for heat pump and high sensible heat applications, and 350 cfm per ton of cooling for high latent heat applications.
How many CFM are in a ton?
The airflow is measured in cubic feet per minute (CFM). 350 to 400 CFM per ton of cooling is required for proper air conditioning system operation.
How many CFM is a 3 ton?
A 3-ton heat pump has approximately 1200 CFM of air flow.
How many CFM is a 5 ton unit?
A 5-ton system should have have 2,000 cfm, a 6-ton system should have 2,400 cfm, and so on and son. Measuring how much airflow measurements deviate from that math is a quick way to diagnose airflow issues in a residential duct system.
Why is 400 CFM a ton?
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 is a 2 ton unit?
For optimum performance, most manufacturers recommend that 400 cfm per ton of air conditioning should be used. For example, a 2-ton system should have 800 cfm of air moving through the evaporator coil.
How do you convert CFM to square feet?
Divide the home’s square feet by required system airflow to find average cfm per square foot. Here’s an example: Required system airflow is 1200 cfm. The square feet of the home is 2000. Divide 1200 cfm by 2000 square feet.
How much CFM do I need?
How do you calculate CFM for a range hood? Determine the volume of your kitchen. Multiply that number by 15, the standard number of times a range hood should exchange all the air in your kitchen per hour. Divide that number by 60 to get the minimum cubic feet per minute for your hood.
What size ductwork do I need for a 5 ton unit?
Using this approach, two 20-in. x 25-in. return grilles will be the right choice for a five-ton HVAC system in order to actually deliver 2,000 cfm back to the blower without causing the return to hemorrhage.
How many CFM is a 4 inch duct?
Reviewing the chart, a 4” pipe will convey 395 CFM at 4500 FPM. This means that a 4” pick-up on a machine will use 395 CFM from the filtering system; or, if you know that a machine will require approximately 400 CFM to remove the waste, you should use a 4” pipe for that purpose.
