Fluval 07 Series Replacement Impeller Cover for 107 Canister Filter (A20123) The Fluval Replacement Impeller Cover (A20123) is a genuine OEM spare part designed specifically for the Fluval 107 Performance Canister Filter (A442). The impeller cover is a co-moulded, high-flex polymer component that sits over the impeller assembly inside the motor head — it protects the impeller, reduces vibration, and is a key contributor to the 07 Series filter's exceptionally quiet operation. Over time the impeller cover can crack, warp, or break — particularly during routine maintenance when the motor head is opened for impeller cleaning. A damaged or missing impeller cover results in increased noise, vibration, and reduced pump performance. Replacing with a genuine Fluval OEM impeller cover restores correct impeller operation and the 07 Series' signature ultra-quiet performance. Important installation note: Always ensure the impeller cover is fitted right way up when replacing — incorrect orientation will affect pump performance and noise levels.
