This is the genuine AstralPool replacement diffuser assembly, designed specifically for the Hawaii Filter D. 750-900 series (parent reference BWS750). The diffuser sits inside the filter tank and evenly distributes incoming water across the sand bed, ensuring consistent, efficient filtration on every cycle. It corresponds to position 15 in the official Fluidra exploded-view diagram for this filter family.<\/p>\n
This diffuser assembly is engineered exclusively for the AstralPool Hawaii Filter D. 750-900 range (BWS750). It is not interchangeable with other filter families or diameter variants \u2014 always verify your filter’s model reference before ordering to guarantee a correct fit.<\/p>\n
The diffuser channels water entering the filter from the multiport valve and spreads it uniformly across the full filtration surface. Manufactured from highly resistant PVC and polypropylene plastic, it withstands continuous exposure to pool water, chemicals, and operating pressures up to 2.5 kg\/cm\u00b2.<\/p>\n
An OEM diffuser ensures the precise flow geometry required for optimal sand-bed utilisation and backwash performance. Aftermarket alternatives may cause channelling, reduced filtration quality, or poor backwash efficiency. Sourcing directly from AstralPool’s Fluidra parts catalogue guarantees dimensional accuracy and material compatibility.<\/p>\n
