A Flexit ventilation unit with its front removed shows the filter, fan and control box inside, mounted on a light blue plinth. Further back, a Stagewheel rotor stands on a dark blue pedestal beneath the curved Flexit canopy, with wooden slats on the left and a larger unit with round duct connections on the right.
