Non-Contact Oil Film Bearings
This bearing design ensures long service life and consistent uptime by minimizing mechanical wear and maintaining stable operation across a wide range of conditions.
- High-Stability, High-Load Hydrodynamic Support
- Two hydrodynamic oil films (inner & outer)
- Each film creates its own hydrodynamic wedge
- Provides stable, non-contact rotor support
- Dual-film damping system
- Two 'shock absorbers' for rotor stability
- Reduces vibration and rotor whirl
- Handles pressure swings and surges
Why Oil Film Bearings?
Oil Film Bearings Are Most Durable.
Virtually unlimited service life, even in demanding start-stop applications.
Mechanical vs. Electronics.
Mechanical systems are inherently more reliable, easier to maintain, and as efficient as any electronics-heavy bearing systems.
Oil Film Bearings Scale Easily.
Robust mechanical design scales to larger equipment without redesign issues.
Aerospace-Grade Seals for Oil-Free Air
Designed for maximum sealing effectiveness, these aerospace-grade seals restrict oil carryover more efficiently than conventional designs while maintaining proven, long-term reliability.
- Extremely durable and delivers oil-free air
- Restricts oil more effectively than other seal types
High Efficiency Aero Stage
Inovair's high-efficiency aero stage is engineered as a complete system, where impeller design, volute geometry, and operating controls work together to maximize performance and minimize energy loss.
Impeller
- Over 70+ impeller options available, with matched volutes
- Two (2) in-house Aero Engineers
- PTC 13 testing to verify efficiency
- Optimized blade geometry increases aerodynamic efficiency
- Backward-curved blades reduce losses and improve pressure generation
- Proper tip speed and inlet eye sizing lower shock losses and turbulence
- Up to 60% turndown
- Standard VFD adjusts blower output automatically, optimizing system efficiency
Volute
- Smooth diffuser and volute transitions convert velocity into pressure efficiently.
- Proper tongue geometry minimizes recirculation and pulsation losses.
- Increasing uniformity of flow distribution lowers energy consumption.
- Delivers promised performance without wasted energy.
Process and Controls
- DO / ORP Control – Optimizes oxygen delivery, stabilizes treatment, and reduces energy use
- Ammonia Control (ABAC) – Aligns airflow with load, alsolowering operating cost
- Local Control Panel (LCP) – Precise single-blower control with automatic compensation for process changes
- Master Control Panel (MCP) – Coordinates multiple blowers for maximum efficiency, balance, and SCADA integration
- Remote or local VFD mounting options
- All off-the-shelf components for ease of integration and maintenance
Performance Across All Applications
