The QK25 Drum Filter is a high-quality, fully automatic mechanical filtration system designed to provide exceptional water clarity and efficient waste removal for koi ponds and garden ponds.
Manufactured by DVS and supplied under the Queni Koi brand, the QK25 combines established DVS filtration technology with robust construction and dependable performance, offering an excellent solution for pond owners looking to reduce maintenance while improving water quality.
Featuring a patented 120-micron woven stainless steel drum screen, the QK25 effectively removes suspended waste, debris and fine particles from pond water before they reach the biological filtration system. This helps reduce organic waste accumulation and improves overall filtration efficiency.
Constructed from precision CNC-machined polypropylene, the QK25 is designed for strength, durability and continuous operation.
The fully automatic cleaning system monitors water levels and activates cleaning cycles when required, flushing collected waste directly to drain. Adjustable cleaning duration and water level settings allow the system to be configured to individual pond installations.
High-quality, replaceable cleaning nozzles and a removable spray bar make routine maintenance straightforward, particularly in areas with hard water.
The QK25 is supplied in gravity-fed configuration as standard, with a pump-fed option available upon request at no additional cost, subject to lead time.
