Three centrifugal fans are mounted on posts along an aluminium rail with labels such as "R3G 225", including a black impeller, a square-framed fan and a green scroll-housing blower. A pillar reads "Commercial Ventilation / Ventilazione industriale", and visitors look at the products on the ebm-papst stand.
