Max Height

Ambient air curtains are designed to prevent heat loss at a door entrance, but to not provide additional heating. To be fully effective as thermal barriers they should cover the full width of the door, otherwise cold air may penetrate at the edges. If a door opening is double width, then a suitably sized (double width) air curtain will be required. If the unit is to be mounted significantly above a doorway, or if the door opening is unusually tall, then a more powerful unit is likely to be required to maintain the airflow.
