Fluidra - Diffuser Assembly for Volcano Sand Filter Ø1800 mm / 110 mm Outlet

Fluidra – Diffuser Assembly for Volcano Sand Filter Ø1800 mm / 110 mm Outlet

This is the genuine Fluidra diffuser assembly designed specifically for the Volcano large-format sand filter with an Ø1800 mm tank and 110 mm pipe connections. The diffuser distributes incoming water evenly across the entire filter bed, ensuring consistent filtration performance and preventing channelling through the sand media. It is a direct OEM replacement that restores your filter to its original operating specification.

Compatibility

This diffuser assembly is engineered exclusively for the Fluidra Volcano sand filter series with an Ø1800 mm tank diameter and 110 mm outlet connections. The Volcano range is a heavy-duty, large-capacity filter typically found in public, commercial, and large residential pool installations. Always verify your filter’s tank diameter and outlet size against the part specifications before ordering.

Why Genuine Matters

As an OEM Fluidra spare part, this diffuser assembly is manufactured to the exact tolerances of the original component. A correctly fitting diffuser prevents bypass of unfiltered water, protects the sand bed from erosion, and avoids pressure imbalances that can accelerate wear on other internal components. Aftermarket alternatives may not seal or seat correctly in this large-format filter body.

Installation

Installation should be carried out with the filter fully depressurised and isolated from the pump circuit. The diffuser assembly locates centrally within the filter tank and must be seated securely before the tank is closed and returned to service. Professional installation is recommended for commercial-scale equipment of this size.
