Non-Contact Oil Film Bearings

  • 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 Scale Easily.

 

Robust mechanical design scales to larger equipment without redesign issues.

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.


Aerospace-Grade Seals for Oil-Free Air

  • Extremely durable and delivers oil-free air
  • Restricts oil more effectively than other seal types



High Efficiency Aero Stage

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
