The QK25 Combi Drum Filter is a high-quality, fully automatic pond filtration system combining mechanical and biological filtration in one compact unit. Designed for koi ponds and garden ponds, the QK25 provides efficient waste removal, excellent water clarity and reliable biological filtration.
Manufactured by DVS and supplied under the Queni Koi brand, the QK25 benefits from the proven engineering, reliability and build quality of the established DVS filtration range.
Featuring a 120-micron stainless steel drum screen, the QK25 effectively removes suspended waste and debris before water enters the biological filtration chamber. The integrated moving bed chamber provides an ideal environment for beneficial bacteria, helping maintain healthy pond water.
Constructed from precision CNC-machined polypropylene with stainless steel components, the QK25 is built for durability and continuous operation.
The fully automatic cleaning system uses water level monitoring to activate cleaning cycles when required, removing collected waste directly to drain. Adjustable cleaning duration and water level settings allow the system to be configured to individual pond installations.
An external high-pressure cleaning pump is included, alongside a control panel, replaceable cleaning nozzles and a removable spray bar for straightforward maintenance.
