Otterbine Barebo Inc. expanded its Air Flo 2 diffused air system product line by releasing 2-dome and 1-dome diffuser manifold options to the original 4-dome option. With the release of the 2-dome and 1-dome diffuser manifolds, module Air Flo 2 systems are available through Otterbine allowing customers the unique opportunity to create custom Air Flo 2 systems.

Although highly effective in ponds and lakes with depths of 6ft–40ft (2m-12m), there is a direct correlation between performance efficiency and depth of operation in diffused air systems. In essence, the greater the depth the more efficient a system will be.

To illustrate, diffused air systems pump air to diffusers at the pond bottom that is released as a column of air that widens as it travels up through the water column. When air is released at deeper depths more oxygen is transferred throughout the water due to a larger area coming in contact with air for a longer duration. In shallower applications there is less opportunity for oxygen transfer due to less area and contact time occurring as air travels up from the pond bottom. In order to achieve the same aeration at shallower depths it is necessary to spread additional manifolds across the pond bottom.

Due to varying depths in most ponds and lakes, Otterbine’s Air Flo 2 Module Systems permit the user to achieve maximum performance efficiencies by determining and placing properly sized manifolds at appropriate locations based off the depth and need of aeration throughout the water feature.
