The most recent advancement to surface aerator technology can be seen in the LANDY-7 impeller. The Landy impellers have always incorporated a sturdy design with zero failures due to cracked, sheared, or broken impeller blades.
This new impeller increases oxygen transfer efficiency and reduces axial and radial loads. The LANDY-7 provides a guaranteed minimum efficiency of 3.8 pounds of oxygen per horsepower hour. This improved transfer efficiency saves significant operational costs over the life of the equipment. The reduced axial and radial loads increase the life of the drive unit and reduce the size of support structures and beams for the surface aerators.
