BERMAD Irrigation Media Systems Model 4000 BERMAD sand media filtration systems offer a low maintenance and efficient method to filter organic material and fine inorganic particulate from irrigation

1 BERMAD Irrigation Media Systems Model 4000 BERMAD sand media filtration systems offer a low maintenance and efficient method to filter organic material and fine inorganic particulate from irrigation system water sources. When using Basalt or high quality crushed silica as the filtration media, these BERMAD filters can provide up to a 74 micron (200 equivalent mesh) degree of filtration. BERMAD media filters offer much easier installation and maintenance due to the low-profile system configurations. Features and Benefits Low Profile Configuration Easier Installation and Maintenance Double-Chambered Tanks with Mushroom Diffusers Low filtration pressure loss. No gravel pack required Modular Design Flexibility for system layouts with wide range of flow rates Rugged Carbon Steel Construction 125 psi maximum operating pressure Protective Coating 120 micron durable protective coating eliminates corrosion Rubber-coated metal legs isolate filter from the ground to prevent damage to coating Typical Applications Provides primary filtration for drip / micro irrigation systems Primary filter for inorganic particulate from well water sources Primary filter for organic material from surface water sources

2 Principals of Operation Tank s: 16", 20", 24" Filtering Process Process Filtering Process Tank s: 30", 36", 48" Process Filter Inlet Filter Inlet Control Screen Filter A 400-micron extra-strong stainless-steel screen with horizontal inlet and an outlet at 90 0 for additional protection of the system. Each filter is equipped with a drain valve located on the cover, and two pressure-testing ports, designed for checking the pressure differential between the inlet and outlet of the filter without flow interruption.
