AstralPool – Diffuser Assembly for Aster Sand Filter Ø650 mm

This is the genuine AstralPool replacement diffuser assembly for the Aster laminated sand filter with a 650 mm diameter (parent SKU 21071). The diffuser is a key internal component that evenly distributes incoming water across the filter’s sand bed, ensuring thorough filtration on the downstroke and effective backwashing on the reverse cycle. It is manufactured from durable, chemically resistant PVC and polypropylene (PP) plastics to withstand continuous pool water exposure.

Kompatybilność

This diffuser assembly is designed exclusively for the AstralPool Aster sand filter range with a 650 mm body diameter, referenced under parent SKU 21071. It corresponds to position 15 in the official Fluidra/AstralPool exploded parts diagram for the Aster filter series. Always verify your filter’s diameter and model code before ordering to ensure a precise fit.

Dlaczego oryginalność ma znaczenie

Using an original AstralPool diffuser assembly guarantees dimensional accuracy and material compatibility with the Aster filter body. The Aster filter is rated for a maximum filtration speed of 50 m³/h/m² and a maximum working pressure of 2.5 kg/cm²; an ill-fitting or substandard diffuser can compromise these performance parameters and lead to channelling, poor water clarity, or premature wear. A genuine part maintains your filter’s compliance with EN 16713-1 filtration standards.

Instalacja

The diffuser assembly is accessed by removing the Aster filter’s quick-release, screwless lid — no special tools are required to open the vessel. Once inside, the worn or damaged diffuser can be lifted out and the new assembly seated in its place. We recommend draining the filter, rinsing the interior, and inspecting the surrounding collector arms and O-rings while the filter is open. If you are not confident working with pressurised pool filtration equipment, consult a qualified pool technician.
