A wall flange is the easiest and best solution for connecting your exhaust air system to an opening in the wall. The connection between the flange and the exhaust pipe prevents exhaust air from escaping inside. While a pipe that is simply inserted into the wall is easily dislodged by vibration and airflow, it remains firmly secured by the wall clamp.
