Fluidra - Diffuser Assembly Ø950 mm for PTK Arm Filters

Fluidra – Diffuser Assembly Ø950 mm for PTK Arm Filters

This is the genuine Fluidra diffuser assembly designed for the Ø950 mm tank variant of the PTK 1000 mm arm-collector sand filter series. The diffuser sits at the top of the filter’s internal arm manifold and evenly distributes incoming water across the filter bed, ensuring efficient and uniform filtration throughout the tank.

Replacing a worn or cracked diffuser restores correct flow distribution, preventing channelling through the sand bed and maintaining optimum filtration performance in commercial and large residential pool systems.

Compatibility

This diffuser assembly is a direct OEM spare for the Fluidra ARM Filters PTK 1000 mm series with a Ø650, Ø800, and Ø950 mm tank — specifically the Ø950 mm diameter variant. Always verify your filter’s tank diameter and arm-collector configuration before ordering, as PTK filters are available in multiple sizes and collector types.

Why genuine matters

As an original Fluidra part, this assembly is manufactured to the exact tolerances of the PTK filter’s internal geometry. Genuine components ensure a secure, leak-free fit within the arm manifold and are compatible with the EPDM gaskets and ABS/PVC fittings used throughout these filters, protecting long-term system reliability.

Installation

The diffuser assembly is accessed through the filter’s top lid opening. Full draining of the filter tank is required before replacement. Due to the size and internal complexity of PTK 1000 mm commercial filters, installation by a qualified pool technician is strongly recommended to ensure correct seating and torque on all connections.
