Fluidra - Diffuser Assembly Ø110 mm for Europe Filter Ø1400

Fluidra – Diffuser Assembly Ø110 mm for Europe Filter Ø1400

This is the genuine Fluidra replacement diffuser assembly for the Europe Filter Ø1400 with a 110 mm connection, rated at 2.5 kg/cm². The diffuser sits at the top of the filter’s internal pipework and is responsible for evenly distributing incoming water across the entire surface of the sand bed, ensuring consistent filtration performance and efficient backwash cycles.

During normal filtration, water enters through the diffuser and passes down through the filter media; during backwash, the flow reverses through the collector arms and exits via the diffuser. A damaged or degraded diffuser assembly disrupts this flow pattern, leading to channelling in the sand bed, poor water clarity, and reduced filter efficiency — making timely replacement essential.

Compatibility

This diffuser assembly is designed specifically for the Fluidra Europe Filter range at Ø1400 mm tank diameter, with a 110 mm pipe connection and a maximum working pressure of 2.5 kg/cm² (2.5 bar). The Europe Filter is a commercial-grade polyester and fibreglass sand filter used in large public and semi-public pools. Always verify your filter’s diameter and connection size against your existing part before ordering.

Why Genuine Matters

As an OEM Fluidra part, this diffuser assembly is manufactured to the exact tolerances of the original, ensuring a secure fit within the filter vessel and reliable sealing against the internal pipework. Aftermarket alternatives may not match the correct geometry, risking water bypass around the sand bed, sand carry-over into the pool, or premature failure under pressure.

Installation

The diffuser assembly should be inspected and replaced whenever cracking, warping, or physical damage is found during routine maintenance. Before fitting, isolate the pump, fully depressurise the filter, and remove the lid. Seat the diffuser assembly carefully onto the central pipe before refilling with filter media. Professional installation by a qualified pool technician is recommended for commercial systems of this size.
