Aeration Blower
for Wastewater-Treatment Plant

High Efficiency
at Any Operating Point

Kawasaki MAG Turbo enables stable and efficient air supply to follow up variable water inflow load such as flow capacity, air pressure and water quality, by Dual Flow Control:
Inlet Guide Vane Control and Variable Rotational Speed Control.

Dual Flow Control attains high partial load efficiency and wide range of flow capacity by shifting performance curve at the most efficient point in response to variable water inflow load. Furthermore, custom designed state-of-the-art impeller attached to the end of the shaft levitated by active magnetic bearing reduces power consumption.

Typical Configuration

The layout and supply scope can be flexible to meet customer’s needs and wants.

  • Flow Capacity Range:11,510 to 33,600 SCFM 68 °F ,14.7 psia, 36 %RH (330 to 950 m3/min 20℃ 101.3kPa 36%RH)
  • Main Power Supply 4,160V (60 Hz)

More Detail

Key Strengths for High Efficiency

Custom-Designed Impeller

Optimally designed for each project’s
specific operating conditions

The impeller is designed specifically for each project to ensure that the incidence angle at the inlet and the discharge angle are as intended. Additionally, we verify that the stress remains within allowable limits and that resonance with the natural frequency is avoided within the expected operating range.

Dual Flow Control

High efficiency at partial load
and wide range of operation

Dual flow control with variable inlet guide vanes and variable rotational speed ensures highly efficient operation at any point by adjusting the performance curve to the most efficient point in response to the required airflow and discharge pressure.

Active Magnetic Bearings

No friction loss thanks to levitation
by Active Magnetic Bearings

The rotor of the high-speed motor is levitated by active magnetic bearings with an impeller attached to the end of the shaft. Active magnetic bearings achieve no mechanical loss, quiet operation, and reduced vibration because they allow the rotor to rotate without mechanical contact.
