AstralPool – Diffuser Assembly for Europe Filter Ø1400 – 90 mm Inlet

This is the genuine AstralPool replacement diffuser assembly (position 17 in the official Fluidra exploded view) for the AstralPool Europe Filter Ø1400 mm with 90 mm inlet connections, 1.2 m filter bed height, and a maximum working pressure of 2.5 kg/cm². The diffuser is the internal conical component that distributes incoming pool water evenly across the full surface of the filter media bed, maximising filtration efficiency and preventing channelling through the sand or glass media.

Compatibility

This diffuser assembly is engineered exclusively for the AstralPool Europe Filter Ø1400 – 90 mm, 1.2 m bed height, 2.5 kg/cm² (parent SKU 21512). The Europe filter range is a large-format, corrosion-resistant polyester and fibreglass commercial/semi-commercial sand filter suited to high-flow pool installations. Always cross-reference your filter’s model label and the official exploded view (position 17) before ordering to confirm fitment.

Why Genuine Matters

A diffuser assembly manufactured to AstralPool factory tolerances ensures a precise fit inside the large-diameter tank, maintaining the correct flow path through the filter media. Non-genuine substitutes may cause uneven water distribution, reduced filtration performance, or premature wear on surrounding components. As a direct OEM replacement, this part restores the filter to its original specification without modification.

Installation

Replacement of the diffuser assembly requires draining and opening the filter tank. The assembly mounts centrally at the inlet inside the vessel and must be secured correctly before the media bed is recharged. Professional installation by a qualified pool technician is recommended, particularly given the large tank diameter and operating pressures involved.
