Fluidra - Collector Assembly for Ø750 mm Sand Filter

Fluidra – Collector Assembly for Ø750 mm Sand Filter

This is the genuine Fluidra replacement collector assembly designed for the Ø750 mm side-outlet sand filter with 2″ bayonet valve and a rated flow of 21,000 l/h. Positioned at the base of the filter tank, the collector assembly — comprising a central hub and slotted lateral arms — gathers filtered water evenly across the full tank floor and channels it out through the outlet. It also plays a critical role during backwash, ensuring complete and uniform fluidisation of the sand bed.

Compatibility

This collector assembly is a direct OEM replacement for the Fluidra/AstralPool Ø750 mm (D750) side-outlet sand filter fitted with a 2″ bayonet-closure multiport valve. Always verify your filter’s diameter and model reference before ordering, as collector assemblies are not interchangeable between different tank sizes.

Why Genuine Matters

Genuine Fluidra parts are manufactured to the exact dimensional tolerances of the original filter tank, guaranteeing a precise fit with no gaps or bypasses that could allow unfiltered water to pass through. Off-brand laterals can crack under repeated backwash pressure cycles, sending sand into the pool; genuine Fluidra polypropylene construction resists chemical attack and physical stress over years of continuous use.

Installation

Replacing the collector assembly requires draining and opening the filter tank, removing the old hub-and-lateral unit, and seating the new assembly firmly before refilling with filter sand. The lateral arms should be checked for even spacing around the hub before closing the tank. Professional installation is recommended for those unfamiliar with sand filter servicing to ensure correct sand refill quantities and valve re-commissioning.
