Fluidra - Sand Filter Diffuser Assembly Ø800 mm (BWS2)

Fluidra – Sand Filter Diffuser Assembly Ø800 mm (BWS2)

This is the genuine Fluidra replacement diffuser assembly for the Ø800 mm tank variant of the BWS2 bobbin-wound fibreglass sand filter series. The diffuser sits at the top of the internal lateral system and distributes incoming pool water evenly across the sand bed, ensuring consistent filtration velocity and preventing channelling. Replacing a worn or cracked diffuser restores full filtration performance and protects the sand bed from bypass flow.

Compatibilità

This diffuser assembly is designed specifically for the Fluidra AstralPool BWS2 750–800–900 filter series, fitting the Ø800 mm tank model. The BWS2 range is a residential and semi-commercial side-outlet sand filter manufactured from polyester resin and fibreglass, rated to a maximum operating pressure of 2.5 bar with a 2″ side connection. Always confirm your tank diameter and model code before ordering to ensure correct fitment.

Perché l'autenticità è importante

A genuine Fluidra diffuser assembly is precision-moulded to match the exact internal geometry of the BWS2 tank, guaranteeing a flush, leak-free seat against the lateral manifold. Aftermarket alternatives may differ subtly in diameter or port sizing, leading to poor water distribution, reduced filtration efficiency, or premature failure. Sourcing direct from the Fluidra spare parts range ensures full traceability and manufacturer warranty alignment.

Installazione

Installation requires draining the filter tank and removing the sand media to access the internal lateral assembly. The diffuser assembly locates onto the central standpipe at the top of the lateral collector and should be checked for cracks or warping before refitting. Refer to the BWS2 filter’s official Fluidra installation manual for torque values and sand-refill procedures; professional installation is recommended for first-time servicing of this filter size.
