This is the genuine Fluidra replacement diffuser assembly designed specifically for the Atlas reinforced polyester sand filter with a 750 mm tank diameter. The diffuser is a critical internal component that controls the direction of water flow through the filter during both filtration and backwash cycles, ensuring efficient and even distribution across the sand bed. Replacing a worn or damaged diffuser with this OEM part restores the filter to full factory performance.<\/p>\n
During normal filtration, water from the pool enters through the collector arms and exits through the diffuser into the pool return line. During backwash and rinse cycles, this flow direction reverses, with water entering via the diffuser and exiting through the collector arms to expel trapped debris. A correctly seated, undamaged diffuser assembly is essential for maintaining hydraulic efficiency and preventing unfiltered water from bypassing the sand bed.<\/p>\n
This diffuser assembly is matched to the Fluidra Atlas sand filter range at the 750 mm tank diameter. The Atlas filter line is available in 500, 600, 750, and 900 mm diameters; always verify your filter’s tank diameter before ordering, as diffuser assemblies are not interchangeable between sizes. Refer to your filter’s exploded-view parts diagram or the model label on your tank to confirm fitment.<\/p>\n
As a genuine Fluidra OEM spare part, this diffuser assembly is manufactured to the exact tolerances required for the Atlas filter’s internal pipework and collector system. Aftermarket alternatives may not seal correctly or withstand the filter’s operating pressure, risking sand bypass and reduced water quality. Fitting a genuine part protects your warranty and ensures long-term reliability.<\/p>","protected":false},"excerpt":{"rendered":"
