Superb filtration results are achieved thanks to the 3 different grades of foam; Coarse (blue), medium (purple) and fine (red).

Oase Filtoclear 12000

The Oase Filtoclear 12000 Pond Filter is a highly developed pressure filter designed with ease of use and quality filtration in mind.

Pond water is pumped into a sealed filter unit creating a pressure of up to 0.2 bar. This in turn means that water leaves the filter under pressure, allowing the water to be pushed up to a waterfall, unlike a conventional gravity return filter, which must always be positioned at the highest point of the system.

The Filtoclear pressure filter also has been designed with all the connections and major operating elements in the lid allowing the filter to be partly buried out of sight

  • Pressurised Filter – Pressurised Outlet
  • Cleaning System – For ease of maintenance
  • Attach a hose to discharge waste into drain
  • Safety catch on tension ring
  • Bitron UVC Integrated clarifier
  • Complete Filtration Packages

Summary:

  • Small dimensions, can be integrated into any garden landscape
  • Typically OASE: highest quality materials
  • Guaranteed clear water due to the ideal combination of mechanical, biological and UVC filtration in one system
  • The UVC rays reduce pathogens and flocculate algae cells thus allowing their removal from the water
  • The pressure created by the filter pump can be utilised to power a stream or waterfall
  • The “Easy-Clean-Technology“ makes cleaning the filter simple!

The Filtoclear range embodies a new generation of pressure filters, which is unrivalled in respect of filter characteristics and operating comfort.
