Fluidra - Diffuser Assembly for Volcano Sand Filter Ø1200 mm

Fluidra – Diffuser Assembly for Volcano Sand Filter Ø1200 mm

This is the genuine Fluidra diffuser assembly designed specifically for the Volcano sand filter with a 1,200 mm tank diameter. The diffuser sits inside the filter tank and evenly distributes incoming water across the full surface of the sand bed, ensuring consistent filtration performance and preventing channelling. It is an essential internal component for maintaining the filter’s rated flow capacity and water clarity.

Compatibility

This diffuser assembly is engineered exclusively for the Fluidra Volcano Filter range with tank diameters of 1,050 to 1,200 mm. The Ø1200 mm Volcano filter is rated for flow rates up to 56 m³/h and is used in both large residential and commercial pool installations. Always verify your filter’s tank diameter before ordering, as diffuser assemblies are size-specific and are not interchangeable between different tank models.

Why Genuine Matters

Using a genuine Fluidra replacement part guarantees dimensional accuracy and material compatibility with your existing filter internals. A correctly fitted diffuser assembly maintains even water distribution across the sand bed, which is critical for achieving efficient filtration and avoiding premature media channelling. Aftermarket alternatives may not match the precise geometry required by the Volcano filter tank, risking reduced performance or seal failures.

Installation

The diffuser assembly is accessed by removing the filter’s top cover or multiport valve. Fitting requires no specialist tools, but working inside a large commercial-grade filter tank of this size is best carried out by a qualified pool technician. Ensure the filter is fully depressurised and isolated from the circulation system before beginning any internal work.
