This is the genuine Fluidra (AstralPool) replacement manifold collector arm assembly \u2014 a complete set of 12 slotted lateral arms \u2014 designed for large-diameter sand filters with tank diameters of \u00d8950 mm and \u00d81050 mm. The collector arms sit at the base of the filter tank, gathering filtered water from beneath the sand bed and channelling it back to the pool, while also lifting and agitating the filter media during backwash to flush retained debris out of the system.<\/p>\n
This assembly is compatible with a wide range of Fluidra and AstralPool large-format sand filters, including the Berlin side-outlet filter \u00d8900 mm, the lateral UVE filter \u00d8950 mm, the Aster lateral filter \u00d8900 mm, and the Vesuvius\/Volcano series from \u00d81050 mm upwards. It may also fit other filters of the same brand in the \u00d8950\u20131050 mm diameter range \u2014 always cross-reference your filter’s model number and exploded-view diagram before ordering.<\/p>\n
Damaged or cracked collector arms are a leading cause of sand passing through to the pool \u2014 a tell-tale sign being sand deposits near the pool’s water return inlets. Using a genuine Fluidra part ensures the slotted openings are precision-manufactured to the correct calibre, maintaining proper filtration efficiency and preventing media bypass. Genuine parts also carry the manufacturer’s warranty and are made from chemically resistant materials suited to continuous contact with pool water and backwash pressure.<\/p>\n
Replacing the full set of 12 arms at once is recommended, as individual arms tend to degrade at a similar rate. The tank must be fully drained and the filter media removed before access to the manifold is possible. Professional installation is advisable for large commercial filters of this size; always consult the relevant Fluidra exploded-view diagram (available on the Fluidra spare parts catalogue) to confirm the correct assembly orientation.<\/p>","protected":false},"excerpt":{"rendered":"
