Fluidra – Diffuser Support Tube Ø125 mm for Europe Filter 1800

This is the genuine Fluidra diffuser support tube with a 125 mm diameter, designed for use in the Fluidra Europe Filter Ø1800 commercial sand filter (1.0 m filter bed, 2.5 kg/cm²). It forms the central backbone of the internal collector assembly, holding the lateral diffuser arms in the correct position so that water is evenly distributed through the sand bed during both filtration and backwash cycles.

Compatibility

This support tube is a direct OEM spare part for the Fluidra Europe Filter Ø1800 – 125 mm connection – 1.0 m filter bed – 2.5 kg/cm² (Fluidra assembly reference 21505). The Europe Filter range is a series of polyester and fibreglass commercial-grade sand filters that are totally corrosion-resistant and salt-water resistant. Always verify your filter’s diameter, bed height, and connection size before ordering to ensure a correct fit.

Why Genuine Matters

Using a genuine Fluidra replacement tube guarantees an exact dimensional match with the collector assembly, preventing bypass of unfiltered water and maintaining the filter’s rated hydraulic performance. Non-OEM alternatives may differ in diameter or material, compromising seal integrity and potentially voiding the filter warranty.

Installation

Replacement of the diffuser support tube requires draining the filter tank and removing the top lid and collector assembly. Due to the size and working pressure of the Europe Filter 1800, this work should be carried out by a qualified pool technician. Ensure all O-rings and seals on the collector assembly are inspected and replaced as needed during the service.
