AstralPool – Filter Diffuser Assembly D.500

This is a genuine AstralPool replacement diffuser assembly designed for AstralPool pool sand or media filters with a 500 mm (Ø500) diameter tank. The diffuser assembly sits inside the filter vessel and is responsible for evenly distributing water through the filter media, ensuring consistent filtration performance. It corresponds to position 15 in the official Fluidra exploded-view diagram for the Pool Spare Parts Catalogue (parent SKU 55610100).

Compatibility

This diffuser assembly is specifically designed for AstralPool Ø500 mm filter tanks listed under the Pool Spare Parts Catalogue (parent SKU 55610100). Always cross-reference your filter’s model number and the official Fluidra exploded-view diagram (position 15) before ordering to confirm fitment. If in doubt, consult your filter’s documentation or contact a qualified pool technician.

Why Genuine Matters

Using a genuine AstralPool OEM part ensures the diffuser assembly matches the exact dimensions and material tolerances of your filter, maintaining rated flow rates and filtration efficiency. Aftermarket alternatives may not seal correctly against the filter body, risking channelling, media bypass, or premature failure. Genuine parts also protect any remaining warranty on your filter system.

Installation

The diffuser assembly is an internal filter component. Installation requires draining and opening the filter vessel, then carefully removing the old diffuser before fitting the replacement. Professional installation is recommended to ensure correct seating and to avoid damage to the filter body or multiport valve connections.
