Fluidra - Diffuser Assembly Ø75 mm for Volcano Sand Filter Ø1400 mm

Fluidra – Diffuser Assembly Ø75 mm for Volcano Sand Filter Ø1400 mm

This genuine Fluidra diffuser assembly is the factory-correct replacement for the Volcano large-format sand filter with a Ø1400 mm tank body, fitted with a Ø75 mm diffuser connection. The diffuser assembly sits at the base of the filter vessel and evenly distributes water across the full cross-section of the sand bed, ensuring optimal filtration efficiency and balanced flow. Replacing a worn or cracked diffuser restores proper hydraulic balance and protects filter media from channelling.

Compatibility

This diffuser assembly is designed specifically for the Fluidra Volcano sand filter range covering tank diameters from Ø1050 mm to Ø2000 mm, and is sized for the Ø1400 mm tank variant with a Ø75 mm outlet connection. Always verify your filter’s tank diameter and diffuser connection size against the part markings before ordering, as diffuser assemblies are not interchangeable across different tank sizes within the Volcano range.

Why Genuine Matters

As an OEM Fluidra spare part, this diffuser assembly is manufactured to the exact dimensional and material tolerances of the original component, guaranteeing a leak-free fit and long service life. Aftermarket alternatives may differ in geometry, leading to uneven water distribution, sand bypass, or premature failure — risks that are eliminated by specifying the genuine article.

Installation

Installation requires draining the filter tank and removing the lateral manifold assembly to access the diffuser at the base. Due to the size of the Volcano filter range, this work is best carried out by a qualified pool technician. Ensure all sealing surfaces are clean and inspect adjacent laterals and the central standpipe for wear before reassembly.
