Multistage centrifugal blowers are rotating machines able to increase the pressure of air or gasses, by means of the centrifugal force normally transmitted by an electric motor.
The main components of the Robuschi Multistage Centrifugal Blower product are:
1. Multiple Baffle Rings - Guides airflow smoothly into the eye of the impeller, dramatically reducing inlet passage losses. When combined with the two-dimensional impeller design increases blower efficiency and pressure/vacuum capability.
2. Balance Piston - Negates axial force and reduces pressure on the drive bearings, increases rotor bearing life, and minimizes leakage of compressed gas.
3. Multistage Shrouded Impellers - Two-dimensional shrouded cast aluminum impellers are balanced individually and keyed onto the shaft. On most blowers, the complete assembly is then balanced to achieve smooth operation with the lowest vibration levels in the industry. Rotor assemblies are designed to operate well below the first critical speeds for added reliability.
