1. Return air is through side opposite motor (left side) for one side return (worst case).
2. Airflows above 1800 CFM (50.97 m
3
/min) require either return from two sides or one side plus bottom
3. Airflows expressed in standard cubic feet per minute (CFM) and in cubic meters per minute (m
3
/min).
