I am wanting to create a moderate amount of suction with a blower fan and I am trying to figure out the relationship between static pressure and airflow measured in CFM. Does higher CFM necessarily give you greater static pressure? I'm thinking I need between 150 to 200 CFM to get around 1 inch of static pressure, but that is a wild guess. When I search online for such a fan I find either a computer cooling fan which is not enough power or I get an industrial type blower fan that is way too powerful. I can't seem to find something in between.
