On a semi-related note... If you are building a dust collector you need to keep the velocity up, not just the CFM. A high velocity keeps the dust & dirt from falling out of the airflow & plugging the pipe. Not so much relevant to a fume extractor though.
Good points. To assure there's no confusion, dust collectors collect and store dust but alow micro particals to escape and become suspended in shop air.. My contraption capture's those micro size particals before they are inhaled.
