Fluidra - Sand Filter Diffuser Assembly Ø800 mm

Fluidra – Sand Filter Diffuser Assembly Ø800 mm

This is the genuine Fluidra replacement diffuser assembly designed for the Ø800 mm laminated sand filter with bayonet valve connection (24,000 l/h, 2″ outlets). The diffuser sits at the top of the internal distribution system and spreads incoming pool water evenly across the full surface of the sand bed, ensuring consistent filtration performance and preventing channelling through the filter media.

Compatibility

This diffuser assembly is specifically sized for the Fluidra/AstralPool Ø800 mm laminated sand filter rated at 24,000 l/h with a 2″ bayonet valve. Always verify your filter’s tank diameter and model before ordering, as diffuser assemblies are not interchangeable between different tank sizes. Check your filter’s documentation or the spare parts diagram on the Fluidra website if in doubt.

Why Genuine Matters

Made from highly resistant PVC and polypropylene plastic, the genuine Fluidra diffuser assembly is engineered to withstand continuous exposure to pool water, chlorine, and operating pressures up to 2.5 kg/cm². An incorrect or worn diffuser can cause uneven water distribution, reduce filtration efficiency, and lead to sand bypass into the pool — making like-for-like replacement with a genuine OEM part essential.

Installation

Replacement of the diffuser assembly requires draining the filter tank and removing the sand media to access the internal distribution system. The pump must be switched off and the system depressurised before opening the filter. Reassembly should follow the filter’s original installation manual; professional installation is recommended if you are not familiar with sand filter internals.
