AstralPool - Sand Filter Diffuser Assembly D. 400 - SP-04-0245

AstralPool – sand filter diffuser assembly D. 400

This is a genuine AstralPool replacement diffuser assembly designed for AstralPool sand filters with a 400 mm (D. 400) tank diameter. The diffuser sits at the top of the filter’s internal distribution system, evenly spreading incoming water across the filter media bed to ensure uniform filtration and efficient backwashing. Replacing a worn or cracked diffuser restores proper flow distribution and maintains peak filtration performance.

Compatibilitate

This diffuser assembly is compatible with AstralPool sand filters of 400 mm vessel diameter. Always verify your filter’s tank diameter and internal configuration before ordering. If in doubt, cross-reference the part number with your filter’s exploded parts diagram or consult a qualified pool technician.

De ce autenticitatea contează

Made from UV-stable, chemical-resistant plastic (PVC/polypropylene) that is unaffected by salt water and pool chemicals, this OEM part is engineered to the exact dimensions of the original, ensuring a precise fit and a reliable pressure-rated seal. Non-genuine substitutes may differ in geometry or material grade, compromising filtration efficiency and potentially voiding your filter warranty.

Instalare

Installation requires opening the filter tank and removing the existing diffuser from the central standpipe. Ensure the filter is fully depressurised and the multiport valve is set to the closed or winterise position before servicing. Professional installation is recommended if you are unfamiliar with sand filter internals.
