Why Choose the Filtreau Gravity Drum Filter
Automatic drum filtration – removes waste before it breaks down
Gravity-fed design – ideal for bottom drain systems
70-micron stainless steel screen – fine mechanical separation
Integrated 40W amalgam UV-C – controls green water and algae
Compact footprint – strong performance without excessive space requirements
This is a true set-and-forget mechanical stage for serious pond systems.
 
How It Works (Simple & Effective)
Pond water enters the drum via 2 × 110 mm gravity inlets
Water passes through the 70-micron stainless steel 316 screen panels
Dirt and debris are trapped on the screen surface
As the screen loads, the system automatically triggers a cleaning cycle
High-pressure spray bar with flat jet nozzles cleans the screen
Waste is flushed into the integrated waste collector
Clean water exits via 1 × 110 mm outlet to the next filtration stage
Debris is removed immediately, preventing nutrient breakdown and improving overall water quality.
