A cabinet fan with an open side panel exposes its centrifugal impeller on the Aspirnova Industry stand, next to a roof extract fan with a conical cowl. Both sit on light wood plinths, while a blue wall-mounted heat recovery unit with red and blue arrows hangs on the lime-green wall marked by a large navy "A".
