CFM per Ton Checker
Airflow per ton of cooling against the 350–450 CFM/ton commissioning window.
400 CFM/ton (190 L/s per ton) is the design centre. Deliberately running 350 squeezes out more latent capacity in muggy climates.

CFM per Ton Checker is a free cfm per ton for HVAC designers, technicians and energy auditors — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About CFM per Ton Checker
Airflow per ton of cooling against the 350–450 CFM/ton commissioning window. The calculation implements CFM/ton = airflow ÷ tons; dry climates 450, humid 350 (ACCA Manual S; manufacturer application data). 400 CFM/ton (190 L/s per ton) is the design centre. Deliberately running 350 squeezes out more latent capacity in muggy climates.
