A transparent cylinder with a red-lit ring advertises a "challenge" with prizes on the Airvance Group stand. Next to it, the Cairox house shows diffuser finishes under "Breathe elegance", while inside the house an R-Aqua screen and outdoor unit are on display, with groups of visitors gathered at the stand edge.
