Fluidra - Diffuser Set for Aster Plus Deep Bed Sand Filter Ø750 mm 2"

Fluidra – Diffuser Set for Aster Plus Deep Bed Sand Filter Ø750 mm 2″

This is the genuine Fluidra replacement diffuser set designed for the Aster Plus Deep Bed 750 mm sand filter with a 2″ connection. The diffuser set sits inside the filter tank and is responsible for evenly distributing incoming water across the full surface of the filter media, as well as directing backwash flow to fully fluidise the sand bed during cleaning cycles. Replacing a worn or damaged diffuser set restores optimal filtration performance and backwash efficiency.

Compatibility

This diffuser set is a direct OEM replacement for the Fluidra Aster Plus Deep Bed sand filter with a 750 mm (Ø750) tank diameter and 2″ inlet/outlet connections. It is specifically engineered for the 1.2-metre deep bed variant of this filter. Always verify your filter model and connection size before ordering, as diffuser sets vary between tank diameters and bed depths.

Why Genuine Matters

Fluidra’s Aster-series diffusers are manufactured from injection-moulded, highly resistant PVC and polypropylene plastics, ensuring long service life in continuous pool water contact. A genuine OEM part guarantees correct dimensional fit and slot geometry, which is critical for even flow distribution across the filter bed and complete fluidisation during backwash — something off-brand alternatives frequently fail to deliver.

Installation

The diffuser set is accessed by removing the filter lid and lifting out the internal assembly. The components should be inspected for cracks or blocked slots before refitting. Professional installation is recommended for those unfamiliar with sand filter servicing, particularly to ensure all internal connections are correctly seated and watertight before returning the filter to service.
