7-2-4 Air-cooling fan
The air-cooling fan cools the laser oscillator and internal power circuit. This product has four fans (intake) on the head and
two fans (intake) on the controller. The fans rotate all the time during power on.
„
Effect from deterioration
Depending on the usage environment, any dust or contamination adhered onto the fan may impair air flow rate of the fan or
even stop the rotation of the fan. When the cool performance decreases, the temperature in the electric circuit will go up,
which may cause an error or stoppage of the product. Also, a temperature rise in the housing will foster deterioration in the
internal parts, which may cause the marking performance to degrade, or failure of the equipment.
„
Replacement interval
