KOA Series
Centrifugal Air Compressors
This type of compressor uses a centrifugal impeller to increase the pressure of the air, resulting in a compressor that is quieter and more efficient.
Kotech compressors provide efficient and reliable operation, as well as reliable and efficient after-sales service.

Why choose a Centrifugal Compressor (Turbo Compressor) for plant air?
A centrifugal air compressor is typically selected when you need large flow, continuous operation, and high efficiency in industrial plants.
Compared with many positive-displacement compressors, the centrifugal (turbo) design can provide stable air delivery with low vibration and a project-friendly packaged layout.
| Selection factor | Centrifugal / Turbo compressor | Typical alternative |
|---|---|---|
| Best use case | Large flow, continuous plant air | General purpose / medium flow |
| Efficiency focus | Strong at large demand ranges | Depends on duty cycle and load profile |
| Maintenance style | Project-based service planning | More frequent wear components (varies) |
How a Centrifugal (Turbo) Compressor Works
A KOA centrifugal unit is typically driven by an electric motor and uses high-speed impellers to convert velocity energy into pressure energy.

KOA Design Highlights for Centrifugal Compressor Reliability
- Titanium alloy impeller; optional anti-corrosion coating
- Five-axis precision machining; 3D back-leaning design
- Splitter blade design for large flow & off-design adaptability
- Horizontal split gearbox for service access
- Tilting pad journal bearing for high-speed stability
- Labyrinth seal (non-contact) for long life & low maintenance
- Inlet Guide Vane (IGV) for smooth adjustment
- High-efficiency scroll design concept
- Siemens PLC + Touch screen; anti-surge protection
long life drainer with low gas consumption (as described on current page).
