What causes excessive levels of ozone in an air system?

1. Insufficient air flow

2. Excessive air flow

3. Insufficient secondary air flow

4. Excessive primary air flow

The correct answer is: Insufficient air flow

Excessive levels of ozone in an air system can indeed be attributed to insufficient airflow. When airflow is inadequate, it can lead to incomplete combustion of the gases involved, which can result in the production of ozone as a byproduct. Additionally, systems that rely on electrical components, such as ozone generators, may not effectively disperse ozone if the airflow is too low, allowing it to accumulate. In technical terms, ozone is often produced in environments where the air quality is poor due to the presence of pollutants and insufficient mixing or circulation within the air system. Therefore, maintaining proper airflow is critical to prevent the buildup of ozone, ensuring a balanced environment that promotes effective air quality and safety.
