This is the genuine AstralPool replacement diffuser support set designed specifically for the Vic Filter \u00d81400 1\u00bd” 1.0M 2.5 kg\/cm\u00b2 (parent SKU 11523N). It is the structural mounting assembly that holds the diffuser head in the correct position at the top of the filter tank, ensuring even distribution of incoming water across the sand bed. Sourced directly from Fluidra\/AstralPool, it corresponds to position 19 in the official exploded view diagram.<\/p>\n
This diffuser support set is engineered exclusively for the AstralPool Vic Filter with a 1400 mm tank diameter, 1\u00bd” connections, and a maximum working pressure of 2.5 kg\/cm\u00b2 (parent SKU 11523N). The Vic Filter is AstralPool’s industrial-grade bobbin-wound sand filter range, and internal components are not interchangeable across different tank diameters or pressure ratings \u2014 always verify your filter’s model number and exploded view position before ordering.<\/p>\n
The diffuser support set plays a critical role in maintaining the correct freeboard \u2014 the distance between the top of the sand bed and the diffuser head \u2014 which is key to uniform water distribution during filtration and preventing sand from being drawn into the laterals during backwash. Using a genuine AstralPool part guarantees exact dimensional fit, material compatibility (ABS\/PVC construction consistent with the Vic Filter range), and long-term reliability under commercial pool operating pressures.<\/p>\n
Replacement of the diffuser support set requires draining and opening the filter tank via the top cover. The Vic Filter features a quick-closing top cover system with a 400 \u00d7 500 mm access opening, which aids serviceability. It is recommended that installation be carried out by a qualified pool technician familiar with large-format commercial sand filters to ensure correct reassembly and a safe return to service.<\/p>","protected":false},"excerpt":{"rendered":"
