IO-20 25-100 HP


The Inovair IO Series is the most compact and economical geared centrifugal blower on the market. The vertical design places the blower directly above the motor and results in an extremely compact footprint of 35” x 41”. This design, combined with Inovair’s 2200 integrally geared compressor, TEFC induction motors and other standard components, produces a reliable, cost-effective blower for wastewater applications. Combining these design features with the IO Series’ proven 10-35% energy savings, results in a unit that provides a high ROI and rapid payback. This rugged blower package also provides the long life and high pressure capability that are typical of integrally geared centrifugal designs. The Inovair IO Series blowers deliver the lowest cost per cfm and meets a wide range of airflow demands. Inovair geared centrifugal blowers are the ideal solution for bringing efficiency to lower HP applications. With proven durability, best in class efficiency, and advanced airflow controls, the Inovair IO Series blower package can improve operational performance while also significantly reducing operating costs.
