Filtreau Pump fed Combi-Filter PF20 Plug&Play (Inc rinsepump)

The Filtreau Combi PF20 is a compact, low‑maintenance filtration system designed to deliver healthy, crystal‑clear water for koi ponds up to 35,000 litres. Combining an automatic drum filter with a 250‑litre moving‑bed bio chamber, it provides powerful mechanical and biological filtration with minimal user intervention.

High‑Performance Drum Filter
The PF20 features a fully automated drum filter that continuously removes fine debris. As the screen becomes dirty, the float switch triggers a rinse cycle using a high‑pressure pump and spray bar. This ensures consistent water clarity without manual cleaning.

Large Moving‑Bed Bio Chamber
Behind the drum sits a 250L moving‑bed chamber, aerated via a dedicated air inlet. Once filled with approx. 100L of media, it provides exceptional biological filtration capacity, supporting stable water parameters even in heavily stocked koi ponds.

Flow Capacity & Connections
The PF20 is engineered for high flow rates, achieving 20 m³/h+ through its 110mm inlet and dual 110mm outlets. This makes it suitable for modern pump‑fed systems and high‑performance pond setups.

Safety & Reliability

• Designed for freshwater use
• Operates between 4–40°C
• Drum and control box must be installed in a dry, sheltered location
• Includes slip‑clutch protection on the drive shaft (65 Nm torque setting)

Maintenance
Routine maintenance is minimal—typically once per month. The drum can be rotated manually for inspection, and the screen panel can be replaced easily when worn.
