booster fans in 6" metal ducts
Does anyone have any actual experience trying to increase air flow in a 6" hard metal duct using booster fans? My dining room gets air from a 25' long 6" duct, but it only as two bends, one at the start above the master duct and the other coming up through the wall. The actual gas blower is 4 tons and should be enough, but the force at the end is weak. Were you able to get a better air flow?
willing to look at my duct diagram and suggest?
Would anyone be willing to look at a fax of the diagram of my ductwork and suggest where I might try to add booster fans, maybe spider cage fans or whatever to get more airflow on the other side of my house? I just can not find any hvac tech here who is willing to take on this kind of trial and error work. I can add the fans, but I need a pro to tell me what size and type to add and where.
