Fluidra - Collector Arm Assembly 3/4" for Aster Sand Filter Ø750 mm

Fluidra – Collector Arm Assembly 3/4″ for Aster Sand Filter Ø750 mm

This is the genuine Fluidra replacement collector arm assembly for the Aster sand filter with a Ø750 mm tank and 2″ top-mount multiport valve. The collector arm assembly is the internal lateral manifold system that sits at the base of the filter tank, collecting filtered water and distributing flow evenly during backwash to fully fluidise the sand bed.

How It Works

The collector arms extend radially from a central hub inside the filter vessel. During normal filtration, water passes down through the sand media and is gathered by the slotted laterals before returning to the pool. During backwash, flow is reversed through the same arms, lifting and cleaning the sand bed uniformly across the full tank diameter.

Compatibility

This assembly is designed specifically for the Fluidra Aster sand filter with a Ø750 mm tank, rated at 21,000 l/h, fitted with a 2″ top-mount multiport valve. Always verify your filter model and tank diameter before ordering — this part is not interchangeable with smaller Aster tank sizes (e.g. Ø600 mm or Ø650 mm).

Why Genuine Matters

As a genuine Fluidra spare part, this collector arm assembly is manufactured to the exact tolerances of the original component, ensuring a correct fit, reliable sealing between arms and hub, and long service life. Aftermarket substitutes may differ in slot size or arm length, compromising filtration efficiency and backwash performance.
