Fluidra - Diffuser Assembly for Artic Sand Filter Ø800 mm

Fluidra – Diffuser Assembly for Artic Sand Filter Ø800 mm

This is the genuine Fluidra replacement diffuser assembly designed specifically for the Artic laminated sand filter with an 800 mm tank diameter. Mounted internally at the top of the filter vessel, the diffuser evenly distributes incoming water across the entire surface of the filter bed during the filtration and rinse cycles, ensuring consistent flow and optimal filtration performance.

Compatibility

This diffuser assembly is a factory spare part for the Fluidra AstralPool Artic OC-1 sand filter range covering tank diameters of 500, 650, 800 and 950 mm — however, this specific part (SKU 4404010246) is matched to the Ø800 mm model. Always verify your filter’s diameter and model designation before ordering, as diffuser dimensions vary across the range.

Why Genuine Matters

An OEM Fluidra diffuser is precision-moulded to fit the exact internal geometry of the Artic filter vessel, maintaining the correct flow distribution that the filter was designed to deliver. A poorly fitting or non-genuine diffuser can cause channelling through the filter bed, sand carry-over into the pool, and uneven pressure build-up — all of which reduce water quality and can shorten the life of the filter media.

Installation

Before replacing the diffuser, isolate the pump, depressurise the filter system and remove the filter lid. Carefully unscrew and lift out the old diffuser, then seat the new assembly securely before refilling and restarting. It is good practice to cover the diffuser opening with the protective cap supplied during any filter media changes to prevent sand ingress into the internals.
