Q How long do Perseus fans last in high-temperature duty?
AService life depends on bearing load, speed, temperature, humidity, vibration, and contamination. Representative Perseus DC fan models list L10 life of 50,000 hours at 40°C, while the Titan 400Hz AC reference model lists L10 life of 13,000 hours at 40°C. For semiconductor or furnace-adjacent duty, review lubricant temperature limit, bearing type, airflow path cleanliness, and the actual chamber-side ambient before using any catalog life value.
