BORA SERIES – BLOWERS
The Bora three-lobe rotor is the evolution of the classic bi-lobe design, shaped like an “eight”. This Bora design ensures higher bending stiffness, and lower pulsation amplitude that consequently reduces vibration. The economic advantage in the bearing life is appreciable. The compressor noise is remarkably decreased as well.
The synchro-gears are case hardened and tempered. Gears are accurately ground to ensure optimal timing. The “long addendum” in-volute design gives maximum efficiency with virtually silent mechanical operation. This Bora design allows the vacuum boosters to be installed without a sound canopy.
