erikbojerik Posted February 13, 2009 Report Share Posted February 13, 2009 Check it out - I finally got inspired to build a downdraft sanding table. It has a 30" x 48" table surface (1/4" pegboard on 2x6 frame) on a cabinet that has inside dimensions of 25" x 48" (so it holds 3 of the 16"x25" air filters). Took me the entire weekend and ~$350 (half of that is for the fan), but it is really doing a great job keeping the dust down. The switch turns it on/off and the outlet is handy for the sandy. 5" casters (2 locking) so I can move it anywhere. The front edge of the table extends about 5" out from the cabinet, so that I can clamp to it. The table is hinged to the cabinet so you can lift it and access the filters (here I have some cheap fiberglass pre-filters on top of the better white folded filters). The entire inside is caulked so that I don't lose any airflow - I want the fan to pull air only through the table. The fan is a 3000 cfm wall exhaust fan, and it is amazingly quiet. Even when I'm not sanding, I'll turn it on just to circulate and filter the air in the shop; it will circulate all the air in the room every 2-3 minutes.

Woodenspoke Posted February 13, 2009 Report Share Posted February 13, 2009 Great job. Wish I had extra shop space for someting like that. What grade of filters are you using? Quote Link to comment Share on other sites More sharing options...
erikbojerik Posted February 13, 2009 Author Report Share Posted February 13, 2009 Great job. Wish I had extra shop space for someting like that. Yeah, I had to eliminate a floor-standing shelf with all sorts of tools on it, but was able to space some wall-hanging shelves closer together to make room for another layer - that's where the tools went. What grade of filters are you using? The white folded ones are the entry-level 1" thick ones @ $3 each - we'll see how they work out.

Hopefully better than my home heater filter works, LOL Maybe some cheap micron pre filter material on top or Multi bag filters behind it? I know more money. Heres a link to one filter source for reference. Filter reference Anyway give us a follow up in how it works with the $3 filters. Quote Link to comment Share on other sites More sharing options...
