Question: 1 / 400

If the cut-off plate is removed from a blower assembly, how would this affect blower performance?

Increase airflow

Reduce airflow

Removing the cut-off plate from a blower assembly will reduce airflow. The cut-off plate serves a critical function in directing and managing the airflow within the blower assembly. It helps to create a controlled path for the air, ensuring that it moves efficiently through the blower and into the system. By removing this component, the airflow becomes less directed and more turbulent, which leads to inefficiencies in how air is moved.

Without the cut-off plate, there is a higher likelihood of airflow being disrupted, which can cause a drop in overall performance. This may also lead to various issues, such as a decrease in air pressure and potential imbalances within the system, affecting the overall efficiency of the air conditioning or heating system. Thus, the correct understanding is that the removal of the cut-off plate fundamentally impacts how effectively the blower can move air, leading to a reduction in airflow.
