What is the role of an air mover in the drying process?

The role of an air mover in the drying process is primarily to circulate air and promote evaporation of moisture from wet surfaces. Air movers are designed to enhance air movement, which is crucial in the drying process because increased airflow helps to evaporate moisture more effectively. By directing airflow over wet materials, air movers accelerate the rate at which water evaporates, thereby reducing drying times and helping to prevent secondary damage, such as mold growth.

In contrast, the other choices do not accurately describe the function of an air mover. For instance, creating a thermal barrier around the affected area would neither facilitate moisture evaporation nor is it a typical role of an air mover. Increasing humidity in the environment would be counterproductive in a drying situation, as it would inhibit the evaporation process rather than promote it. Additionally, while air movers may be present during restoration work, they do not specifically assist with chemical applications; rather, their main focus is on creating airflow for effective drying.
