IM-20 20-150 HP

Industry-Exclusive Design

The Inovair IM-20 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-20 solves this problem through modularity without burdening the overall blower footprint.
