Fluidra - Sand Filter Manifold Lateral Arm 1½" 425 mm

Fluidra – Sand Filter Manifold Lateral Arm 1½” 425 mm

This is a genuine Fluidra replacement manifold lateral arm for the Europe Filter series commercial sand filters. Measuring 425 mm in length with a 1½” connection, it forms part of the underdrain manifold assembly inside the filter tank, distributing water evenly through the sand bed during filtration and collecting filtered water during the backwash cycle.

Compatibility

This lateral arm is designed specifically for the Fluidra Europe Filter Ø1800 mm – 125 mm outlet, 1.0 m bed depth, rated at 2.5 kg/cm² (2.5 bar). The Europe Filter range is a polyester and fibreglass commercial sand filter line used in public pools, water parks and large aquatic facilities. Always cross-reference the parent filter model and manifold configuration before ordering to ensure an exact fit.

Why Genuine Matters

As a genuine Fluidra OEM part, this lateral arm is manufactured to the precise dimensions and tolerances required for the Europe Filter underdrain assembly. Aftermarket or incorrectly sized arms can cause uneven flow distribution, sand bypass into the pool, or reduced filtration performance — all of which are avoided by using the correct genuine replacement.

Installation

Replacing a manifold lateral arm requires draining and opening the filter tank, removing the filter media, and accessing the underdrain assembly. Given the large tank diameter and commercial-grade construction of the Europe Filter Ø1800 series, this work should be carried out by a qualified pool technician. Ensure all lateral arms in the assembly are inspected for wear at the same time to maintain balanced underdrain performance.
