1. A centrifugal compressor, comprising:
a housing having a first inlet and a second inlet, the housing forming a plenum chamber with an outlet spaced apart from the first inlet and the second inlet
a shaft disposed in the plenum chamber;
an impeller coupled to the shaft and located inside the housing downstream of the plenum chamber, the impeller arranged to increase gas pressure as process gas flows past the impeller; and
a first septum and a second septum disposed in the plenum chamber, the first septum and the second septum having a body extending from a first end coupled to the housing into the plenum chamber towards the shaft, the body terminating at a second end with a first portion secured to the housing and a second portion disposed in the outlet.
