Whenever the heroes enter a Mad Scientist Laboratory in an unconventional way, they'll experience slight air draft coming from inside (or the other way around). Same thing happens whenever a science-y MacGuffin is opened with a slight hiss. In Real Life, keeping some 1.2 atmospheric pressures inside is part of airtight sealing of laboratories against dust and other dirt from the outside: even if dust manages to find a crack in the sealing, it'll be blown right out by the pressure difference. On the other hand, labs dealing with dangerous micro-organisms (bio-hazard levels 3 and 4) require the lab to maintain a negative pressure difference to suck whatever nastiness is developed there right back inside. This trope covers both cases.

In Virtue's Last Reward, a manual in the Pressure Exchange Chamber states that Rhizome-9 keeps its atmospheric pressure higher than its surroundings to keep out the Radical-6 virus. This is only partly true; the atmospheric pressure is higher inside the facility than outside because it's on the moon. | |

The X-Wing Series of books has the Imperial labs on Coruscant that were developing the Krytos Virus designed this way. In case of a containment leak and someone came in, the air would flow in instead of out, preventing the virus from leaving the building. | |

When the door to Nicodemus' study opens in The Secret of NIMH, Mrs. Brisby is met with a blast of wind and a blinding light. Not sure why that would happen, except that it looks cool. | |
