A row of compact centrifugal fans with blue impellers and blue hubs set in black square inlet housings, displayed on a glossy blue acrylic plinth. The frame belongs to the Ziehl-Abegg stand, whose blue walls and display furniture appear in the neighbouring shots. The housings show mounting holes and moulded inlet rings.
