Fluidra - Diffuser Support Tube Ø140 mm for Praga Filter Ø1800

Fluidra – Diffuser Support Tube Ø140 mm for Praga Filter Ø1800

This is the genuine Fluidra diffuser support tube (Ø140 mm) designed for the AstralPool Praga commercial sand filter with an Ø1800 mm tank diameter. It forms part of the internal diffuser and manifold assembly, holding the diffuser plate correctly centred so that incoming water is distributed evenly across the full filter bed for consistent, efficient filtration.

Compatibility

This part is specifically sized for the Ø1800 mm variant of the Fluidra AstralPool Praga bobbin-wound fibreglass sand filter range. The Praga series spans tank diameters from Ø1050 mm up to Ø2000 mm, so always verify your tank diameter and manifold configuration (Ø140 arm size) before ordering, as support tubes are not interchangeable across different diameter configurations.

Why Genuine Matters

Fluidra OEM components are manufactured to exact tolerances, ensuring a precise fit within the filter vessel and compatibility with the existing collector arm assembly. A correctly seated diffuser support tube prevents water from bypassing the sand bed, maintaining filtration efficiency and protecting your pump from unfiltered debris. Third-party alternatives may differ in length or diameter, leading to poor water distribution or premature failure.

Installation

Installation requires draining the filter tank and accessing the internal manifold assembly. The support tube locates between the diffuser plate and the central collector, and should be inspected for cracks or deformation whenever the filter is opened for media replacement. For large commercial Praga installations, professional servicing is recommended to ensure correct reassembly of the full diffuser and collector system.
