Heres how to calculate fan horsepower when you have change in cfm… Fan Law 101: Why 50% Airflow Doesn’t Mean 50% Power Ever wonder what really happens to power consumption when you reduce a fan's airflow? Here’s the formula: (HP₂ / HP₁) = (CFM₂ / CFM₁)³ This is one of the most important — and most overlooked — relationships in HVAC design. Take this simple example: If you reduce a blower from 300 CFM to 150 CFM, you’re cutting the airflow in half. But the horsepower requirement doesn’t just drop
