AstralPool - Filter Manifold Assembly for Lisboa Filters Top Ø650 mm (1") - SP-04-0195

AstralPool – Filter Manifold Assembly for Lisboa Filters Top Ø650 mm (1″)

This is the genuine AstralPool replacement manifold assembly designed specifically for the Lisboa Filters Top FST-650 sand filter (650 mm diameter). The manifold — consisting of a central hub and lateral arms — sits inside the filter tank and is responsible for collecting water that has passed through the filter media and returning it cleanly to the pool, while preventing sand or glass particles from escaping into the return line. Replacing a cracked or damaged manifold assembly restores full filtration efficiency and prevents filter media from bypassing into the pool.

Compatibilité

This manifold assembly is engineered exclusively for the AstralPool Lisboa Filters Top range with a 650 mm tank diameter (model FST-650). It occupies position 11 in the official Fluidra exploded view diagram for this filter series. Always verify your filter model and diameter before ordering, as manifold assemblies are not interchangeable between different tank sizes within the Lisboa range.

Pourquoi l'authenticité est importante

A genuine AstralPool manifold assembly is manufactured to exact dimensional tolerances, ensuring a secure, leak-free fit within the FST-650 tank. The 1″ lateral connections are sized to match the filter’s internal flow design, maximising filtration surface contact and hydraulic efficiency. Third-party alternatives may differ in arm length, port sizing, or plastic formulation, risking poor sealing and media bypass.

Installation

Installation requires draining the filter tank and removing the multiport valve to access the internals. The manifold assembly slots into the central standpipe fitting at the base of the tank, with lateral arms arranged radially across the filter bed. Correct seating of all laterals is essential to prevent gaps through which filter media could escape. Professional installation is recommended if you are unfamiliar with filter internals.
