Dewalt air mover to filter conversion

I had an old dewalt air mover and needed to try and reduce paint fumes in my basement. I use an 8inx8in charcoal filter in the tray and a 3in abs pipe to guide the air out the exhaust. used existing screws to mount the intake cover plate and filter tray. exhaust plate is a tight fit. I needed to use a mallet to tap in on fully.
