Product description The CPF pressure pond filter series is part of the latest generation of pond filters. It combines mechanical and biological cleaning with the latest UV technology. The CPF 50000 bio pond filter ensures a stable biological balance in large ponds and significantly improves water quality, without any chemicals. It creates clear water for ponds up to 100,000 litres without fish or up to 50,000 litres with fish. The filtration system must operate 24 hours a day to optimally promote a healthy climate, lush vegetation and the well-being of the fish. Effective filtering is carried out using various materials such as biological balls, special yellow and blue sponges with different flow rates and a UV-C clarifier. The built-in UV-C lamp ensures algae-free water. A highlight of the filter is the additional fluidized bed system (moving bed), which clearly distinguishes the pressure pond filter from other pressure pond filters in terms of cleaning performance. The maximum water flow rate is 13,000 l/h. Depending on the performance of the connected pump, water can be pumped up to a height of 3 m. This pressure filter has a simple self-cleaning system: on the one hand, this filter system has a dirt indicator, on the other hand, a practical “cleaning” function is provided. In addition, the filters can be extracted very easily using a crank, without having to open the system. In case of heavy soiling, the accessories can also be easily removed and cleaned after opening the lid. With high cleaning capacity, this pond filter system is easy to install, handle and maintain. Directions Let the pressure pond filter run 24 hours a day. UV-C lamp helps control algae. The filter is designed for easy maintenance with a self-cleaning system and dirt indicator.
