Aqua One Complete Impeller Set for Ocellaris 850 and 850UV 137i

Function

The 137i Impeller is the only moving part in an Aqua One Ocellaris 850 and 850UV external canister filter. It spins at high speed drawing water through the filter and returning it to your aquarium. Impellers spin 24 hours per day, seven days per week so wear is inevitable.

Effect on Flow Rate

The Aqua One Ocellaris 850 and 850UV are completely dependent on the impeller to produce water flow. If the 137i is dirty or worn flow rates can be reduced to a trickle.

Lifespan

Experience tells us that most impellers give of their best during the first year of their life. The 137i impeller will turn through billions of revolutions during that times so changing it yearly or at least having a spare is common sense and means your Ocellaris 850 or 850UV need never grind to a halt.

Pack size.

One 137i impeller is included per pack. The matching ceramic shaft is also included as are the top and bottom rubber ‘grommets’ which hold the impeller in place.
