AstralPool – sand filter diffuser assembly Ø 600 mm (serial no. < 03G919718)

This is a genuine AstralPool replacement diffuser assembly for 600 mm diameter sand filters with a serial number below 03G919718. The diffuser sits at the top of the filter tank and evenly distributes incoming pool water across the sand bed, ensuring consistent filtration performance and preventing channelling through the filter media.

Compatibility

This diffuser assembly is designed specifically for AstralPool 600 mm (Ø 600 mm) sand filters manufactured with a serial number below 03G919718. Always verify your filter’s serial number before ordering, as a later diffuser design was introduced from serial number 03G919718 onwards. If you are unsure of your serial number, it can be found on the filter’s identification label.

Why genuine matters

Manufactured from highly resistant PVC and polypropylene (PP) plastics, this OEM part is engineered to the precise dimensions of the original component. Using a genuine AstralPool diffuser ensures a correct fit, maintains the filter’s rated maximum filtration speed of 50 m³/h/m² and maximum working pressure of 2.5 bar, and protects the long-term performance of your filtration system.

Installation

The diffuser assembly is accessed by opening the filter’s screw-free lid. It is recommended that installation is carried out by a qualified pool technician to ensure correct seating and to avoid damage to the filter body or internal components. Always depressurise and isolate the filter from the pump before beginning any service work.
