AstralPool – Diffuser Assembly for Delta Filter 1000–1200 (Ø 1200 mm)

This is a genuine AstralPool replacement diffuser assembly (position 26 in the official Fluidra exploded view) designed specifically for the AstralPool Delta Filter 1000–1200 series with a 1200 mm vessel diameter. The diffuser sits at the core of the filter’s internal hydraulics, evenly distributing the incoming water flow across the sand bed to ensure consistent filtration performance. Keeping this component in good condition is essential for maintaining efficient backwash cycles and maximising filter media life.

Compatibility

This diffuser assembly is a direct-fit spare part for the AstralPool Delta Filter 1000–1200 D.1000–1200 (parent SKU 36683), which is a polyester and fibreglass laminated sand filter available in diameters from 650 mm to 1200 mm and rated to a maximum working pressure of 2.5 bar. It corresponds to position 26 in the official Fluidra exploded view diagram for this filter series. Always verify your filter’s model number and vessel diameter before ordering to confirm fitment.

Why Genuine Matters

Sourcing a genuine AstralPool diffuser assembly ensures precise dimensional tolerances and material compatibility with the filter’s internal PVC, PP, and ABS pipework and fittings. Non-OEM alternatives risk poor seating, uneven flow distribution, and premature wear — particularly in the high-capacity, commercial-grade environments for which the Delta Filter series is designed. A correctly fitted genuine part helps the filter comply with the EN 16713-1 filtration standard.

Installation

Replacement of the diffuser assembly requires draining the filter vessel and removing the top lid before accessing the internal components. Professional installation is recommended, especially on large commercial filter tanks where working pressures and flow rates are substantial. Always consult the official Fluidra exploded view (position 26) and the filter’s service manual during reassembly to ensure all internal components are correctly seated and sealed.
