AstralPool – Diffuser Assembly for Ultrabead 60-100-140 Filters (UB-60)

This is the genuine AstralPool replacement diffuser assembly for the Ultrabead 60, 100, and 140 sand filters (exploded view SK403). The diffuser sits at the top of the filter’s internal pipework and evenly distributes incoming pool water across the entire filter media bed, ensuring consistent filtration performance and effective backwashing on every cycle.

Compatibility

This diffuser assembly is designed exclusively for AstralPool Ultrabead 60-100-140 series filters, referenced under parts diagram SK403. It corresponds to position 13 in the official Fluidra exploded view. Always cross-reference your filter’s model and parts diagram before ordering to confirm fitment.

Why Genuine Matters

Using a genuine AstralPool diffuser assembly guarantees an exact dimensional match to the original component, preventing uneven flow distribution, media bypass, and premature wear. Aftermarket alternatives may not replicate the precise geometry required for optimal hydraulic performance in the Ultrabead filter body.

Installation

Replacement of the diffuser assembly typically requires draining the filter, removing the filter lid, and carefully extracting the internal pipe assembly. The diffuser locates into the central standpipe and should seat securely before the filter is refilled and recommissioned. Professional installation is recommended if you are unfamiliar with filter strip-downs.
