Fluval Replacement Impeller Cover for 103 / 203 External Canister Filter (A650 / A660)

The Fluval Replacement Impeller Cover is a genuine OEM replacement part designed specifically for the Fluval 103 (A650) and Fluval 203 (A660) external canister filters. The impeller cover sits over the impeller assembly inside the filter motor head — securing the impeller in place, protecting it from debris, reducing vibration, and ensuring smooth, efficient water flow through the filter.

If the impeller cover becomes cracked, broken, or missing, the impeller can move excessively — causing increased noise, vibration, reduced flow, and potential impeller damage. Replacing with a genuine Fluval OEM impeller cover restores correct impeller operation and full filter performance.
