<p>The ventilator and air distribution device is for cattle stalls, having a slit form air inlet aperture mounted in the ceiling and directed downwards into the room. A parallel regulator plate adjusts the width of the air inlet aperture edges. The regulator plate (4) is mounted or hung from parallel pendulum arms of equal length. The positioning of the plate relative to the air inlet is controlled by a push or pull device which operates in the same plane as the regulator plate.</p> |
