TAR


Submersible Air Mixers

Air-inlet Bore(mm) 65 - 250
Motor Output(kW) 1.5 - 30

The TAR-series is a submersible air mixer that combines aeration and mixing to promote wastewater treatment at public and industrial treatment plants. The powerful current discharged from the high-performance axial-flow impeller shears the air supplied by the blower into tiny bubbles, forming a furious flow of mixed air and water that efficiently delivers oxygen throughout the wastewater. Moreover, Tsurumi's original downward 4-directional discharge design spreads that mixed flow outward along the bottom of the tank toward the edges to ensure homogeneity.
When paired with a Tsurumi rotary air blower, the TAR air mixers not only offer effective aerobic agitation but they can also be used for both aerobic and anaerobic processing by simply switching the blower on and off.

Oxygen Transfer Rate - Air Supply Rate Curves

•Conditions: Clean water, 20 ̊C, 0 mg/l DO
•Oxygen Transfer Rate may fluctuate about 10% due to water temperature, tank shape, waterquality and other factors.
 Select a model that ensures an ample air supply rate for your application.
•The max. water depth of installation is 10 m, but please contact an authorized dealer for the performance at depths of 6m or more.
