AstralPool – Diffuser Assembly for Delta Filter 1000-1200 (Ø 650–800 mm)

This genuine AstralPool diffuser assembly is the OEM replacement component (position 21 in the official Fluidra exploded view) for the Delta Filter 1000-1200 range fitted to 650 mm and 800 mm diameter vessels. The diffuser plays a critical role in evenly distributing water flow across the filter bed, ensuring optimal filtration performance and preventing channelling through the sand media. It is engineered specifically for the Delta Filter 1000-1200 series and is sourced directly from Fluidra/AstralPool.

Compatibility

This diffuser assembly is designed exclusively for the AstralPool Delta Filter 1000-1200 in 650 mm and 800 mm diameter configurations (parent SKU 36680-0100 / 001000). The Delta Filter is a high-performance laminated polyester and fibreglass sand filter available with both collector arm and plate collector systems, rated to a maximum working pressure of 2.5 bar and compliant with EN 16713-1. Always cross-reference the exploded view diagram (position 21) before ordering to confirm fitment with your specific filter model.

Why Genuine Matters

Genuine AstralPool spare parts are manufactured to the exact tolerances of the original filter design, ensuring a correct seal, proper flow distribution, and long-term durability in commercial and residential pool environments. Using non-OEM alternatives risks poor fitment, reduced filtration efficiency, and potential damage to the filter vessel. This assembly comes directly from the Fluidra supply chain, giving you full confidence in quality and traceability.

Installation

The diffuser assembly is an internal filter component and requires draining the filter, removing the filter lid, and accessing the internal distribution system for replacement. Installation is straightforward for qualified pool technicians familiar with the Delta Filter series. We recommend consulting the official Fluidra exploded view diagram and technical datasheet for your specific filter model before proceeding.
