Rotary Drum Filter (RDF) is an automated filtration system for Koi ponds. It acts as an excellent mechanical filtration to automatically remove the debris and fish waste out of the water column quickly and regularly through a standard 70 micrometer fine mesh with automated washing cycles to reduce contaminants and maintain crystal clear water.
With FREE-Drum-Filter, you no longer need to perform painstaking tasks such as cleaning filter media pads or cleaning settling chamber, backwashing mechanical filters or changing the water periodically. FREE-Drum-Filter will take care all of those tasks automatically. It quickly remove waste from water column that help reduce toxins from the pond and help your fish grow optimally and keep your pond water crystal clear.
FREE-Drum-Filter is designed by engineers that are also pond-enthusiasts and longtime koi keepers who understand what it takes to effectively maintain koi ponds. After many years of research and testing in many different koi pond environments, we have come up with the products that assure the highest level of functionality that are still simple and easy use and be maintained by the pond hobbyist with no engineering background.
