AstralPool - Filter Diffuser Assembly Ø1050 – 90 mm - SP-04-0321

AstralPool – filter diffuser assembly Ø1050 – 90 mm

This is a genuine AstralPool replacement diffuser assembly designed for AstralPool sand and media filtration tanks in the 1050 mm diameter range with a 90 mm lateral/diffuser connection. The diffuser assembly sits inside the filter tank and distributes water evenly across the filter media bed, ensuring efficient filtration and consistent flow throughout the system.

Replacing a worn or cracked diffuser restores proper water distribution, prevents channelling through the filter media, and maintains the hydraulic performance your pool system depends on.

Compatibility

This diffuser assembly is engineered for AstralPool filter tanks with a 1,050 mm tank diameter and 90 mm diffuser fitting, including models in the Volcano and BP filter ranges rated at 2.5 kg/cm² working pressure. Always verify your filter’s model number and tank diameter before ordering to ensure a correct fit. Consult the AstralPool parts diagram for your specific filter model if in doubt.

Why genuine matters

As a genuine AstralPool part, this diffuser assembly is manufactured to the exact tolerances required for a leak-free, secure fit within the filter tank. Aftermarket alternatives may not seal correctly, leading to bypassed unfiltered water, reduced flow rates, or damage to other filter internals. Using genuine parts also keeps your equipment warranty valid.

Installation

Installation involves opening the filter tank, removing the multiport valve or top fitting, and replacing the diffuser assembly onto the lateral hub. While many experienced pool technicians can complete this as a straightforward servicing task, it is recommended that the filter be fully depressurised and isolated before work begins. If you are unsure, professional installation is advised.
