Fluidra - Diffuser Assembly Ø400 mm for Ivory Filter

Fluidra – Diffuser Assembly Ø400 mm for Ivory Filter

This genuine Fluidra diffuser assembly is an internal sand filter component designed specifically for the Fluidra Ivory Filter with a 400 mm tank diameter. Fitted inside the filter tank, it distributes incoming water evenly across the full surface of the filter bed, ensuring consistent filtration efficiency and preventing channelling through the sand media. Replacing a worn or damaged diffuser restores optimum flow distribution and protects overall filtration performance.

Compatibility

This diffuser assembly is engineered to fit the Fluidra Ivory Filter bobbin-wound sand filter with a Ø400 mm tank. Always verify your filter model and tank diameter before ordering, as diffuser assemblies are size-specific and will not interchange between different tank diameters. Refer to your filter’s original documentation or the Fluidra spare parts catalogue to confirm fitment.

Why genuine matters

As an OEM Fluidra part, this diffuser assembly is manufactured to the exact tolerances of the original component, guaranteeing a secure, leak-free fit within the tank and reliable long-term performance. Genuine parts also protect your filter’s warranty and give you confidence that the component has been tested to Fluidra’s quality standards — something aftermarket alternatives cannot guarantee.

Installation

The diffuser assembly is located inside the filter tank and is typically accessed by removing the multiport valve or top head. Installation requires draining the filter, removing the sand media, and securing the new diffuser in place before reassembling. While experienced pool technicians can complete this task on-site, professional installation is recommended to ensure correct seating and avoid damage to internal components.
