Predict new airflow, static pressure and horsepower when you change fan speed, using the fan affinity laws.
Airflow changes in direct proportion to fan speed, pressure with the square, and power with the cube. A 10% speed increase means about 33% more horsepower. Check the motor's rated horsepower and amps before speeding up a fan.
Estimates based on your inputs. Always verify against the manufacturer's data and the codes that apply where you work.
