Which specifications describe the box fan's power supply and airflow rating?

• A. 230 V with 3200 cfm
• B. 120 V with 3200 cfm
• C. 115 V with 3200 cfm
• D. 115 V with 1600 cfm

Answer: (C)

Box fans are defined by two key specs: the electrical power supply it’s intended to use (voltage) and the amount of air it moves (airflow) measured in cubic feet per minute. The voltage tells you what outlet the fan is designed for, and the airflow rating tells you how much air the fan can push through per minute. The shown combination of 115 V with 3200 cfm matches a common U.S. household voltage and a strong airflow figure for a box fan, making it the best fit for this model. The other options either switch to a different regional voltage or lower the airflow, which wouldn’t align with the same fan’s rated performance.
