Axial PC fan MDE series

long-life axial fans utilize a brushless motor and have an expected life of 100,000 hours. A stall alarm comes standard. Long Life Models - 100,000 hours 12 VDC, 24 VDC or 48 VDC Stall Alarm Fan Kits available Long Life Axial Fans These axial fans have an expected life of 100,000 hours (about 11 years). They reduce the increase in bearing temperature, inhibit grease deterioration and improve vibration resistance and shock resistance through bearing enlargement. They also increase the life of circuits and couplers and reduce failure rate. They are designed based on the concept of initial failure so that random failure and wear-out failure will not occur, allowing for 100,000 hours of continuous operation or more (survival rate of 90% or higher). Long-life axial fans have an expected life of 100,000 hours, so the number of cooling fans that need replacing is decreased compared to conventional models. Stall Alarm Type If a cooling fan is left stopped, the internal temperature increases which has an effect on the equipment. The Stall Alarm type fans output an alarm when the fan stops. This allows quick detection of defective stops to allow the cooling fan to be replaced.
