What is the purpose of the airflow indicator on a ducted system?

The purpose of the airflow indicator on a ducted system is to monitor and balance the airflow throughout the ducts. This tool is vital for ensuring that the air distribution in the system is efficient and effective. Proper airflow is critical for maintaining the desired temperature and comfort levels in different areas of a building.

By using an airflow indicator, technicians can identify areas within the duct system that may have too much or too little airflow, enabling them to make adjustments as necessary. This not only contributes to the overall comfort of the occupants but also improves the efficiency of the heating or cooling system by ensuring that air is distributed evenly. This prevents issues such as hot or cold spots and can help in reducing energy consumption by optimizing the system’s performance.

Other options, while they may seem relevant, do not align with the primary function of an airflow indicator. For instance, generating air pressure is not a role of the indicator itself; its job is more about measuring and balancing what is already present. Detecting leaks is also not a direct function of an airflow indicator, although knowing airflow patterns can help indicate potential issues. Measuring temperature changes is outside the scope of an airflow indicator’s function, as its focus is solely on airflow rather than temperature.
