Fluidra - Sand Filter Diffuser Assembly Ø900 mm 2½" Female Thread

Fluidra – Sand Filter Diffuser Assembly Ø900 mm 2½” Female Thread

This is the genuine Fluidra replacement diffuser assembly for Ø900 mm commercial sand filters with a 2½” female-threaded inlet connection. The diffuser sits at the top of the filter tank and distributes incoming water evenly across the entire surface of the sand bed, ensuring consistent, high-quality filtration at flow rates up to 31,000 l/h. It is an essential internal component for maintaining optimal filter performance.

Compatibility

This diffuser assembly is designed specifically for the Fluidra Ø900 mm sand filter rated at 31,000 l/h with a 2½” outlet and no multiport valve (valve-free configuration). Always verify your filter’s tank diameter, flow rating, and connection size before ordering, as diffuser assemblies are model-specific and not interchangeable across different tank sizes.

Why Genuine Matters

Using a genuine Fluidra diffuser assembly guarantees a precise fit within the Ø900 mm tank, correct thread engagement on the 2½” female connection, and materials engineered to withstand continuous pool water chemistry and pressure. Aftermarket alternatives may cause uneven water distribution, channelling through the sand bed, or premature failure — all of which compromise filtration efficiency and water quality.

Installation

The diffuser assembly is installed inside the top of the filter tank, threading onto the 2½” female inlet port. Access requires opening the filter lid and removing any existing diffuser. Professional installation is recommended for commercial-scale equipment of this size to ensure correct seating, leak-free connection, and safe recommissioning of the filtration system.
