The present disclosure provides advantageous rotary interfaces for fluid assemblies (e.g., rotary interfaces for fluid flow in bioreactor applications), and related methods of fabrication and use. More particularly, the present disclosure provides improved rotary interfaces for fluid flow through porous impellers for filtration and/or sparging for fluid assemblies (e.g., bioreactor applications), and related methods of fabrication and use. Disclosed herein is a fluid assembly (e.g., bioreactor) that includes a porous impeller which is in fluid communication with a hollow shaft that can be used to transport a reaction fluid to an external storage tank or the like. The fluid assembly/bioreactor can include a coupling mechanism that transmits rotary motion from a motor to a primary shaft and then to a hollow secondary shaft, while at the same time permitting removal of a filtrate from the fluid assembly or bioreactor via the hollow secondary shaft and a porous impeller.
