4 Inch Duct To Carbon Filter

This is a shroud for a large carbon filter, 7 inches in diameter. It covers 100 degrees out of 360. I have a fan pulling air out of the filter because it has a fabric filter on the outside. I wanted to retain the use of the fabric and keep it on a pull configuration. This will allow some if the filter to be use for something i want filtered through it while still be able to filter around itself as well. This works for me, feel free to modify it for your needs.

*Will upload picture when its complete
