Removing the cut-off plate from the blower assembly will primarily affect the airflow dynamics within the system. The cut-off plate serves to regulate and direct the flow of air generated by the blower. By increasing the effective area through which the air can flow, eliminating the cut-off plate allows for less restriction during operation.

This means that more air can pass through the blower assembly, leading to an increase in airflow. While there may be other factors that contribute to the overall airflow of the system, the direct consequence of removing the cut-off plate is that it removes a point of restriction, enhancing the blower's ability to move air more freely. Consequently, the performance of the blower will be improved concerning its capacity to deliver a greater volume of air, aligning with the notion that increased airflow is a probable outcome of this modification.

In systems where airflow is crucial for efficiency and performance—such as in air conditioning—the implications of increased airflow can significantly affect overall system performance.
