How to Determine Over-Amperage on Pulley Size Change?

[QUOTE="Haotranphotomask, post: 6821385, member: 730519"] We have a tool that requires 1300 CFM of exhaust that was previously tied to another exhaust system. They were running into problem with that system, so they decided to move that tool's exhaust trunk to the fans (the fans in this thread, one of them is a spare) that are abandoned in place. The system that was previously tied to these fans are no longer in operation and the tie-in trunk was capped for the tie in of the new tool. The tool itself has about 11 exhaust lines, all tied into an 8" trunk. This trunk has about 200 ft of piping and 12 elbows. Then it's expanded to a 12" trunk (about 20 ft with 4 elbows). Then it's reduced to the inlet of the fans. The discharge side is pretty much just a straight 15ft 12" line. [/QUOTE]
