The FILTOMAT M100 series are automatic hydraulic filters, with a self-cleaning mechanism powered by a water-driven turbine. This series of filters is designed to work with various screen types, with filtration degrees from 500 to 80 micron, and is available in 2" to 12" inlet/outlet diameters. These filters units are hydraulically driven; no external power source is required. This feature enables operation at remote installation sites.
Filtering process
Water enters the filter and passes through a pre screen which is designed to protect the cleaning mechanism from large debris. Particulate collects on the main screen and forms a "filter cake". The filter cake causes a pressure differential between the inlet and outlet of the filter.
Self-Cleaning process
The self-cleaning process begins when the pressure differential across the screen reaches a preset level of 0.5 bar. The rinse controller signals an internal flush valve to open. This creates a strong flow of water out of the filter due to pressure in the filter system. The flow of water through nozzles creates a focused back-flushing which effectively removes particles from the screen surface. This water is directed through the suction scanner nozzles attached to a hollow suction scanner shaft, through a turbine, which creates a spiral movement of the suction scanner shaft, and out the exhaust valve. Pressure drop in the turbine chamber and drainage of a piston (in the Modular type units only) forces the suction scanner shaft to move outward. The suction scanner nozzles sweep across the main screen. The combined spin and outward movement ensures that the suction nozzles clean the entire main screen. When the first outward cleaning stroke is completed, a second flushing cycle is triggered, pushing the suction scanner assembly inward to its original position. The combined flush cycle takes 10-15 seconds, depending on the operating pressure.
Control device options
The standard filter is hydraulically driven and does not require an external source of power for operation. An optional electronic controller can be added to enable the operation of multiple filters in parallel or to incorporate additional functions (valve control, output signals to a central control system, etc.).
In an increasingly crowded world, the need for clean water concerns everyone involved in sustaining our quality of life. Society and economy cannot exist without water; because water is life. For more than 40 years, Amiad has helped meet this need by developing a comprehensive line of exceptionally efficient, automatic self-cleaning filters and manual filters for use in industry, municipalities, and irrigation. Amiad provides solutions in more than 66 countries, with seven subsidiaries and sales offices. Amiad's pledge to the filtration industry is to continue providing innovative and dependable systems, quality service and reliable customer support.
