Fluidra - Diffuser Support Tube Ø125 mm for Ø2000 Sand Filter

Fluidra – Diffuser Support Tube Ø125 mm for Ø2000 Sand Filter

This is the genuine Fluidra diffuser support tube with a 125 mm diameter, designed for use in large-format Fluidra sand filters with a Ø2000 mm tank. The support tube is the central structural component that positions and holds the lateral diffuser arms correctly inside the filter vessel, ensuring even distribution of water through the filter media. Without a sound support tube, the diffuser system cannot function correctly, leading to channelling and poor filtration.

Compatibility

This part is designed for Fluidra sand filters with a Ø2000 mm tank that use a 125 mm diameter diffuser support tube. It is intended for large commercial or semi-commercial installations. Always cross-reference your filter’s model number and existing part dimensions before ordering, as Fluidra produces diffuser support tubes in multiple diameters (e.g. 90 mm, 110 mm, 125 mm) across the Ø1050–2000 mm filter range.

Why Genuine Matters

Using a genuine Fluidra replacement ensures the support tube meets the original dimensional tolerances, material specifications, and pressure ratings of your filter. An incorrectly sized or inferior support tube can cause the diffuser assembly to shift or collapse under operating pressure, resulting in sand bypass, damage to downstream equipment, and costly downtime. Genuine parts also maintain any existing warranty on the filter unit.

Installation

Installation requires opening the filter vessel and removing the existing diffuser assembly. The support tube should be inspected for cracks or deformation before fitting the lateral arms. Due to the size and weight of Ø2000 mm filter internals, this work is best carried out by a qualified pool technician. Ensure the filter is fully depressurised and isolated before beginning any internal maintenance.
