Filtreau Combi-NEXT Drum Filter with UVC – Pump Fed with NEW XL Motor
Includes 100 Litres of Moving Bed Media – Exclusive Upgrade
For a limited time, we are including approximately 100 litres of high-performance moving bed media with the Filtreau Combi-NEXT Pump Fed model at no additional cost. This provides immediate biological capacity from installation and allows the system to stabilise more quickly under feeding load.
The Filtreau Combi-NEXT Drum Filter with UVC – Pump Fed is a fully automated mechanical and biological filtration system designed for koi ponds up to 45m³, depending on stocking density. This version is engineered specifically for pump-fed installations where the filter sits above pond water level.
Water is pumped from the pond into the Ø400 x 430mm stainless steel drum chamber fitted with a 120 micron screen. Solid waste is removed immediately before it can degrade water quality. As debris restricts flow, the stainless steel float switch activates the automatic cleaning cycle.
The NEW XL SPG motor delivers 130Nm of torque, ensuring smooth drum rotation even under heavier waste loads. This pump-fed version connects to a mains water supply for drum cleaning and does not include an internal rinse pump. During the cleaning cycle, spray nozzles flush debris from the drum screen using mains pressure, discharging waste directly to drain.
Biological Capacity and UV Performance
After mechanical separation, water enters the substantial 350 litre moving bed biological chamber. For optimal performance, this chamber is designed to hold approximately 200 litres of moving bed media.
At full maturity, a correctly sized media load can process significant feeding levels while maintaining ammonia and nitrite stability. For correct aeration and movement, the chamber should typically be filled to around 70 percent of total volume to allow proper boiling action.
As part of our current promotion, this model includes 100 litres of moving bed media free of charge. This provides half of the recommended biological capacity from day one while leaving room for expansion to the full 200 litre load if required for higher stocking or feeding regimes.
The integrated 40W Amalgam High Output UV-C module operates at 253.7nm and includes an LED indicator for lamp monitoring. It suppresses algae spores, bacteria and harmful microorganisms as water passes through the system, improving clarity and supporting healthier pond conditions throughout the year.
We recommend using the Charles Austen ET100 Airpump with this filter system.
