Fluidra – Collector Arm Assembly for Ø650 mm Sand Filter

Fluidra – Collector Arm Assembly for Ø650 mm Sand Filter

This is the genuine Fluidra collector arm assembly designed for the Red Astral DV-650 laminated sand filter (Ø650 mm tank). The assembly sits at the base of the filter vessel and is responsible for collecting filtered water through its slotted lateral arms and redistributing flow evenly across the sand bed during backwash cycles.

How It Works

The collector arm assembly connects to a central hub at the bottom of the filter tank. The slotted lateral arms spread radially through the sand, drawing filtered water uniformly toward the outlet during normal filtration and ensuring thorough, even fluidisation of the entire filter bed during backwash — a critical function for maintaining filtration efficiency.

Compatibility

This assembly is specifically sized and engineered for the Fluidra Red Astral DV-650 sand filter with a Ø650 mm tank diameter. Always verify your filter model and tank diameter before ordering, as collector arm assemblies are not interchangeable between different tank sizes.

Why Genuine Matters

Genuine Fluidra spare parts are manufactured to exact OEM tolerances, ensuring a precise fit and reliable long-term performance. Third-party alternatives may not match the arm length, slot dimensions, or hub coupling of your filter, risking sand bypass, uneven filtration, or premature failure.
