Fluidra – Diffuser Assembly for Ø900 mm Sand Filter 2″ Outlet

This is the genuine Fluidra replacement diffuser assembly designed for the AstralPool Aster laminated sand filter with a Ø900 mm tank and 2″ side outlet, rated at 30,000 l/h. The diffuser sits at the top of the filter tank and evenly distributes incoming pool water across the surface of the sand bed, ensuring consistent, efficient filtration throughout the media. Replacing a worn or damaged diffuser restores proper flow distribution and protects overall filter performance.

Compatibility

This diffuser assembly is a direct fit for the Fluidra AstralPool Aster laminated sand filter with a Ø900 mm diameter tank and 2″ side outlet connections, in the without-multiport-valve configuration. Always verify your filter’s tank diameter and outlet size before ordering. If you are unsure, compare the part number against your filter’s exploded-view diagram in the original documentation.

Why genuine matters

Genuine Fluidra parts are manufactured to the exact tolerances of the original equipment, ensuring a secure, leak-free fit within the filter body. Third-party diffusers may not match the precise dimensions needed for the Ø900 mm tank, risking bypass of unfiltered water and premature wear. Sourcing an authentic Fluidra part also keeps your filter’s warranty and service record intact.

Installation

Installation involves draining and opening the filter tank, removing the old diffuser, and seating the new assembly centrally above the lateral manifold collector. The Aster range features a screwless lid system for straightforward access. While the process is manageable for a competent pool owner, a qualified pool technician is recommended for first-time servicing of large-format commercial-grade filters.
