Fluidra - Diffuser Assembly for Artic Plus Sand Filter Ø650 mm

Fluidra – Diffuser Assembly for Artic Plus Sand Filter Ø650 mm

This is the genuine Fluidra replacement diffuser assembly designed specifically for the Artic Plus laminated sand filter with a 650 mm tank diameter and 1½” connections. The diffuser sits at the top of the filter tank and evenly distributes incoming pool water across the filtration bed, ensuring consistent flow and maximum filtration efficiency. Replacing a worn or damaged diffuser restores correct water circulation and protects filter performance.

Compatibility

This diffuser assembly is a direct OEM replacement for the Fluidra Artic Plus sand filter, Ø650 mm, fitted with 1½” ACME threaded connections and a collector arms system. Always verify your filter’s diameter and connection size before ordering, as Artic Plus filters are available in multiple sizes (650, 800, and 950 mm), each requiring its own specific diffuser assembly.

Why Genuine Matters

As an original Fluidra spare part, this assembly is manufactured to the exact tolerances of the Artic Plus filter, ensuring a perfect seal and fit within the polyester-fibreglass tank rated to a maximum working pressure of 2.5 bar. Generic alternatives may not match the precise dimensions required, risking leaks, bypass flow, and reduced filtration quality. A genuine part also keeps your warranty intact.

Installation

The diffuser assembly is accessed through the filter lid after releasing pressure and draining the tank. Carefully remove the existing diffuser, inspect the mating surfaces for debris or damage, then seat the new assembly securely before refitting the lid. While experienced pool technicians will find this a straightforward job, owners less familiar with pressurised filter systems should seek professional assistance to ensure a safe, leak-free installation.
