IM Series

IM Series Blowers For Wastewater Aeration

40-250 HP

Industry-Exclusive Design

The Inovair IM Series is the industry’s first truly modular blower design. Each module operates independently from any other module. Modules can be deployed as single units or in a stacked configuration.

Many wastewater treatment plants suffer from an inability to optimally regulate flow, causing them to over-aerate or blow-off excess air. Both of these negatively impact attempts to save energy. The IM Series solves this problem through modularity without burdening the overall blower footprint.
