OLSW Series Offline Filtration Units: Complete Protection Against Contaminants<\/strong><\/h3>\n

The OLSW offline filters by :contentReference[oaicite:0]{index=0}<\/strong> represent an advanced solution for hydraulic fluid maintenance. These units are specifically designed to tackle contamination at its source by removing both solid particles and large amounts of water from oil.<\/p>\n

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

The unit draws oil from the reservoir via an integrated gear pump and directs it through the filter element. Stauff technology uses special spin-on elements that act as pre-filters, removing most of the water and larger contaminants. In a second stage, the fluid passes through the Stauff Micro Filter, where final removal of water and solid particles down to 0.5 micron<\/strong> takes place. This prevents the catalytic reaction between water and solid particles, ensuring extended oil service life.<\/p>\n

Design Features and Configurations<\/strong><\/h3>\n

OLSW systems are highly modular. Contrary to previous indications, the series is divided according to the number of housings and the length of the filter elements:<\/p>\n

    \n
  • OLSW 1 (Single Housing):<\/strong> Flow rate 2.1 l\/min (L.30 version) or 4.2 l\/min (L.60 version).<\/li>\n
  • OLSW 2 (Double Housing):<\/strong> Doubled capacity, with flow rates up to 8.4 l\/min.<\/li>\n
  • OLSW 4 (Quadruple Housing):<\/strong> For high-demand applications, with flow rates up to 16.8 l\/min.<\/li>\n<\/ul>\n

    The standard electric motor is three-phase (230\/400 V AC, 50 Hz, 1360 rpm).<\/p>\n

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

    OLSW units provide stable performance for both new and existing installations:<\/p>\n

      \n
    • Flow rate:<\/strong> From 2.1 l\/min to 16.8 l\/min depending on the model.<\/li>\n
    • Pressure:<\/strong> Maximum housing pressure 20 bar. Max differential pressure 6.2 bar (without back pressure).<\/li>\n
    • Viscosity:<\/strong> Designed to handle fluids with viscosities between 20 and 160 cSt<\/strong>.<\/li>\n
    • Temperature:<\/strong> Maximum fluid temperature +80\u00b0C.<\/li>\n<\/ul>\n

      Filter Element Flexibility<\/strong><\/h3>\n

      The unit is compatible with a wide range of SRM-type replacement filter elements, including:<\/p>\n

        \n
      • Super-absorbent polymers (A):<\/strong> 10 micron (water absorption).<\/li>\n
      • Inorganic glass fiber (G):<\/strong> 1, 3, 6, 12, 25 micron.<\/li>\n
      • Cellulose (H):<\/strong> 0.5 micron (standard).<\/li>\n
      • Filter paper:<\/strong> 10, 25 micron.<\/li>\n
      • Wire mesh:<\/strong> 125 micron.<\/li>\n<\/ul>\n
