The Aqua One Ocellaris 139i Impeller set (part #25139i) is a genuine factory replacement component designed exclusively for the Aqua One Ocellaris 1400 and Ocellaris 1400UVC external canister filters. As the only moving part inside the filter head, it is responsible for spinning at high speeds to draw water through the filtration media and pump it back into the aquarium.
Key Features & Specifications
- Complete Assembly: The set comes as a drop-in replacement that includes the magnetic impeller, ceramic shaft, and rubber end caps/bushings (grommets).
- Material: Features a durable ceramic central shaft to ensure quiet operation and compatibility with both freshwater and marine setups.
- Performance: Engineered for low maintenance, high energy efficiency, and quiet running.
When to Replace
Because filter impellers spin 24 hours a day, 7 days a week, physical wear is inevitable. Manufacturers and aquatic specialists recommend replacing the 139i impeller every 6 to 12 months to prevent performance drops.
You should change the impeller immediately if you notice:
- A significant reduction in water flow rate or water trickling from the output.
- Noisy, rattling, or grinding operations coming from the filter head.
- Visible scoring on the magnet or a snapped/bent ceramic shaft.
