Air Dampening

When the door opens to quick the air in the chamber will be compressed because of the four small holes (at the moving part in the chamber), the airflow through the holes will not be enough and the door will be smooth to open and close. The most of the dampening will be hidden in the frame and wall. I know that there are some small sealing and screws missing but i did not have the time to make them now.
