The Hagen Fluval 404/405 Impeller replaces the impeller for the Fluval 404/405 canister filter. Replacing an old impeller is essential to keep your filter running powerfully and efficiently.
Old impellers can result in decreased water flow, poor circulation, and, in some cases, even an unpleasant grinding noise. Replace the impeller to reinvigorate your filter with strong, silent water pull and maximum circulation.
Impeller shaft is sold separately.
Note: Will not fit Fluval 104/204 or 304/305 canister filters.
