Durability, Efficiency, Affordability, and Serviceability: The Real-World Benefits of Geared Centrifugal Blowers

When Reliability, Efficiency, and Value All Matter
When it comes to wastewater treatment aeration, reliability and total cost of ownership matter just as much as efficiency. Plants need blower systems that perform every hour of every day—without frequent maintenance, expensive service contracts, or costly downtime. That’s why more utilities and engineers are upgrading to geared centrifugal blowers.

Innovation Recognized at WEFTEC 2025
At Inovair, we’ve taken that technology even further—engineering wastewater aeration blowers that are not only more efficient, but built to handle real-world operating environments. And this year, we were honored to be featured in the Technology Spotlight at WEFTEC 2025 to present this information to dozens of wastewater industry professionals. Here’s why Durability, Efficiency, Affordability, and Serviceability make Inovair the fastest-growing blower platform in municipal and industrial wastewater applications:

Engineered for Durability in Harsh Conditions

Wastewater treatment typically exists in hot, cold, humid, and/or dusty environments, where demand may be constantly changing. That’s why Inovair blower packages are engineered to survive in those same, extreme conditions. A key advantage of Inovair’s design is our patented oil film bearing technology, which eliminates metal-to-metal contact and provides unlimited life. Real-world installations prove their durability:
  • Jerome, ID – Handles wide pressure swings daily
  • King City, CA – Operates outdoors in heavy dust from surrounding agriculture
  • Warrensburg, MO – Over 11,000 start/stop cycles with zero maintenance
Inovair blowers are designed and manufactured in the USA and are fully BABA compliant, making them ideal for publicly funded projects. Learn more about our commitment to American manufacturing.

Efficiency Without Complexity

Energy costs can account for up to 60% of plant operating expenses, and aeration is typically the largest energy consumer. Inovair geared centrifugal blowers offer significant energy savings over multistage and PD blowers, and deliver comparable and often better performance than turbo blowers—without the complexity of proprietary high-speed motors, VFDs, and control systems.

With 70+ aerodynamic impeller designs and up to 60–75% turndown, Inovair achieves high efficiency across varying flow and pressure demands. Standard VFD control adjusts blower output automatically, helping utilities optimize system efficiency.

Affordability: Lower Installation and Lifecycle Cost

Unlike some other blower manufacturers, Inovair does not use proprietary components. We use standard motors, VFDs, and industrial components so parts are easy to source nationwide and long-term support cost stays low. Our system design also simplifies retrofit projects and reduces installation cost.

Case Study – Paducah, KY

  • Reused existing VFDs to minimize capital cost

  • Achieved efficiency gains without major electrical upgrades

  • Spotting red flags in proposals before they become problems

  • Reduced project lead time

Simple to Service. Designed for Uptime.

Some blower manufacturers require service contracts and factory-only maintenance. Inovair takes a different approach—we empower plant teams to self-maintain. With straightforward access panels, no proprietary software, and readily-available and locally-sourced parts, our blowers are built for long-term serviceability and reliability.

Additional service advantages:
✔ Operator-friendly maintenance
✔ Remote or local VFD mounting options
✔ Minimal downtime design
✔ Built-in diagnostics and performance monitoring


One Blower Platform. Every Wastewater Process.

Inovair geared centrifugal blowers serve every major wastewater process:
• Aeration basins (conventional activated sludge)
• Sequencing Batch Reactors (SBRs)
• Digesters
• Equalization tanks
• Lagoons

Coatesville, PA is another great case study example: Inovair blowers serve both digesters and aeration, controlled through an Inovair UL508A master control panel with DO, ORP, and pH monitoring for full system automation.

Flexible Configurations for Any Facility

Inovair offers a complete range of blower sizes:
Model Horsepower Range
IM-20 25–150 HP
IM-30 25–200 HP (stackable)
IM-40 125–300 HP
IM-50 300–600 HP

Our blower packages support indoor or outdoor installations and connect easily to existing piping layouts using horizontal or vertical discharge. They can even run in parallel with other blower types—including PD, multistage, turbo, or air-bearing blowers—just like they do at Lafayette, CO.
