Evaporative Cooler Size Calculator
FAQs
How do I know what size evaporative cooler I need? The size of the evaporative cooler you need depends on the square footage of the area you want to cool, the local climate conditions, and the desired indoor temperature. A general estimate is to have around 20-25 CFM (cubic feet per minute) of airflow per square foot of the cooled space.
What size swamp cooler do I need for 2000 square feet? For 2000 square feet, you might need an evaporative cooler with an estimated capacity of around 40,000 to 50,000 CFM.
How do I know the CFM of my swamp cooler? You can usually find the CFM rating on the evaporative cooler’s label or in the product specifications provided by the manufacturer.
What is CFM for evaporative cooler? CFM stands for cubic feet per minute and refers to the amount of air that an evaporative cooler can move in a minute. It indicates the cooling capacity and how effectively the cooler can replace warm indoor air with cooler outdoor air.
