Pro-Line Aqua Expert Combi 50 – High-Performance Filter Body for Large Ponds

The Pro-Line Aqua Expert Combi 50 is a professional-grade filter body designed to support efficient, reliable filtration in large or heavily stocked ponds. Ideal for use in high-bio-load koi ponds, commercial pond systems, and swimming ponds, this filter body delivers robust performance and low-maintenance operation.

Built from 12mm thick, high-quality materials, the Combi 50 is engineered for durability. It features a strong extrusion weld at the base—a superior design choice that offers increased strength over standard welded filters. This makes it ideal for supporting Combi filters with moving-bed chambers or drum filtration setups.

With a compact footprint and flow capacity of up to 50 m³/h, it provides maximum filtration efficiency while saving space. The control box can be mounted up to 4 metres away, offering flexible installation options, and can be extended with additional cables if required.

Its 24V gear-driven system is safe for use in swimming ponds and features no underwater shafts, reducing the risk of leaks and water ingress. The high-spec control unit ensures smooth, intuitive operation.
