Fluidra - Manifold Arm Assembly for Volcano Sand Filter Ø1800 mm

Fluidra – Manifold Arm Assembly for Volcano Sand Filter Ø1800 mm

This is a genuine Fluidra manifold arm assembly designed specifically for the Ø1800 mm tank variant of the Fluidra Volcano sand filter range (D. 1050 to 2000). The manifold is the central internal collector system — a hub with radiating lateral arms — that sits at the base of the filter tank, collecting water that has passed through the sand bed and directing it cleanly to the filter outlet. Replacing a worn, cracked or broken manifold assembly restores proper filtration efficiency and prevents unfiltered water or sand from bypassing the filter media.

Compatibility

This manifold arm assembly is sized for the Ø1800 mm diameter tank in the Fluidra Volcano Filter series (D. 1050 to 2000). The Volcano range covers large commercial and semi-commercial swimming pool installations. Always verify your filter’s tank diameter and model reference before ordering, as Fluidra offers different manifold assemblies for each tank diameter within this series — an incorrectly sized manifold will not seal or function correctly.

Why Genuine Matters

As an OEM Fluidra spare part, this assembly is manufactured to the exact dimensional tolerances of the original, ensuring a precise fit with the filter’s central standpipe and tank base. Genuine parts maintain the structural integrity of the manifold under the pressures of high-flow commercial filtration, avoiding the leaks, sand bypass or pressure loss that can result from ill-fitting aftermarket alternatives.

Installation

The manifold arm assembly is accessed by removing the filter’s multiport or top-mount valve and lifting out the internal assembly. Given the large tank diameter and the volume of filter media involved, draining the tank and removing the sand is required before replacement. Professional installation by a qualified pool technician is strongly recommended for filters of this size and capacity.
