I have an application (a tube with parts in it) which needs a certain static pressure in it in order to contain a sustainable air flow. Unfortunately the fan I wanted to use in a push-configuration is not able to create this pressure. Thus I thought that I could install another fan with a higher cfm at the end of the tube (in pull-configuration), and thereby increasing the static pressure? Would that be useful, or is there another way to increase the static pressure in the tube? Schematic is:
Neither F1 or F2 are able to provide the necessary static pressure alone.
