Vent Clear heat recovery units marked 'powered by SpiroFlex' stand in front of a wide screen wall carrying a recuperation slogan. Black insulated duct elbows and plenum fittings sit on top of the units, a white SpiroFlex panel with louvred grilles stands on the left, and the stand is crowded with visitors in conversation.
