You still need a way to get air in the duct. Either this: https://www.gmptools.com/innerduct-pressurization-test-kit/ <https://www.gmptools.com/innerduct-pressurization-test-kit/> or this https://www.gmptools.com/line-blowing/ <https://www.gmptools.com/line-blowing/> to attach to the compressor. Neither tool is very expensive (relative to the stupid price of most things fiber)
