Hi GC peeps, Any Ventilation experts here know where the best place for a in-line duct fan is in a system? I have a 179cfm vortex fan sucking through a CF, pushing it down ~25ft of light with a few slight bends and turns but nothing more than maybe 20degrees. I think that the system could benefit from something like this to help keep the air moving. If that sounds like a good idea, where would it be best installed in the existing system? I figured maybe halfway between the fan and the exit point I had one other question, I was looking to put in an air cooled reflector but currently the system is all 4" ducting, would it hurt much to get a 6"-4" reducer on each end of the reflector and keep the rest of the system at 4"?
