AstralPool – Diffuser Assembly for Vic Filter Ø1800 110mm

This is the genuine AstralPool replacement diffuser assembly (position 17 in the official Fluidra exploded view) designed specifically for the AstralPool Vic Filter Ø1800 with 110 mm outlets (parent SKU 11520N). The diffuser sits at the inlet of the filter tank and distributes incoming pool water evenly across the sand bed, ensuring consistent filtration performance and protecting the filter media from channelling or displacement.

How It Works

When pool water enters the filter, the diffuser assembly spreads the flow uniformly over the full cross-section of the sand bed. This even distribution maximises contact time between the water and the filter media, improving filtration efficiency. An increased freeboard between the top sand layer and the diffuser head further promotes even water distribution during filtration and helps prevent sand from being drawn into the lateral arms during backwashing.

Compatibility

This diffuser assembly is engineered exclusively for the AstralPool Vic Filter Ø1800 with 1½” collector arms and 110 mm outlets, referenced under parent SKU 11520N. The Vic Filter is an industrial-grade bobbin-wound sand filter rated at 76 m³/h and a maximum working pressure of 2.5 bar. Always verify your filter’s model number and exploded-view position before ordering to ensure correct fitment.

Why Genuine Matters

Manufactured from robust PVC and polypropylene, this OEM part meets AstralPool’s original material and dimensional specifications, ensuring a precise fit and long service life. Non-genuine alternatives may differ in wall thickness or connection dimensions, risking leaks, uneven flow distribution, or premature failure. Fitting an authentic AstralPool diffuser assembly keeps your filtration system operating at its designed flow rate and pressure rating.
