Fluidra - Sand Filter Diffuser Assembly Ø75 mm for Volcano Filter Ø1050–2000

Fluidra – Sand Filter Diffuser Assembly Ø75 mm for Volcano Filter Ø1050–2000

This is the genuine Fluidra replacement diffuser assembly for the Volcano sand filter range, covering tank diameters from Ø1050 mm to Ø2000 mm, with a 75 mm inlet connection. The diffuser is a critical internal component that receives incoming pool water from the multiport valve and distributes it evenly across the filter media bed, ensuring efficient filtration during normal operation and effective collection of dirty water during backwash cycles.

Compatibility

This diffuser assembly is designed specifically for the Fluidra Volcano sand filter series spanning tank diameters from Ø1050 mm to Ø2000 mm. It suits the 75 mm connection size variant of this filter range. Always verify your filter’s tank diameter and connection size against your existing diffuser before ordering, as Fluidra produces several diffuser assemblies for different diameter and connection combinations within the Volcano line.

Why Genuine Matters

The Volcano filter diffuser is made from chemically resistant, durable plastic engineered to withstand continuous immersion in chlorinated water and the mechanical stresses of repeated backwash cycles. A genuine Fluidra part guarantees exact dimensional fit, correct flow geometry, and long service life — third-party alternatives risk poor sealing, uneven water distribution, and premature failure that can compromise filtration quality for the entire pool system.

Installation

The diffuser assembly is accessed by opening the filter tank lid. The component typically locates onto the central standpipe or inlet fitting inside the tank and should be seated securely before the lid is refitted and the system is re-pressurised. Ensure the filter is fully depressurised and isolated from the pump before commencing any internal work. Professional installation is recommended for large commercial Volcano filter units.
