Fluidra – Diffuser Assembly with Support Ø140 mm – Volcano 1800

This genuine Fluidra diffuser assembly with integrated support is a direct replacement internal component for the Volcano large-format sand filter range. The diffuser sits at the top of the filter tank and distributes incoming water evenly across the entire surface of the sand or glass media bed, ensuring consistent filtration performance. The included support bracket holds the diffuser precisely in position throughout operation.

Compatibility

This assembly is designed for the Fluidra Volcano sand filter series covering tank diameters from Ø1050 mm to Ø2000 mm, specifically the 1800 model variant. Always verify your filter’s model number and tank diameter before ordering to confirm fitment — Fluidra produces diffuser assemblies in several diameter sizes for this filter family.

Why Genuine Matters

As an OEM Fluidra part, this diffuser assembly is manufactured to the exact dimensional tolerances of the original component. An ill-fitting or aftermarket diffuser can channel water unevenly through the media bed, creating dead zones that allow unfiltered water to pass through. Using a genuine replacement preserves the hydraulic efficiency and flow rating your Volcano filter was designed to deliver.

Installation

Replacement typically requires draining the filter tank, removing the multiport valve or top flange, and lifting out the existing diffuser and support. The new assembly drops into the same mounting position. While the task is manageable for a competent DIYer, professional installation is recommended for large commercial-sized Volcano units to ensure correct reassembly and a leak-free seal.
