Cold Planer Cutting Chamber Ventilation

A cold planer and method for ventilating the cold planer. The cold planer comprises a frame, a hood, a milling drum and a ventilation system. The hood is disposed under the frame and defines a cutting chamber. A milling drum is disposed inside the cutting chamber under the hood. The ventilation system comprises a cutting chamber port, a boost fan, a settling box and a main fan. The cutting chamber port extends through the hood. The boost fan is configured to generate a siphon that draws airflow from inside the cutting chamber through the cutting chamber port. The settling box is configured to cause particles to drop out of airflow. The settling box is in fluid communication with the cutting chamber port. The main fan is configured to draw airflow from the settling box and a region in front of the hood and vent it away from the cold planer.
