Reliability and Efficiency Without the Noise
In wastewater treatment and industrial environments, noise can be both a nuisance to neighbors, but more importantly, it’s a safety concern, a regulatory issue, and a barrier to efficient plant operation.
Inovair blowers are engineered to deliver industry-leading airflow, efficiency, and durability while maintaining low sound levels across the full operating range. The result: Running at less than 85 dBa, Inovair blower packages are quieter, safer, and provide a more comfortable environment for operators—without sacrificing performance.
WHY LOW NOISE MATTERS
- OPERATOR SAFETY & COMFORT
Reduced noise levels help minimize operator fatigue and support compliance with workplace safety standards. - SIMPLIFIED INSTALLATION
Lower sound output reduces the need for extensive acoustic enclosures or retrofitted sound mitigation. - COMMUNITY & ENVIRONMENTAL IMPACT
For plants located near residential or commercial zones, quieter operation helps reduce offsite noise concerns and complaints.
LOW NOISE ACROSS THE FULL OPERATING RANGE
Under 85dBa, which is below the strictest NIOSH levels, allows for 8hr in room without ear protection. It also meets most noise ordinances when the blower package is installed outdoors.
Unlike traditional blower technologies that generate increased noise at partial load or during frequent cycling, Inovair systems maintain stable acoustic performance whether operating at low demand, peak capacity, or during frequent start-stop cycles.
This consistency is critical for facilities with:
✔ Variable flow requirements
✔ Frequent cycling (start/stop conditions)
✔ 24/7 operation with rotating staff

HOW INOVAIR DELIVERS LOW NOISE
- PRECISION ENGINEERED AIRFLOW
Smooth, non-pulsating airflow reduces tonal noise and vibration commonly associated with positive displacement systems. - BALANCED ROTATING ASSEMBLIES
High-speed components are dynamically balanced to minimize vibration and mechanical noise. - INTEGRATED SYSTEM DESIGN
From inlet to discharge, every component is designed to reduce turbulence, resonance, and acoustic inefficiencies. - NO CONTACT, NO WEAR SURFACES
Oil-film bearing technology eliminates mechanical contact during operation—reducing both noise and long-term degradation.
REAL-WORLD PERFORMANCE: COATESVILLE, PA WASTEWATER TREATMENT PLANT
Challenge: Modernize aeration system while improving operator experience and minimizing noise in an active facility.
Solution: Installation of multiple Inovair IM-Series blowers integrated with advanced control systems.
Result:
Solution: Installation of multiple Inovair IM-Series blowers integrated with advanced control systems.
Result:
- Noticeably quieter operation compared to legacy equipment
- Improved working conditions for plant personnel
- Reduced need for additional sound mitigation infrastructure
“The reduction in noise was immediately noticeable. Operators can communicate more easily on the floor, and overall working conditions have improved significantly.”
MUNICIPAL UPGRADE – MULTI-BLOWER INSTALLATION
Challenge: Replace aging blower system with a solution that could handle variable demand without increasing noise levels.
Solution: Inovair blowers with master control integration and optimized operating ranges.
Result:
Solution: Inovair blowers with master control integration and optimized operating ranges.
Result:
- Consistent low noise across varying loads
- No increase in facility noise despite higher capacity
- Enhanced operator satisfaction and usability
“Even with increased airflow capacity, the facility is quieter than before. That’s something we didn’t expect—but immediately appreciated.”
FREQUENTLY ASKED QUESTIONS
How do Inovair blowers compare to positive displacement blowers in noise?
Centrifugal technology produces smoother airflow with less pulsation, resulting in lower tonal noise and vibration.
Do I still need an acoustic enclosure?
Inovair blower packages come with an acoustic enclosure, but the technology itself is what keeps the baseline noise level lower than other technologies. In most cases, installing an Inovair blower package reduces or eliminates the need for additional sound mitigation, depending on site requirements.
Does noise increase at partial load?
No—Inovair systems maintain stable acoustic performance across a wide operating range.
