My Roo 19 didn't have louvers. My Mini Lite has ducted flow, but it also has same vents you show, but not louvers, just an open/close slider. I don't think you'll find any with louvers, unless you replaced the entire AC unit.
Most folks with Roo's plug in their bunk fans and move the air around that way.
