HYDRO DRY UFI Water Removal Filter Elements<\/strong><\/h3>\n

The HYDRO DRY series by UFI Filters is an innovative solution dedicated to the deep purification of hydraulic fluids, with a specific focus on water removal. Free water in oil is one of the main causes of corrosion, fluid degradation, and mechanical failures; these filter elements are designed to act effectively in recirculation (off-line) circuits, filtration carts, and low-pressure lines.<\/p>\n

Technology and Operating Principle<\/strong><\/h3>\n

Hydro-Dry elements use the FormulaUFI.H2O<\/strong> filter media technology, which works through physico-chemical absorption. This technology ensures a high water retention capacity, removing up to 80% of free water<\/strong> present in the fluid.<\/p>\n

In addition to water removal, these elements also provide solid contaminant filtration with a ratio of $beta_{21(c)} > 1.000$. However, for maximum efficiency, it is recommended to pre-filter solid particles upstream using a dedicated return line filter.<\/p>\n

Ideal Applications and Installation<\/strong><\/h3>\n

To achieve maximum water removal efficiency, Hydro-Dry elements must operate under conditions of constant flow rate and constant low pressure<\/strong>. This makes them ideal for use in:<\/p>\n

    \n
  • Off-line filters (e.g. FOF series).<\/li>\n
  • Low-pressure filters (e.g. FMA series).<\/li>\n
  • Mobile filtration carts (e.g. UOW units).<\/li>\n<\/ul>\n

    The use of a clogging indicator calibrated at 130 kPa (1.3 bar) on the filter housing is strongly recommended, to correctly signal the need to replace the saturated element.<\/p>\n

    Range and Compatibility<\/strong><\/h3>\n

    The series includes several families of elements, sized to fit standard UFI Filters housings:<\/p>\n

      \n
    • ERD Series:<\/strong> Compatible with FRD series filters (e.g. ERD31NWR, ERD41NWR).<\/li>\n
    • ERF Series:<\/strong> Compatible with FOF series filters and UOW units (e.g. ERF34NWR, ERF44NWR).<\/li>\n
    • IRF Series:<\/strong> Specific for the UOW \u201cGreen Version\u201d filtration unit.<\/li>\n
    • EMA Series:<\/strong> Compatible with FMA series filters (e.g. EMA11NWR, EMA21NWR).<\/li>\n<\/ul>\n

      Water Retention Capacity<\/strong><\/h3>\n

      Water retention capacity varies depending on element size and oil viscosity. For example, the ERF44NWR model can retain up to 1400 ml of water (with oil at 30 cSt), while more compact models such as EMA11NWR retain approximately 50 ml.<\/p>\n
