Hey hey HEy I spent today designing and laser cutting a box to fit the fan and filters and adapt to my 75mm pipe.
this thing is gonna work super well! Just put together the box and spun up the fan and there’s so much suction.
Now I just have to buy some air filters. It’s designed to take Toyota car cabin air filters, which are super cheap (literally like $10), rectangular, available with activated carbon media, and fit the fan size great.
The filter will just slot right in the top here (will be the side in operation)
Closeup of the back side showing large centrifugal fan mounted with free exhaust out the sides, and intake facing into the box. Also a small fan controller PCB with a knob plugged into the fan.
