Aqua-Aerobic Systems, Inc. (a subsidiary of the METAWATER Group)

- Model DDM - Direct Drive Mixer



The AquaDDM Mixer provides maximum wastewater mixing efficiency. When mixing requirements are the controlling factor, the AquaDDM mixer can reduce power costs, while delivering 3-4 times the mixing of any aerator of the same size. The ducted impeller improves pumping efficiency. The integrated flow vanes and lower input torque eliminate the need for tank baffles.
