AstralPool - Manifold Assembly for Aster-L 900 Filter – 2½" Connection - SP-04-0444

AstralPool – manifold assembly for Aster-L 900 filter – 2½” connection

This genuine AstralPool manifold assembly is the complete internal collector arm unit designed for the AstralPool Aster-L laminated sand filter with a 900 mm vessel diameter and 2½” connections. The manifold sits at the base of the filter tank and is responsible for collecting filtered water and directing it back to the pool while preventing sand or glass filter media from escaping into the return line. Replacing a cracked or damaged manifold assembly restores full filtration efficiency and protects your pool’s circulation system.

Compatibility

This assembly is engineered specifically for the AstralPool Aster-L 900 mm laminated polyester and fibreglass sand filter range with 2½” port connections. The Aster-L 900 is designed for large private and semi-commercial pools and is compatible with silica sand, filter glass, and zeolite filtration media. Always verify your filter’s diameter and connection size before ordering to ensure a correct fit.

Why genuine matters

As a genuine OEM AstralPool spare part, this manifold assembly is manufactured to the exact tolerances of the original component, ensuring a secure, leak-free fit within the filter vessel. Third-party alternatives risk poor sealing, premature failure, or media bypass — all of which can lead to cloudy water and costly repairs. A genuine replacement also maintains compliance with EN 16713-1 filtration standards.

Installation

The manifold assembly is installed inside the filter tank and connects to the lateral collector arms that span the filter bed. The filter must be fully depressurised, drained, and the media removed before replacing the manifold. Due to the size of the Aster-L 900 vessel and the need to work inside the tank, professional installation by a qualified pool technician is strongly recommended.
