Fluidra - Sand Filter Diffuser Assembly Ø950 mm 2½"

Fluidra – Sand Filter Diffuser Assembly Ø950 mm 2½”

This is the genuine Fluidra replacement diffuser assembly for the AstralPool Aster laminated sand filter with a 950 mm tank diameter and 2½” connections. The diffuser is the internal component that distributes incoming water uniformly across the entire filter bed, ensuring efficient, even filtration throughout the sand media. Replacing a worn or damaged diffuser restores optimal flow distribution and protects filtration performance.

Compatibility

This diffuser assembly is designed specifically for the Fluidra AstralPool Aster sand filter range with a Ø900/950 mm tank body and 2½” pipe connections. It is not suitable for smaller Aster filter diameters (350–800 mm) or for other Fluidra filter series. Always verify your filter’s tank diameter and connection size before ordering.

Why Genuine Matters

As an OEM Fluidra part, this diffuser assembly is manufactured to the exact dimensions and material specification of the original — using highly resistant PVC and PP plastics engineered to withstand continuous pool water exposure and operating pressures up to 2.5 kg/cm². Aftermarket substitutes may differ in fit or material quality, risking channelling, bypass, or premature failure of the filter bed.

Installation

The diffuser assembly fits into the top of the filter tank and connects to the lateral collector arm system. Servicing requires draining the filter, removing the screwless lid, and lifting out the existing diffuser before fitting the replacement. While an experienced pool technician can complete the job efficiently, the task is achievable for a competent DIY installer who follows the Fluidra filter service documentation.
