filtration surface, thus optimizing the performance of the discs and reducing the frequency of backwashing The superior quality of the injection molding of the discs provides uniformity of the discs which results in high efficiency at the selected micron level. The width and support structure of the discs provided high resistance to the pressure differential across the filtration surface. The MG discs provide depth filtration resulting in very high efficiency at a given micron level. The discs are available in Multi-Groove (MG) or Wall type depending on the application they are needed for. Only a portion of the water is used for backwash in multi element systems.

See special options available on the AZUD HELIX DISC FILTERS below. A determined pressure differential activates an automatic hydraulic backwashing system. The Helix creates centrifugal action which spins the larger particles away from the discs, and the discs provide a high level of filtration. The filter uses the patented Azud Helix and Azud Discs to efficiently filter the water. The AZUD HELIX AUTOMATIC filtration range is built for high efficiency with low maintenance and absolute safety. The AZUD HELIX AUTOMATIC range of DISC filters offers multiple combinations to achieve an efficient and economic filtration solution, which can be adapted to various water conditions in the industrial, HVAC, municipal, environmental, agricultural and landscaping markets.
