This is the genuine Fluidra diffuser assembly with support bracket, designed as an OEM replacement part for the Fluidra Volcano commercial sand filter with a tank diameter of \u00d81800 mm. The diffuser sits at the water inlet inside the filter tank and evenly distributes incoming pool water across the surface of the sand bed, ensuring consistent filtration performance and preventing channelling or disruption of the filter media.<\/p>\n
This assembly is specifically engineered for the Fluidra Volcano sand filter range in the \u00d81800 mm tank diameter variant. The Volcano series covers tank sizes from \u00d81050 mm up to \u00d82000 mm, so it is important to verify your exact tank diameter before ordering. Always cross-reference your filter model number and the part SKU to confirm fitment.<\/p>\n
A correctly functioning diffuser is critical to filtration efficiency. An incorrectly fitting or damaged diffuser can cause water to concentrate in certain areas of the sand bed, creating preferential flow paths that allow particles and contaminants to bypass the filter media entirely. Using a genuine Fluidra part guarantees the correct geometry, flow characteristics, and material quality for reliable, long-term operation.<\/p>\n
The assembly includes both the diffuser head and its support bracket, providing everything needed for a complete like-for-like replacement. Access to the diffuser requires opening the filter tank, which should only be attempted after isolating the pump and depressurising the system. Professional installation by a qualified pool technician is recommended, particularly on large commercial-grade filters of this size.<\/p>","protected":false},"excerpt":{"rendered":"
