Fluidra - Diffuser Assembly for Delta 1000/1200 Sand Filter (Ø1000–1200 mm)

Fluidra – Diffuser Assembly for Delta 1000/1200 Sand Filter (Ø1000–1200 mm)

This is the genuine Fluidra replacement diffuser assembly designed for the Delta 1000 and Delta 1200 high-performance laminated sand filters in the Ø1000 mm and Ø1200 mm tank sizes. The diffuser distributes incoming water evenly across the filter bed, ensuring consistent filtration performance and preventing channelling through the sand media.

Compatibility

This assembly is specifically engineered for Fluidra’s Delta 1000 and Delta 1200 series laminated sand filters fitted with Ø1000 mm or Ø1200 mm tanks. The Delta range is available with either a collector arm system or a nozzle plate collector system — always confirm your filter’s internal configuration before ordering. It is not compatible with the smaller Ø650 mm or Ø800 mm Delta tank variants.

Why Genuine Matters

Genuine Fluidra parts are manufactured to the exact tolerances of the original filter assembly, ensuring a secure fit within the filter vessel and maintaining compliance with EN 16713-1 filtration standards. Using an original replacement avoids the pressure drop, bypassing, or uneven flow distribution that can result from ill-fitting aftermarket components — critical in commercial and public pool installations operating at high flow rates.

Installation

The diffuser assembly is an internal component accessed through the filter’s top or side manhole entry. On the Ø1000 and Ø1200 mm Delta models, access is via the DN 400 bolt-down lid. Professional installation is recommended given the size and operating pressures of these commercial-grade filters. Always depressurise and isolate the filter before beginning any internal work.
