This is the genuine Fluidra replacement diffuser assembly designed for the \u00d8900 mm sand filter with a 2\u00bd” male-thread connection and a rated flow of 31,000 l\/h (without selector valve). The diffuser sits at the top of the filter tank and distributes incoming water evenly across the entire sand bed, ensuring consistent filtration performance and preventing channelling through the filter media.<\/p>\n
This diffuser assembly is a direct OEM replacement for Fluidra \u00d8900 mm sand filters rated at 31,000 l\/h with a 2\u00bd” outlet and no integrated selector valve. Always cross-reference the parent filter model and the SKU before ordering, as diffuser assemblies are size- and connection-specific \u2014 an incorrect size will not seal or distribute flow correctly.<\/p>\n
Genuine Fluidra parts are manufactured to the exact tolerances of the original equipment, ensuring a precise fit, long service life, and maintained filter efficiency. Third-party alternatives may differ in thread pitch, diameter, or material grade, risking leaks or reduced filtration quality in a high-flow commercial or semi-commercial installation.<\/p>\n
The diffuser assembly is accessed by opening the filter tank lid. The unit should be carefully aligned and hand-tightened before any tools are used on the 2\u00bd” male-thread connection to avoid cross-threading. Professional installation is recommended for filters of this size and flow rate; always depressurise and isolate the system before beginning work.<\/p>","protected":false},"excerpt":{"rendered":"
