The TV-A300 handles the rooms ductwork never reached: a floor-standing tower that draws air through a wrap-around perforated intake, passes it through coarse, fine and carbon stages, and returns it through a top outlet ring that mixes without draughts.
Filter doors open with a coin, stages replace independently, and the control face is a single dial with a discreet status ring — nothing for a lobby to misread. Casters lock for permanent placement or roll for event layouts.
