This is an adapter for connecting a 4 inch flexible duct to an AC Infinity CLOUDLINE LITE A6 6 inch inline fan. It serves the same function as this commercially available adapter. I coated the adapter with a resin clear coat to make it completely air tight (probably overkill though).
I'm using this to provide continuous ventilation for a Glowforge Plus (the built in fan shuts off between jobs) in combination with my 4 Inch Duct to Window Kit Adapter.
Note that reducing the duct radius from 6 to 4 inches will reduce the flow rate (CFM) of the fan.
