This is the genuine Fluidra replacement collector manifold assembly for the PTK 1000 sand filter with a \u00d8650 mm tank. Comprising a central hub and eight slotted lateral arms, the manifold sits at the base of the filter vessel and collects filtered water evenly across the entire sand bed before returning it to the pool. It is also compatible with the equivalent Fluidra Delta series filters that succeeded the PTK 1000 range.<\/p>\n
This collector arm assembly is designed specifically for Fluidra (AstralPool) PTK 1000 commercial sand filters with a 650 mm tank diameter. The PTK 1000 series \u2014 available in \u00d8500, \u00d8650, \u00d8800, and \u00d8950 mm variants \u2014 is a fibreglass and polyester-laminated pressure filter widely used in commercial and large residential pool installations across Europe. Always verify your tank diameter and existing collector configuration before ordering.<\/p>\n
Fluidra OEM collector arms are precision-moulded to the exact slot dimensions and hub geometry of the PTK 1000 filter body, ensuring uniform flow distribution across the sand bed and preventing bypass of unfiltered water. Aftermarket alternatives may not replicate the critical slot tolerances, risking uneven filtration and sand carry-over into the pool. A genuine part also preserves any applicable Fluidra warranty on the filter vessel.<\/p>\n
The manifold assembly connects centrally to the filter’s standpipe and the eight lateral arms extend radially to sit just above the gravel support layer. Installation requires draining and opening the filter vessel \u2014 a task best performed by a qualified pool technician. Ensure the sand bed and gravel support layer are properly re-established after fitting to guarantee correct filtration performance.<\/p>","protected":false},"excerpt":{"rendered":"
