AERATING DEVICE

摘要

An aerating device for introducing air into a liquid includes a housing having a first rotor mounted on a shaft for rotation relative to the housing. The rotor includes a series of disks disposed in spaced relation along the shaft. The shaft encloses a drive motor for selectively rotating the shaft and at least one of the disks includes surface protrusions for imparting energy to the liquid as the rotor is rotated.
