400 CFM per ton of air conditioning: The higher CFM is required to remove the sensible heat from the environment. However, if you have an environment that has high humidity then 350 CFM per ton is better. At the lower CFM the coil is colder and the air spends more time on the coil and increases dehumidification.
How many CFM are in a ton of cooling?
1 ton of cooling is equal to 400 cubic feet of air per minute. 2 ton of cooling is 800 cfm and so on. So a 4 ton unit will have 1600 cubic feet of air passing through the system every minute.
How many CFM is a 3 ton AC?
1200 CFM
What is the CFM of a 5 ton AC unit?
2,000 cfm
How many CFM is a 7.5 ton?
Most packaged air conditioning equipment is designed for, and rated at, 400 CFM per ton. Typically, a 7.5 ton unit will be selected with a drive package that causes it to deliver 3,000 CFM against whatever resistance the ductwork and grilles offer.
