Combined Surface Aerator and Mixer

The ATB HSA-HSM Combined Surface Aerator and Mixer combines a surface aerator and a vertical agitator in one unit. Both motors can be switched on and off independently of each other. The unit contains a direct drive, high efficiency surface aerator with an optimised centrifugal impeller, combined with a direct drive high efficiency mixer with an optimised axial impeller. It creates a micro bubble formation as a result of optimal transfer of kinetic energy into the water surface. The mixing pattern leaves no dead spots in the tank volume.
