💨 0.10 to 0.50 CFM/Bushel, Shedd Curves Static Pressure & Axial/Centrifugal HP

Grain Bin Aeration Fan & Static Pressure Calculator

Calculate grain bin aeration and cooling fans: calculate required airflow (0.10 to 0.50 CFM per bushel), static resistance pressure drop through deep grain beds (Shedd Curves in Inches of Water Column - In WC), axial vs inline centrifugal fan horsepower, and equipment margins.
