Dayton compact air curtains act as a thermal barrier in transoms, drive-through windows and other similar openings to prevent dust, fumes and insects from entering the facilities. These units feature a blower with totally enclosed motor assembly for an optimal airflow. They are placed above entrances, such as doorways or loading bays to create a temperature barrier for unhampered vision or traffic through the opening. Choose from a wide range of these compact air curtains, available in 1/8 and 1/10 HP motor ratings.
