Fluidra - Diffuser Assembly for Artic Plus Sand Filter Ø950 mm, 2½"

Fluidra – Diffuser Assembly for Artic Plus Sand Filter Ø950 mm, 2½”

This genuine Fluidra diffuser assembly is the OEM replacement part for the Artic Plus laminated sand filter with a 950 mm tank diameter and 2½” pipework connections. The diffuser sits at the top of the filter’s internal manifold system, directing incoming water evenly down through the filter bed to ensure consistent, high-performance filtration. Replacing a cracked or worn diffuser restores proper water distribution and prevents channelling through the filter media.

Compatibility

This assembly is designed exclusively for the Fluidra Artic Plus sand filter range in the Ø650–800–950 mm diameter group with 2½” ACME threaded connections. The Artic Plus is a fibreglass-reinforced polyester laminated filter rated to a maximum working pressure of 2.5 bar, featuring a 1.2 m filtration bed height and a PP collector arms system with 0.3 mm slots. Always verify your filter’s tank diameter and connection size before ordering, as diffuser assemblies are not interchangeable across different tank sizes.

Why genuine matters

As an original Fluidra spare part, this diffuser assembly is manufactured to the exact tolerances of the Artic Plus filter internals, ensuring a secure, leak-free fit against the manifold and tank body. Generic alternatives risk poor sealing and uneven flow distribution, which can lead to turbid water and premature wear on other filter components. Choosing a genuine part protects the overall integrity and rated performance of your Artic Plus filter installation.

Installation

Before fitting, isolate the pump and depressurise the filter system fully. Remove the filter lid, carefully extract the existing diffuser, and inspect the manifold arms and collector strainers for damage at the same time. Seat the new diffuser assembly securely before adding or redistributing filter media, then replace the lid and repressurise slowly, checking for leaks. Professional installation is recommended if you are unfamiliar with pressurised filter systems.
