Fluidra - Manifold Arm Assembly for Volcano Sand Filter Ø1400 mm

Fluidra – Manifold Arm Assembly for Volcano Sand Filter Ø1400 mm

This is the genuine Fluidra manifold arm assembly designed specifically for the Volcano commercial sand filter with a tank diameter of 1400 mm. The assembly forms the internal lateral collector system at the base of the filter tank, gathering filtered water after it has passed through the sand bed and evenly distributing the backwash flow during cleaning cycles. It is a critical internal component for maintaining efficient filtration and effective backwashing in high-flow commercial pool installations.

Compatibility

This manifold arm assembly is engineered exclusively for the Fluidra Volcano Filter range covering tank diameters from Ø1050 mm to Ø2000 mm, and is correctly sized for the Ø1400 mm tank. Always verify your filter’s tank diameter before ordering — a separate assembly reference is available for the Ø950–1050 mm size range. Consult your Fluidra parts diagram or an authorised technician if you are unsure of your exact model.

Why Genuine Matters

The manifold arm assembly must seat precisely within the tank base and align correctly with the underdrain to maintain an effective seal between filtered and unfiltered water. Genuine Fluidra parts are manufactured to exact dimensional tolerances, ensuring a secure fit, reliable performance under commercial flow rates, and full compatibility with the Volcano filter’s pressure rating. Third-party alternatives risk poor fitment, bypass of the filter bed, and premature failure.

Installation

Replacement of the manifold arm assembly requires draining and opening the filter tank and removing the existing collector from the underdrain hub. The new assembly should be carefully seated and checked for secure engagement before the filter is refilled and returned to service. Installation by a qualified pool technician is strongly recommended for commercial-scale equipment of this size.
