FiltoClear 31000 Pressurised Filter | Pond Filters - Water Garden UK
  • FiltoClear 31000 Pressurised Pond Filter

  • The OASE FiltoClear 31000 is a compact pressure filter for ornamental garden ponds, Goldfish ponds and Koi Carp ponds.

    The FiltoClear 31000 is fitted with 3 grades of filter foam media for mechanical and biological filtration. The filter foams are cleaned by simply pulling the top handle up to squeeze the foams, and redirecting the outlet flow via the cleaning valve to pump the dirty water out of the system. The filter has an integrated 60 watt UV lamp, which can be replaced very easily without the need to switch off the pump. There is also a flow-driven cleaning rotor which rotates around the UV glass, keeping it clean.

    The FiltoClear 31000 can be partially buried in ground and the return pipe can be elevated above the level of the filter to provide flow to a stream or water fall return to the pond. The optional FiltoCap Stone Grey Rock Cover can be used to disguise the head of filter.

    Requires Flexible Hose Pipe and will fit sizes 1 ½” (38mm) and 2” (50mm).

The FiltoClear pressurised pond filter range has been overhauled and redesigned by the Oase engineers.  Now featuring an integral 60 watt UVC which can be removed for maintenance even when the pond pump is left running, this also prevents quartz sleeves from being shattered during the annual UVC lamp change.

The internal foam plate assembly has been redesigned to ensure a smoother, more precise compression of the filter foams when operating the maintenance handle to squeeze debris from the filter foams. This new mechanism has reduced the force required to operate the handle by 50% compared to its predecessors. In addition to this, an extra intermediary foam has been included. The purple foam provides a step in size between the blue 'course' foams and red 'fine' foams to prevent the red foams from becoming excessively clogged.
