Filtreau Excellent Combi Drum 80/100 XXL – Pump Fed
Ultra High Capacity XXL Pump Fed Drum Filtration System for Very Large Koi and Commercial Installations
The Filtreau Excellent Combi Drum 80/100 XXL Pump Fed is the largest pump fed model in the Excellent range. Engineered for ultra high flow installations, this XXL combi drum system provides exceptional mechanical separation and substantial biological capacity for very large koi ponds, estate lakes and commercial aquatic systems.
With overall dimensions of approximately 2760mm x 1515mm x 1005mm, this extended chassis offers a significantly enlarged drum chamber and vast biological volume. As a result, it handles high fish stocking levels and heavy debris environments with consistent reliability.
In pump fed configurations, the 80/100 XXL supports flow rates of up to approximately 100000 litres per hour. It is typically suited for koi ponds in the region of 120000 to 150000 litres depending on stocking levels, and ornamental systems up to approximately 200000 to 250000 litres.
Ultra High Capacity Mechanical Filtration with Dual UV
At the heart of the system sits a large stainless steel drum fitted with a precision 120 micron screen. This fine mesh removes suspended solids before they reach the biological chamber. Consequently, the bio stage remains cleaner and more stable even in high feeding regimes.
When debris restricts flow, the stainless steel float switch activates the automatic cleaning cycle. The industrial 130Nm SPG XL motor rotates the drum while high pressure spray nozzles clean the mesh. Meanwhile, the internal RVS 7 bar high pressure flushing pump powers the wash cycle to ensure thorough debris removal.
As a result, the filter maintains stable mechanical separation at ultra high pump fed flow rates.
The 80/100 XXL Pump Fed features dual 80W high output stainless steel immersion UV units operating at 253.7nm. This increased UV capacity provides strong algae suppression and improved pathogen control across large water volumes.
Expanded Biological Chamber and Media Configuration
The 80/100 XXL incorporates an ultra large biological chamber designed to hold approximately 350 to 400 litres of filter media.
For optimal biological performance, we recommend using 300 to 400 litres of Hel-X moving bed media. However, sufficient void space must remain to allow proper tumbling and oxygenation.
Many high end systems also incorporate Japanese matting within the static section to provide additional surface area and final water polishing.
The unit is supplied without Hel-X or Japanese matting. Therefore, media must be purchased separately to suit stocking density and feeding intensity.
Aeration Requirements
To support the large biological volume, the 80/100 XXL is pre fitted with 8 x 50mm x 300mm air bars. These ensure full oxygenation and vigorous media movement throughout the chamber.
For this model, we recommend the Charles Austen ET300 air pump or equivalent high output system to maintain stable aeration under heavy load.
Proper aeration prevents dead zones, supports nitrifying bacteria and ensures long term biological stability.
