Main characteristics of pool sand filters<\/b><\/h2>\n

This type of filter uses sand as a filtering agent inside its tank.to retain the impurities present in the pool\u2019s water.<\/span><\/p>\n

At GRE, we offer you a range of compact, easy to install and use pool <\/span>sand filters<\/b>. They do not require special care and can be fitted to any removable pool.<\/span><\/p>\n

The <\/span>sand filter<\/b> monobloc holds a complete filtration set that includes:<\/span><\/p>\n

– Pump.<\/span><\/p>\n

– Filter (with a capacity of 4,000 liters per hour at 180 W power).<\/span><\/p>\n

– 5-Way selector valve.<\/span><\/p>\n

– Manometer (pressure gauge).<\/span><\/p>\n

It is mounted on a plastic bench with all the necessary pipe fittings. Our pool <\/span>sand filters<\/b> are also certified under the European standard, guaranteeing compliance with the safety regulations in force.<\/span><\/p>\n

 <\/p>\n

Pool sand filter operation<\/strong><\/h2>\n

This type of pool filter has a selector valve that enables it to perform several functions. They are:<\/span><\/p>\n

    \n
  1. Backwash<\/span><\/li>\n<\/ol>\n

    In this position, the water inside the filter flows in the opposite direction of the filter and into the drain. This function removes any impurities from the <\/span>sand filter<\/b>. The process will be completed when the water being drained becomes clear (approximately 2 minutes). We recommend you use the backwash function at least once a week.<\/span><\/p>\n

     <\/p>\n

      \n
    1. Rinse<\/span><\/li>\n<\/ol>\n

      Upon completing the backwash process above, place the valve in the \u201cRinse\u201d position for 30 seconds to completely rid the piping of any dirt\/impurities. Once that is done, place the valve lever in the \u201cFilter\u201d position.<\/span><\/p>\n

       <\/p>\n

        \n
      1. Filter<\/span><\/li>\n<\/ol>\n

        In this mode, the water is filtered and returned clean through the return valve into the pool. This is the function\/position the filter unit will remain in most of the time.<\/span><\/p>\n

         <\/p>\n

          \n
        1. Drain<\/span><\/li>\n<\/ol>\n

          In this position, the water goes directly into the drain without passing through the filter.<\/span><\/p>\n

          This option is ideal:<\/span><\/p>\n

          \u2013 If you notice a lot of dirt accumulated at the bottom of the pool.<\/span><\/p>\n

          \u2013 To lower the water level when (for any reason) it is above the skimmer<\/a>.<\/span><\/p>\n

          \u2013 To drain the pool completely.<\/span><\/p>\n

           <\/p>\n

            \n
          1. Shut<\/span><\/li>\n<\/ol>\n

            In this mode, the water is shut off from the filter unit. It is recommended for winter or prolonged periods without use of the pool.<\/span><\/p>\n
