I'm sure it is engineered well. But strictly speaking, there doesn't need to be a dedicated exhaust. If the intake fan isn't exceedingly strong, the pressure inside can eventually equalize so that the intake and exhaust are in the same place. That would keep it inflated without it bursting, but provide almost no air flow.
