A line mechanic reports about inlet and extract vent blower ECAM faults occurring on an A319 aircraft during a flight turnaround. Two equipment cooling air filters in the electrical equipment (east/east) bay were found completely clogged; preventing effective cooling of associated avionics equipment.

Narrative:
During [flight] turn; crew sent two write-ups indicating extract vent faults. Dayshift avionic's technician was also getting inlet and extract blower faults at the gate during his evaluation. My first suspicion is the equipment cooling air filters. One is flat and the other is round; both are located in main electronic equipment (east/east) bay. A check of each filter shows both are completely clogged. I was unable to see direct sunlight through either one. The flat one was oil canned due to 'no' air flow. In my opinion; the ability to effectively cool the associated avionics equipment was completely compromised. Also; the equipment cooling blowers may have lost significant service life. An 'on-ground delay; cancellation; or in-flight smoke could have been a near future incident.
