AstralPool - Berlin Filter Diffuser Assembly Ø1050 mm / 75 mm - 4404010161

AstralPool – Berlin Filter Diffuser Assembly Ø1050 mm / 75 mm

This is the genuine AstralPool replacement diffuser assembly for the AstralPool Berlin sand filter with a 1050 mm diameter vessel and 75 mm connections. The diffuser is the internal plastic component that evenly distributes the incoming water flow across the filter media bed, ensuring consistent filtration performance and protecting media from channelling. It corresponds to position 13 in the official Fluidra exploded-view diagram for the Berlin Ø1050 mm filter range (parent catalogue ref 545).

Compatibility

This diffuser assembly is designed exclusively for the AstralPool Berlin bobbin-wound sand filter with a vessel diameter of 1050 mm and 75 mm pipework connections. Always cross-reference the exploded-view position (13) and parent catalogue reference (545) with your filter’s documentation before ordering, as Berlin filters are available in multiple diameters and connection sizes.

Why Genuine Matters

Manufactured from durable, chemically resistant plastics (PVC and PP) to AstralPool’s original tolerances, this OEM assembly seats correctly against the filter’s internal manifold without modification. Aftermarket alternatives may not match the exact profile of the 1050 mm vessel, risking bypass of unfiltered water and potential damage to downstream equipment. Using a genuine part also preserves any remaining manufacturer warranty on your filter system.

Installation

The diffuser assembly is accessed through the large 400 mm top manhole of the Ø1050 mm Berlin filter, making removal and refitting straightforward without dismantling the vessel. Depressurise and isolate the filter before beginning work. If you are not familiar with sand filter servicing, we recommend installation by a qualified pool technician.
