Air-Cooling Fan And Intake Vent - Panasonic VL-W1 Series Setup And Maintenance Manual

7-2-4 Air-cooling fan and intake vent

The air-cooling fans are equipped on the controller.
If any dust adhered onto the fans or intake vent may decrease the cooling performance and cause the performance to
degrade, or failure of the laser processing machine.
Clean them regularly according to the usage environment.
„ Effect from deterioration of the fans
Depending on the usage environment, any dust or oil 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 or laser oscillator
will go up, which may cause an error or stoppage of laser radiation. Also, a temperature rise in the housing will foster
deterioration in the internal parts, which may cause the product performance to degrade, or failure.
„ Replacement interval of the fans
• The fan does not rotate, or the rotating speed is low.
