To facilitate a longer product life of a fan, Sanyo Denki recommends a few different options. The best way to extend product life is to decrease the ambient temperature experienced by the fan. This can be done by relocating fans to the intake side of the device, reducing the temperature rise requirements of the system, or moving a device into a lower ambient temperature environment. Another good way to increase the devices life is to use a Sanyo Denki long life series fan. Long life fans are specifically designed to operate over an extended period of time exceeding 100,000 hours of continuous usage. The final method to extend life is to turn off the fan or reduce fan speed when it is not needed. PWM control allows the user to slow down or stop a fan to conserve the bearings to prevent unnecessary usage.
