A controller of an airflow control system is configured to instruct a blower to output an airflow, to instruct an airflow control assembly to close a door upon detection of a first threshold pressure within the interior of the cab, and to measure a depressurization time between the detection of the first threshold pressure and detection of a second threshold pressure, less than the first threshold pressure, which is used to determine a restriction factor. The controller is configured to determine an airflow rate into the interior of the cab based at least in part on the restriction factor and a pressure within the interior of the cab. The controller is further configured to instruct the blower to adjust the airflow, instruct the airflow control assembly to adjust a position of the door, or a combination thereof based at least in part on the airflow rate.
