Fluidra - Manifold Assembly for BWS2 Sand Filter Ø800 mm

Fluidra – Manifold Assembly for BWS2 Sand Filter Ø800 mm

This is the genuine Fluidra manifold assembly designed for the AstralPool BWS2 sand filter with an 800 mm tank diameter. The manifold is the internal collector system that sits at the base of the filter vessel, gathering filtered water through its slotted lateral arms and directing it out of the tank during filtration, while also evenly distributing water across the sand bed during backwash cycles. Replacing a cracked or damaged manifold restores full filtration efficiency and prevents sand from passing through to the pool.

Compatibility

This manifold assembly is a direct factory replacement part for the Fluidra AstralPool BWS2 filter series in the 750–800–900 mm diameter range, specifically sized for the Ø800 mm tank variant. Always confirm the tank diameter and filter model code on your unit’s label before ordering, as manifold assemblies are size-specific and are not interchangeable between different diameter tanks.

Why Genuine Matters

As a genuine Fluidra OEM part, this manifold assembly is manufactured to the exact tolerances and slot dimensions of the original component, ensuring correct flow distribution and a secure fit within the filter body. Aftermarket alternatives may feature incorrect slot widths that allow sand to bypass into the pool, or poor sealing at the central hub that leads to channelling through the filter bed. Using a genuine part protects your filtration performance and your Fluidra warranty.

Installation

Installation requires draining and opening the filter tank. Before adding new filter media, carefully seat the manifold assembly centrally and verify that all lateral arms are correctly positioned and undamaged. Fill the tank with approximately one-third water to cushion the media before pouring it in, taking care not to strike the manifold during filling. If you are not comfortable working inside a pressurised filter vessel, we recommend having the job carried out by a qualified pool technician.
