AstralPool – Diffuser Assembly BP.1050-63 for Viena Filter

This is the genuine AstralPool replacement diffuser assembly for the Viena Filter (SLX1050-20M), corresponding to position 19 in the official Fluidra exploded-view diagram. The diffuser sits centrally inside the filter tank and evenly distributes incoming water across the sand bed, ensuring consistent filtration performance and preventing channelling through the media.

How It Works

As water enters the filter, it passes through the diffuser — a perforated assembly that spreads the flow uniformly over the filtration media. This controlled distribution maximises contact between water and sand, delivering effective particle removal and maintaining clean, clear pool water. A damaged or degraded diffuser can cause uneven flow, reducing filtration efficiency and shortening media life.

Compatibility

This diffuser assembly is designed exclusively for the AstralPool Viena Filter with a 1,050 mm tank diameter and 63 mm pipework connections (model SLX1050-20M). Always verify your filter model and exploded-view position (19) before ordering to ensure a correct fit. It is not interchangeable with diffuser assemblies from other diameter or pipe-size variants in the BP series.

Why Genuine Matters

As an original AstralPool spare part manufactured to Fluidra’s exact tolerances, this assembly ensures a precise fit within the filter body without modification. Genuine parts maintain your filter’s rated working pressure and flow specifications, protecting your warranty and giving you confidence in long-term reliability.
