On the red-lit counter of the Ergovent stand sits a black plenum box with two orange-sealed round spigots, covered by a stone-look plate with narrow linear slots for a concealed diffuser. A white round air valve with an orange seal stands in the foreground, while visitors talk at the back of the stand.
