ROTOR SEAL

To achieve the best possible prevention from leakage between exhaust and supply air, the Ostberg Casing design offer multiple options of sealing system.

• For standard applications a brush sealing is installed on the rotor periphery (between the rotor matrix and the casing).
• For improved sealing a second sealing can be installed on the rotor periphery which give a “wrap-around” sealing system. The wrap- around sealing system provide the best possible sealing system to prevent leakage along the rotor periphery.
