ABSTRACT:
A high pressure centrifugal blower having vertically split casing and aluminum or steel impellers mounted on a common shaft housed within the casing, and at least two oil-enclosing bearing housings to rotatably support the rotors, where an integral gearbox is formed as part of the blower casing so as to increase the impeller rotational speed to achieve higher pressure, and axial impeller eye seals are utilized to reduce the clearance and enhance reliability for higher pressure applications.
