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.
