RAETTS Maglev Turbo Blowers A Smarter Upgrade for the Future of Wastewater Treatment
In modern wastewater treatment, efficiency and reliability define success. Many plants still rely on Roots blowers — a technology that, while robust, consumes high energy, generates excessive noise, and requires constant maintenance. Recognizing these challenges, more operators are now turning to RAETTS Maglev Turbo Blowers — an upgrade that redefines how aeration systems perform.
Recently, a wastewater treatment plant replaced its aging Roots blowers with two RAETTS Maglev blowers (95 kW each). The result? A significant leap forward in energy efficiency, noise reduction, and long-term reliability.
1. Dramatic Reduction in Electricity Consumption (OPEX)
Roots blowers typically consume very high power, forming the largest share of operational costs in wastewater aeration. In contrast, RAETTS Maglev Turbo Blowers reduce electricity consumption by 30–40%, thanks to advanced PMSM motors, three-dimensional flow impellers, and contact-free magnetic bearings.
This means for every $100,000 of annual power spent on Roots blowers, operators could save up to $40,000 per year after switching to RAETTS. The payback period is often less than two years, making this upgrade one of the fastest-returning investments in plant optimization.
2. Minimal Maintenance, Maximum Uptime
Roots blowers demand regular oil changes, belt replacements, and gear lubrication — typically costing around 5% of the equipment price every year.
RAETTS Maglev Blowers, however, operate completely oil-free. With no physical contact between the rotor and bearing, there’s virtually no wear, eliminating the need for regular overhaul or lubrication. Maintenance costs drop to nearly zero — limited only to simple air filter replacements.
As a result, operators enjoy longer uptime, reduced manpower requirements, and worry-free operation throughout the blower’s 20+ year service life.
3. Noise & Vibration: A Quiet Revolution
Roots blowers are notoriously loud — typically 110–120 dB, requiring soundproof rooms and vibration isolation.
By contrast, RAETTS Maglev Blowers operate at just 80–85 dB, with ultra-low vibration due to the magnetic suspension system. This not only improves the working environment but also removes the need for heavy concrete foundations or noise insulation rooms.
In short, operators can finally hear the difference — quite literally.
4. Longer Lifespan, Faster Payback
While Roots blowers often last about 10 years (with frequent repairs), RAETTS Maglev Turbo Blowers achieve over 20 years of service life, thanks to contact-free operation and advanced control systems.
Combined with energy savings and low maintenance costs, the total payback is typically within 1–2 years, followed by decades of low-cost, high-efficiency performance.
A Step Toward Greener Operations
Energy-efficient technologies like RAETTS Maglev blowers not only cut operational costs but also contribute to sustainability goals. Reducing electricity usage directly lowers carbon emissions, making this upgrade a powerful step toward eco-friendly wastewater management.
For plant operators, the benefits are clear:
✅ Lower OPEX
✅ Quieter working environment
✅ Reliable long-term performance
✅ Greener, more sustainable operation
Conclusion
Upgrading from traditional Roots blowers to RAETTS Maglev Turbo Blowers is not just a technical improvement — it’s a strategic move toward energy efficiency, reliability, and sustainability.
RAETTS continues to lead the industry in magnetic bearing technology, helping wastewater treatment plants worldwide save power, reduce noise, and operate smarter than ever.
