AstralPool – Diffuser Assembly 140mm for Europe Filter Ø1800

This is the genuine AstralPool replacement diffuser assembly (Ø140 mm) designed specifically for the AstralPool Europe Filter Ø1800-140mm, 1.0 m filter bed, 2.5 kg/cm² (model 21506). The diffuser sits inside the filter tank and evenly distributes water across the sand bed, ensuring consistent filtration performance. Replacing a worn or cracked diffuser restores correct flow patterns and helps maintain the filter’s rated efficiency.

Compatibility

This diffuser assembly is made exclusively for the AstralPool Europe Filter Ø1800-140mm, 1.0 m filter bed, 2.5 kg/cm² (parent model 21506). It corresponds to position 27 in the official Fluidra exploded-view diagram for that filter. Do not attempt to fit this part to other Europe Filter diameters or outlet sizes, as the geometry and flow characteristics differ between models.

Why Genuine Matters

The Europe Filter range is a heavy-duty, commercial-grade laminated polyester and fibreglass sand filter built for corrosion resistance and long service life. Using a genuine AstralPool diffuser assembly guarantees the precise dimensions and material specification needed to maintain the filter’s rated working pressure of 2.5 kg/cm² and its full range of filtration velocities. Off-brand substitutes risk poor water distribution, channelling through the sand bed, and premature wear on surrounding components.

Installation

Access to the diffuser requires opening the filter’s top lid and removing the internal collector/diffuser stack. We recommend consulting the official Fluidra exploded-view diagram (position 27) and having a qualified pool technician carry out the work to ensure correct reassembly, safe pressure testing, and uninterrupted pool operation.
