This is a genuine Fluidra replacement manifold arm (lateral) designed for the Fluidra Europe Filter with an \u00d81800 mm tank diameter. The manifold arm is a core internal component of the filter’s underdrain system, responsible for evenly distributing water across the sand bed during filtration and collecting filtered water during normal operation and backwash cycles. Replacing a damaged or broken arm restores correct flow distribution and maintains optimal filtration performance.<\/p>\n
This manifold arm assembly is specifically sized for the Fluidra Europe Filter \u00d81800 mm with a 1 m filter bed depth and a 2.5 kg\/cm\u00b2 (2.5 bar) pressure rating, using a 1\u00bd” connection. The Europe Filter \u00d81800 is a large-capacity commercial sand filter rated for flow rates of 63\u201389 m\u00b3\/hr, commonly found in public pools, hotel pools, and water parks. Always confirm your filter’s tank diameter and manifold connection size before ordering to ensure correct fitment.<\/p>\n
Using an original Fluidra manifold arm guarantees precise dimensional fit within the filter’s underdrain hub, maintaining uniform lateral spacing and correct slot sizing. Aftermarket arms can vary in dimensions or slot geometry, leading to sand bypass, uneven flow distribution, or premature failure. A genuine part also ensures continued compliance with the filter’s rated working pressure of 2.5 bar.<\/p>\n
Manifold arm replacement requires draining the filter tank and removing the sand bed to access the underdrain assembly. The arm connects to the central manifold hub and should be inspected for any damage to the hub threads or o-ring seats at the same time. Due to the scale of the \u00d81800 filter, this work is best performed by a qualified pool technician.<\/p>","protected":false},"excerpt":{"rendered":"
