[Amps] Layout of tube

[MIKE DURKIN]

I seen some one ask what the tube is -- its a GS-35B that im going to install ... i have a fan (original) thats 89CFM, im planning on adding 2 more- one to presurize and the other to assist on the exaust, the new fans are 98.2CFM at .24"

 

Also found this about parallel and series cfm of fans http://www.comairrotron.com/airflow_note.shtml
