FRD UFI Return Line Filters: Installation Versatility and High Performance<\/strong><\/h3>\n

The FRD series by UFI Filters is designed to provide maximum installation flexibility on the return line of hydraulic systems. These filters can be mounted either on the top of the tank (\u201ctank top\u201d) or externally along the piping, adapting to different system configurations and ensuring effective protection against contaminants.<\/p>\n

Construction Features and Materials<\/strong><\/h3>\n

The structure of FRD filters is robust and designed to withstand significant pressures:<\/p>\n

    \n
  • Body and Cover:<\/strong> Made of anodized aluminum alloy for most models, offering light weight and corrosion resistance.<\/li>\n
  • Large Models (61 & 62):<\/strong> For larger sizes, the cover is made of anodized aluminum while the housing is steel, to withstand high mechanical stress.<\/li>\n
  • Bypass Valve:<\/strong> Integrated and made of polyamide, calibrated at 300 kPa (3 bar) \u00b110%, ensuring fluid flow under critical conditions.<\/li>\n
  • Seals:<\/strong> Standard NBR nitrile, with optional FKM fluoroelastomer available on request.<\/li>\n<\/ul>\n

    FormulaUFI Filter Elements<\/strong><\/h3>\n

    The FRD series uses filter elements from the ERD family, available with different media technologies to meet every filtration requirement:<\/p>\n

      \n
    • FormulaUFI.MICRON (FA, FB, FC, FD):<\/strong> Inorganic glass microfiber with filtration ratings from 5 to 21 \u00b5m (\u00df > 1,000).<\/li>\n
    • FormulaUFI.CELL (CC, CD):<\/strong> Impregnated cellulose, 10 \u00b5m and 25 \u00b5m.<\/li>\n
    • FormulaUFI.WEB (MD, ME):<\/strong> Wire mesh, 25 \u00b5m and 60 \u00b5m.<\/li>\n
    • FormulaUFI.H2O (WR):<\/strong> Specific media for water removal (\u201chydro dry\u201d).<\/li>\n<\/ul>\n

      The filter element is designed to withstand a collapse differential pressure of 1 MPa (10 bar).<\/p>\n

      Performance and Technical Specifications<\/strong><\/h3>\n

      FRD UFI Return Line Filters<\/strong> stand out for their high operating capabilities:<\/p>\n

        \n
      • Maximum Flow Rate (Qmax):<\/strong> Up to 1500 l\/min.<\/li>\n
      • Operating Pressure:<\/strong> Max 2 MPa (20 bar), ideal for heavy-duty applications.<\/li>\n
      • Operating Temperature:<\/strong> From -25\u00b0C to +110\u00b0C.<\/li>\n<\/ul>\n

        Connections and Accessories<\/strong><\/h3>\n

        The range offers a wide choice of connections: BSP, NPT, SAE threads and SAE 3000 psi flanges, with sizes ranging from 1\/2″ to 4″. Filters can be equipped with visual or electrical clogging indicators (2 bar differential setting) for accurate maintenance monitoring.<\/p>\n
