US Patent 12117114 Cleanroom wall passthrough

A passthrough for a barrier separating a first space from a second space includes a housing mounted to an opening that extends through the barrier. First and second doors selectively block the first and second spaces, respectively, from the opening. A frame is disposed within the housing and has first and second apertures configured to receive sealing blocks. When the passthrough is in a first state, sealing blocks seal the first and second apertures. When the passthrough is in a second state, a fluid conduit passes through the first and second apertures and sealing blocks seal the space between the first and second apertures, respectively, and the conduit.
