The TRN-series is a submersible self-aspiration aerator designed for aeration and mixing of wastewater. A special semi-open impeller generates negative pressure around the impeller and draws in air from above the water surface. The drawn air is mixed with water in the aerator, and the mixture is then discharged. Since the mixture of air and water is performed under a pressurized state, it contributes to highly efficient dissolution of oxygen.

Application to Deeper Installation
Each aerator has a limit in its installation depth, but Tsurumi provides an optional device by which the aerator can be installed in deeper places. It is a simple stand or a stand with draft tube. Details are available on request.
