Filtreau Excellent Combi Drum 25/30 Pump Fed
Professional Self Cleaning Drum Filter with 80 Watt UV for Pump Fed Systems
The Filtreau Excellent Combi Drum 25/30 Pump Fed is a compact, high performance filtration system designed for medium to large pump fed ponds where automated cleaning and stable water quality are essential.
It suits ponds up to 50000 litres. In this configuration, the unit combines mechanical drum filtration, twin biological chambers and an integrated 80 watt High Output UV clarifier within a single system. As a result, it delivers effective solids removal, reliable biological processing and strong green water control in pump fed installations.
With a maximum flow rate of 25000 litres per hour, the 25/30 Pump Fed version performs particularly well on raised ponds, retrofits and installations where gravity fed layouts are not practical. In addition, the unit includes 3 x 110 mm inlets and 2 x 110 mm outlets, which allow flexible plumbing integration and balanced hydraulic performance.
An industrial 130Nm SPG XL motor rated at 60W 220V drives the stainless steel drum. Meanwhile, a stainless steel float switch continuously monitors water levels. When the screen becomes restricted, the system rotates the drum automatically while the internal 5 bar RVS flushing pump activates. Consequently, it cleans the mesh and discharges waste directly to drain.
Biological Filtration and Media Configuration
The 25/30 Pump Fed model includes twin biological chambers with a suggested maximum combined media capacity of approximately 100 litres.
Because this is a true combination filter, the biological section divides into moving and static stages. One chamber accommodates Hel-X or similar moving bed media such as Hel-X. When you aerate it correctly, it provides high surface area nitrification and efficient ammonia conversion. The second chamber holds Japanese matting, which offers a stable structure for long term bacterial colonisation.
To ensure the moving bed operates effectively, you must supply adequate aeration. For this reason, a Charles Austen ET80 air pump is strongly recommended. The ET80 delivers sufficient airflow to keep up to 100 litres of moving media properly agitated. As a result, it maintains optimal oxygen transfer and consistent biological performance. In contrast, undersizing the air pump reduces media movement and overall filtration efficiency.
The system includes 2 x 50 x 300 mm air bars to distribute air evenly across the biological chamber. However, biological media is supplied separately. Therefore, you can configure the system according to stocking density and pond load.
The integrated 80 watt High Output UV unit operates at 253.7 nm, which represents the optimal wavelength for controlling algae and harmful microorganisms.
Finally, the compact dimensions of 1160 mm x 902 mm x 750 mm make this model particularly suitable for installations where height is restricted.
