Module filters are ideal for all types of larger ponds. Whether natural bodies of water, swim ponds or even koi ponds, all impose the most rigorous requirements on filter performance. The OASE module filter systems can be extended modularly depending on the requirement, and thus also adapt to increasing requirements. Innovative functions, such as automatic self-cleaning and an extensive range of accessories make the system a perfect solution for the most rigorous demands. In addition, the systems can be easily extended if there is increasing demand.
