AstralPool - Bilbao Sand Filter Internal Assembly Kit Ø500 mm - SP-04-0031

AstralPool – Bilbao sand filter internal assembly kit Ø500 mm

This is the genuine AstralPool internal assembly kit designed specifically for the Bilbao two-piece clamp-ring sand filter tank with a 500 mm diameter. It contains the internal lateral distribution components that sit inside the filter vessel, ensuring water is evenly distributed through the filter media and efficiently collected after filtration. Replacing a worn or damaged internal kit restores full filtration performance to your Bilbao D.500 sand filter system.

Compatibility

This kit is engineered exclusively for the AstralPool Bilbao sand filter vessel in the 500 mm (D.500) diameter variant. It is not compatible with other Bilbao tank sizes (D.400 or D.600) or other AstralPool filter ranges such as the Europa, Cantabric, or Malaga. Always verify your filter model and diameter before ordering to ensure a correct fit.

Why genuine matters

Using a genuine AstralPool replacement kit guarantees precise dimensional tolerances and material compatibility with the original Bilbao tank body. Polypropylene construction ensures strong resistance to pool chemicals and UV exposure, maintaining a reliable seal and consistent flow performance season after season. Off-brand alternatives may compromise filtration efficiency and void any remaining equipment warranty.

Installation

The internal kit is accessed by separating the two halves of the Bilbao clamp-ring tank body — a process made straightforward by the vessel’s split design. It is recommended that installation or replacement is carried out by a qualified pool technician to ensure correct positioning of all lateral components and a proper reassembly of the tank clamp ring for a watertight seal.
