SMALLER PONDS of less than ½ acre provide tremendous beauty and function to both residential and commercial properties. These waterways are often used for everything from water gardening and fishing to retention ponds and storm water basins and are found in many new development projects. However, these bodies of water are unique due to their smaller size and shallow depth and therefore are in great need of oxygen and circulation. Without aeration these small ponds are easily thrown out of ecological balance and can suffer from excessive aquatic vegetation and foul odor.

Based on the needs of the small pond owner, Otterbine developed a fractional horsepower aerating fountain and mixer with interchangeable spray patterns to operate at depths as low as 16in. This small but powerful system can provide a solution to your water quality management needs, while enhancing the natural habitat for aquatic animals and wildlife. Enjoy the cascading effects of a water feature day into night with the Deluxe Package offered on these systems. Our energy efficient Fountain Glo™ LED light systems are available with colored lens packages.

– All units are 120V
– Lighting options are available

THE FRACTIONAL SERIES Aerating Fountain and Mixer line is incredibly efficient and versatile as it is easy to handle, lightweight and can be used as both a surface spray system or easily converted to an underwater mixer.

Built on a similar platform to that of our 1HP-5HP aerator and fountain lines, the Fractional Series incorporates the same corrosion resistant materials in the construction to offer a robust unit that will offer years of trouble-free service.

The shallow operating depth makes this unit ideal for backyard ponds, ponds that contend with fluctuating water levels such as retention or detention ponds, canals, and for those with limited budgets who need water quality management.

ENJOY DAY INTO NIGHT! Deluxe Packages include the standard package plus a 2-light LED light set and quick disconnect cable on both the unit and lights.
