Old vs. New Blower Technology for Aeration

Nov. 9, 2021
Learn how blowers for aeration have changed over the years, and why now may be a good time to upgrade your system.

While some elements have remained the same for years, many elements of blowers for aeration and wastewater treatment have grown, evolved and changed. From more efficient energy usage to the inception of the turbo blower, understanding what makes them different can be critical for the success of your next blower installation project.

Stephen Horne, Kaeser USA blower product manager, discusses the differences between old and new blower technologies, particularly in changes to lobe count and turbo blowers. Learn about efficiency advancements, housing improvements and how controls have advanced for more nuanced control of blower units. Horne also covers isentropic efficiency, what it means, and why Kaeser is keeping it top of mind.
