Highest Efficiency Aerodynamics

With decades of experience and proven capabilities, Inovair is able to deliver best-in-class efficiency and durability for your demanding applications. This high efficiency, thanks to state-of-the art compressor and gearbox designs, helps optimize both performance and energy consumption. From the impeller blade shapes and volute clearances to the materials and manufacturing processes employed, Inovair provides reliable performance matched perfectly and uniquely to each application.

More Robust Designs & Manufcturing

The 1200GS utilizes a rugged single-stage gearbox design with high precision helical gears and angular contact bearings, and a state-of-the-art aerospace carbon seal for oil-free air. Impellers are designed in-house and manufactured from 7075 T-6 aircraft aluminum on Inovair’s 5-axis CNC mills, which increases strength and avoids casting cracks or flaws. No competing product even remotely compares to the capabilities and durability of the 1200GS.

12 Options, Optimized Efficiency for Your Application

With three product models and more than twelve (12) different compressor options, each application is optimized for maximum efficiency. Compressor wheels are designed to have unique combinations of diameters (inducers and reducers), blade shapes, and number of blades. To control the air flow even more, compressor housings are engineered with different volute designs. Whatever your requirements, Inovair has the best blower solution that is optimized for any operating point of airflow. In high volume cases, custom aerodynamic designs have also been implemented.

Most Durable Drive System

Our unique drive system is what makes the Inovair product so durable. No other product utilizes gearing like that on the Inovair 1200GS. Belts struggle with small diameter pulleys, as they cause more belt slippage and put a much high stress or load on the belt. The result is frequent belt changes and/or belt failure. By utilizing a gear step-up in the compressor head unit, the Inovair 1200GS has a significantly larger diameter blower pulley and, thus, a drastic improvement in belt life.

Designed, Manufactured & Serviced in the USA

When it comes to a supplier’s ability to deliver quality and availability, location matters. Inovair is not only headquartered in the heartland of America, but most operations, from engineering to manufacturing to service, are within the same facility. Our vertical integration means shorter leadtimes for parts and manufacturing. This creates a collaborative environment with lean design, manufacturing, and servicing practices. This product is also available for purchase direct from the Inovair factory.

Hassle-Free Maintenance

No more broken belts or frequent belt changes. Inovair products are designed to be maintained in the field by the equipment operator in just a few minutes. All our maintenance tasks have instructional videos on our website. Total cost of ownership includes the cost of servicing the unit for the useful life. Inovairs products are engineered to require the least effort and lowest cost to maintain.
