- Multistage centrifugal impellersTwo-dimensional aluminum impellers are individually and collectively balanced for exceptionally smooth operation, low vibration and high reliability.
- Robust housingPrecisely machined cast-iron housing, or aluminum on smaller models, provides high mechanical strength and long service life.
- Balance pistonA dedicated balance piston compensates for impeller axial forces and reduces bearing load, significantly extending bearing service life.
- Labyrinth sealsNon-contact, wear-free labyrinth seals provide long service life and minimal maintenance requirements in air or gas applications.
- Flexible couplingA precisely aligned flexible coupling transfers power efficiently from the motor to the blower and reduces bearing loads.

Benefits
Multistage impellers for stable operation
Precisely balanced two-dimensional impellers reduce vibration and enable exceptionally smooth operation and high system reliability.
Long component service life
An advanced design with a balance piston reduces axial forces on the bearings and extends the service life of critical blower components.
Minimal maintenance
Non-contact, wear-free labyrinth seals and robust construction reduce maintenance requirements and ensure reliable long-term operation.
Many configurations and drive options
Direct drive, belt transmission or gearbox options allow the blower to be adapted to specific process requirements.
Wide range of industrial applications
Robox Multistage blowers are used in wastewater treatment, industrial processes, pneumatic conveying and many other applications with high airflow or gas-flow requirements.
