I'm in the beginning stages of planning/building & setting up a dust collector in my garage.
My plan is to build a Thien Baffle style at first & then probably upgrade later on to a cyclone.

Being I'm planning ahead for a regular cyclone later on, I'll be mounting the blower section as high as possible in my garage to give me the most room I can get underneath the blower.

I watched this old video https://www.youtube.com/watch?v=k6kBkrE_4us and it shows a different way of converting a dust collector into a Thien style system.

I will have a cartage style filter after the blower, But the video above gives me the idea of possibly making some type of pre-filter box in the extra space I have planned for a cyclone later on.

Just curious if anyone has added some type of pre-filter after the separator, But before the blower?
