While in cruise flight at FL340; we got an AIR COND FAIL caution light and heard the EMER system come on in the cabin. Immediately following this indication we noted a change in cabin altitude with a sustained cabin climb of approximately 2;000 FPM. This was followed by the CABIN LOW PRES warning indicator within a few minutes.We donned O2 masks and asked ATC to for a descent due to a cabin pressurization issue. In the descent we ran the checklist for both cabin PRES LOW and AIR COND FAIL. While in the decent ATC asked if we wanted to [advise] for the descent; we replied yes. At 10;000 feet.; we advised we would divert and [situation] was over.
[Report narrative contained no additional information.]
Transport flight crew reported a failure of the pressurization system; which necessitated an immediate descent and a diversion to a nearby airport.
