Energy-efficient motor with innovative electric control for optimisation of the efficiency level, saves up to 40 % energy. An additional 20% saving in energy is possible thanks to the newly developed. Seasonal Flow Control (SFC for Aquamax ECO 12000/16000). Flow-optimised impeller guarantees maximum hydraulic pump performance and improved displacement of coarse debris. Large surface filter housing allows debris such as vegetation or koi waste up to 10 mm in size to pass through. Ball joint with infinite pivot range facilitates hose connection. Second mechanically adjustable inlet for connection of skimmer/satellite filter for skimming surfaces or pond water. Fully capable of withstanding winter conditions thanks to intelligent frost protection technology. Environmental Function Control (by OASE) protects against dry-run and blocking. Mechanically adjustable and suitable for use in swimponds and bathing ponds.
