AstralPool – Diffuser Assembly BP.1400-110 Elbow

This is the genuine AstralPool replacement diffuser assembly for the BP.1400-110 large-format sand filter, featuring an elbow (angled) configuration. The diffuser is a critical internal component that distributes water evenly across the filter bed during the filtration cycle, ensuring optimal flow efficiency and filter performance. It corresponds to position 25A in the official Fluidra exploded view diagram.

Compatibility

This diffuser assembly is designed specifically for AstralPool sand filters in the BP series with a 1,400 mm tank diameter and a 110 mm pipe connection. Always cross-reference the exploded view diagram for your filter model (parent catalogue reference 703) to confirm this is the correct part before ordering. Using the official Fluidra spare parts catalogue reference 25A is the most reliable way to verify fitment.

Why Genuine Matters

An OEM AstralPool diffuser assembly is manufactured to the exact tolerances of the original part, ensuring a leak-free fit and maintaining the rated filtration performance of your system. Aftermarket alternatives may differ in geometry or material grade, risking poor water distribution, premature wear, or filter bypass — issues that a genuine Fluidra-sourced part eliminates from the outset.

Installation

Replacing the diffuser assembly requires draining and opening the filter tank. The elbow design must be oriented correctly within the tank to align with the inlet flow path. Professional installation by a qualified pool technician is recommended to ensure correct seating, proper torque on any fasteners, and a safe pressure test before returning the system to service.
