Fluidra - Diffuser Assembly for Ø900 mm Sand Filter

Fluidra – Diffuser Assembly for Ø900 mm Sand Filter

This is the genuine Fluidra replacement diffuser assembly designed for the Ø900 mm laminated sand filter rated at 30,000 l/h with a 2″ outlet (no multiport valve). The diffuser sits at the top of the filter tank and evenly distributes incoming water across the full surface of the filter bed, ensuring consistent, high-rate filtration throughout the media. Replacing a worn or cracked diffuser restores correct flow dynamics and protects filtration performance.

Compatibility

This diffuser assembly is a direct OEM replacement for Fluidra’s 30,000 l/h sand filter with an Ø900 mm tank and 2″ side outlet, supplied without a multiport selector valve. Always cross-reference your filter’s model number and the part SKU before ordering to confirm fitment — diffuser assemblies are tank-size specific and are not interchangeable across different diameter models.

Why Genuine Matters

As an original Fluidra spare part, this assembly is manufactured to the exact tolerances of the filter tank it was designed for. A correctly fitted diffuser prevents channelling through the sand bed, avoids short-circuiting of unfiltered water, and maintains the rated 30,000 l/h flow capacity. Third-party alternatives may not seat correctly, leading to poor water distribution or premature failure.

Installation

Installation requires opening the filter tank lid and removing the existing diffuser assembly. Ensure the filter is depressurised and isolated from the pump before starting work. Professional installation is recommended for commercial or high-flow systems to ensure correct seating and a watertight fit within the tank.
