By inverter I think you mean VFD? Did it come with the impeller or you have to find one? With a VFD you have a choice of how fast to run it but generally a 15" impeller at 60hz will be fine using 6" pipe but 7" would be better if you can find it and running it faster use 8" pipe. Using bags it needs to be outside the working place because all bags leak despite what anyone may tell you. A fan curve is not necessary as it won't change anything because you already have the impeller and it will work. If you were sourcing a fan that might be a different story.
