# how to calculate osepa fan efficiency

### Codes & Standards

inch fan has a greater total efficiency (66% vs. 60%) and a higher FEG (71 vs. 63). So how can the fan with a higher efficiency consume more than twice the power? First, the FEG is based on fan total efficiency and fan total pressure. Total pressure is used because it is a measure of the total energy imparted to the air.
