In another ASHRAE project RP-1344 study on airlocks, it was found that airlock is possibly the most effective mechanism to minimize particle migration not only during door operation (dynamic conditions) but also in the door-closed situation (static conditions) since a time delay between two doors could allow the contaminated air entered the airlock space (after the first door operation) to be replaced by the clean supply air.
