Fluidra - Collector Assembly for Aster Sand Filter Ø750 mm

Fluidra – Collector Assembly for Aster Sand Filter Ø750 mm

This genuine Fluidra collector assembly is the complete underdrain hub-and-lateral unit designed for the AstralPool Aster laminated sand filter with a 750 mm tank diameter and a maximum flow rate of 22,000 l/h. Positioned at the base of the filter tank, it collects filtered water through its slotted laterals and channels it back to the pool, while also ensuring thorough fluidisation of the filter bed during backwash cycles.

Compatibility

This collector assembly is specifically sized for the Fluidra AstralPool Aster laminated fibreglass sand filter with a Ø750 mm tank and 2″ side connections rated at 22,000 l/h. Always verify your filter’s tank diameter and flow rating before ordering, as collector assemblies are not interchangeable between different tank sizes in the Aster range.

Why Genuine Matters

A genuine Fluidra replacement ensures the correct fit, lateral slot dimensions, and material grade — critical for maintaining optimal filtration velocity and preventing sand bypass. The Aster filter is designed to operate at up to 50 m³/h/m² and a maximum working pressure of 2.5 bar; an ill-fitting aftermarket collector can compromise both filtration performance and pressure integrity.

Installation

The collector assembly fits into the lower section of the filter tank and connects to the central standpipe. During replacement, drain the filter completely, remove all sand media, and carefully extract the old assembly before seating the new unit. Professional installation is recommended to ensure the laterals are evenly distributed and the assembly is correctly seated before recharging with filter media.
