AstralPool – Diffuser Assembly for Vic Filter Ø1200 75mm (Pre-June 2019)

This is the genuine AstralPool diffuser assembly designed specifically for the Vic Filter Ø1200 with 75 mm outlets (model 11512N), manufactured before June 2019. The diffuser sits at the top of the internal distribution system and is responsible for evenly spreading incoming water across the sand bed, maximising filtration performance and protecting the filter media during backwash cycles. It corresponds to position 17 in the official Fluidra exploded-view diagram.

Compatibility

This assembly is an exact-fit replacement part for the AstralPool Vic Filter Ø1200, 1½” connections, 1.0 m bed depth, 2.5 kg/cm² working pressure (parent model 11512N), units produced prior to June 2019 only. AstralPool updated the internal geometry of the Vic Filter range in mid-2019; if your filter was manufactured from June 2019 onwards, this part will not be correct — always check your filter’s production date and the official Fluidra exploded-view diagram before ordering.

Why Genuine Matters

An OEM diffuser assembly ensures precise dimensional fit with the Vic Filter’s collector tube and tank internals. Aftermarket or incorrectly sized diffusers can cause uneven water distribution, channelling through the sand bed, and premature filter media contamination. Using a genuine AstralPool part maintains the rated filtration efficiency and keeps your filter within manufacturer warranty terms.

Installation

The diffuser assembly locates directly onto the central collector tube inside the filter vessel. Fitting should be carried out by a qualified pool technician with the system fully depressurised and isolated. Refer to position 17 of the official Fluidra exploded-view diagram for the correct orientation and torque guidance before reassembling the filter lid and returning the system to service.
