Fluidra - Diffuser Assembly for Ø600 mm Sand Filter

Fluidra – Diffuser Assembly for Ø600 mm Sand Filter

This is the genuine Fluidra replacement diffuser assembly designed for the Ø600 mm sand filter with a 1½” connection and a maximum flow rate of 14,000 l/h (without valve). The diffuser assembly sits at the top of the filter tank, distributing incoming water uniformly across the sand bed to ensure consistent, efficient filtration throughout the entire filter volume. Replacing a worn or damaged diffuser restores optimal water flow and filtration performance.

Compatibility

This diffuser assembly is a direct OEM spare part for the Fluidra Ø600 mm laminated sand filter (14,000 l/h, 1½” outlet, valve-free version), as found in the Aster and related Fluidra filter ranges. Always verify your filter’s model and diameter before ordering, as diffuser assemblies are size-specific and are not interchangeable between different tank diameters.

Why Genuine Matters

As an official Fluidra part, this diffuser assembly is manufactured to exact OEM tolerances, ensuring a precise fit and reliable long-term performance. Genuine parts maintain the structural integrity of the internal filter pipework and help avoid bypassing of unfiltered water — a common risk with non-OEM alternatives. Using genuine Fluidra spares also helps preserve any applicable product warranty.

Installation

The diffuser assembly is accessed by opening the filter lid. It typically clips or screws into the central standpipe at the top of the filter body. Installation is straightforward but requires draining the filter and disconnecting it from the pump circuit first. Professional installation is recommended if you are unfamiliar with sand filter internals, to ensure correct seating and leak-free reassembly.
