For the purpose of design, the turbo blowers had to be pre-selected at an early stage of the detailed engineering design. In 2009, the Ontario Clean Water Agency (OCWA) had undertaken a comprehensive assessment of turbo blowers. From among the six invited vendors, from three continents, APG-Neuros Inc. was found to be the front-runner and preselected for this project. The most important characteristic of the Neuros blowers is their high efficiency.
Additional characteristics include: permanent magnet synchronous motor; bump foil air bearing; forged single stage impeller; Allen Bradley control panel; CSA certification; relatively small footprint; low noise level; no lubricants (oil/grease); virtually zero maintenance; and, essentially no vibration.
