Italian term or phrase: risucchio del fuoco
Could this be "backdraft"?

Full sentence for context:

"Il blocco del ventilatore di ricircolo deve determinare l’istantanea chiusura delle serrande per evitare che la maggiore depressione a valle del filtro elettrostatico, rispetto alle camere di combustione, determini il risucchio del fuoco nei condotti."

English translation:fire backdraft
Explanation:
Backdraft is created when the oxygen in the room is consumed (the room is "starved" of oxygen). This creates a vacuum and any additional oxygen is introduced into the room causes an explosion
The link about the "backdraft drink" gives a good down to earth idea of how the vacuum is created within a glass.
Backdraft is often confused with "flashover" which although it still results into sudden ignition of a whole room, is caused by different agents. Check out the first link also, it is about "rollover" which may precede flashover.
