Otterbine Gemini Aerating Fountain


Otterbine Gemini Aerating Fountain

Offering tremendous beauty and incredible aeration strength, the dynamic plume of the Gemini pattern works well in any setting.

Designed to give the best of both worlds by offering function and beauty, the Gemini surface spray aerator can operate in as little as 75cm of water and can move over three times as much water than decorative patterns, thanks to its open-throat propeller design.

Providing an attractive display with the capability to manage severe aquatic environments, it’s easy to see why the Gemini is particularly popular with golf courses, commercial complexes and landscape contractors.
