Key features

• Genuine part: Sourced from Fluidra Australia as an original Astral Pool spare, not a generic copy.

• Precise retention: Snap-fit design holds the cooling fan in its groove to maintain alignment and airflow.

• Durable construction: Corrosion‑resistant metal for reliability in pool equipment environments.

• Quick install: Tool‑assisted press fit; no adhesives or complex assembly.

• Low-cost prevention: Helps reduce bearing strain, fan rub, and overheating risk by keeping the fan stable.

Compatibility

• Use case: Cooling fan retention on Astral Pool pump motors that use the Notos fan and matching circlip groove.

• Model families (typical): Commonly found on Astral/Hurlcon lines where a Notos motor cooling fan is fitted. If your existing fan has a circlip groove, this part is likely the correct style.

• Fit check: Confirm your pump’s motor fan has a circular groove sized for a standard circlip. If in doubt, request a photo match before ordering.

Tip: If your current fan is loose, wobbly, or has a missing/bent clip, replacing the circlip usually restores proper airflow and reduces noise.
