Narrative:

Heavy vibration followed by strong electrical fumes. Donned oxygen and completed smoke and fume qrc. Declared emergency with center and started divert and descent. Shortly thereafter; got ECAM warning. Vent blower fault. Completed ECAM for vent blower fault procedure. Within a couple of mins; got extract vent fault ECAM. Again; completed ECAM procedures. Fumes dissipated shortly thereafter; and crew; along with inputs from dispatch and maintenance; made the decision to divert to ZZZ. Flight landed uneventfully. Taxied to gate. CRM included flight attendants; deadheading A320 captain; maintenance; and dispatch. Callback conversation with reporter revealed the following information: it was determined by maintenance that the extract fan had failed; causing the fumes and vibration. The procedures provided were successful in stopping the fumes because they include taking power away from the fan. No circuit breakers activated.

Title: AN A319 CREW EXPERIENCES VIBRATION AND ELECTRICAL FUMES. OXYGEN IS USED; DSCNT MADE; AND EMER DECLARED FOLLOWED BY DIVERSION TO THE NEAREST SUITABLE ARPT.

Narrative: HVY VIBRATION FOLLOWED BY STRONG ELECTRICAL FUMES. DONNED OXYGEN AND COMPLETED SMOKE AND FUME QRC. DECLARED EMER WITH CTR AND STARTED DIVERT AND DSCNT. SHORTLY THEREAFTER; GOT ECAM WARNING. VENT BLOWER FAULT. COMPLETED ECAM FOR VENT BLOWER FAULT PROC. WITHIN A COUPLE OF MINS; GOT EXTRACT VENT FAULT ECAM. AGAIN; COMPLETED ECAM PROCS. FUMES DISSIPATED SHORTLY THEREAFTER; AND CREW; ALONG WITH INPUTS FROM DISPATCH AND MAINT; MADE THE DECISION TO DIVERT TO ZZZ. FLT LANDED UNEVENTFULLY. TAXIED TO GATE. CRM INCLUDED FLT ATTENDANTS; DEADHEADING A320 CAPT; MAINT; AND DISPATCH. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: IT WAS DETERMINED BY MAINT THAT THE EXTRACT FAN HAD FAILED; CAUSING THE FUMES AND VIBRATION. THE PROCS PROVIDED WERE SUCCESSFUL IN STOPPING THE FUMES BECAUSE THEY INCLUDE TAKING PWR AWAY FROM THE FAN. NO CIRCUIT BREAKERS ACTIVATED.
