Janus, I'm not sure if I understood your question correctly, but I'll try to answer by describing the ventilation system.
Both rooms have separate ventilation circuits, each on with its own motor and ducts. The studio system has a silencer after the motor.
The system is designed to force the air into the room. That would keep the pressure inside the room slightly higher, which should prevent the dust from entering through doors. Another duct takes the air out of the room, but it is a free flow, with no motors, only a silencer.
Hope this answers your question.
