The custom engineered system uses the Tideflex TFA coarse bubble diffuser to provide rapid mixing while Tideflex Technologies' Tubeflex Fine Bubble Air Diffuser provides the fine bubble supplement. This combination increases transfer efficiency due to the entrainment in higher velocity loops created by the TFA. The Fine Bubble and Coarse Bubble Air Diffusers incorporate patented Tideflex Check Valve technology to prevent backflow and clogging of the diffusers. The combined system reduces energy use and lowers total airflow requirements.
