Project Information

In an effort to help control sanding dust in my shop, I decided to build a dedicated sanding table.
This one has an additional benefit of being an air filtration system, with an old
furnace filter I salvaged installed inside. You can leave it on while working elsewhere
in the shop, and it will filter the air for you…
(I haven't finished the wiring for it yet…hopefully this weekend)
It was built using ShopNotes issue No.24, and will use 3 standard 16"X20" furnace filters,
that are replaceable. There will be two filters on top, and one below the blower.
I enlarged the holes in the quarter inch pegboard for the top to 3/8",
for more suction capability through the top.
Looking forward to firing it up…

Update: I finished the wiring by adding a switched outlet to the side, and added a 50' extension for powering the unit. (This hangs off the back) I can plug it in anywhere in the shop just once, and power other tools from the outlet. The switch also allows me to run the fan whenever I want dust collection.

You will be glad you built yout table. I converted an old drafting table to a downdraft table a while back and I find that it makes a world of difference. That was one of those "I wish I had done this sooner" projects.

A sanding table that doubles as air filtration system, very nice indeed.

Nice work, wish I had more room in the shop to have one of these. Well done.

Just now sanding my first major project and wish I had one of these!

Out of curiosity, how did you come by the blower/motor?

I have a friend in the HVAC business, and he gets them quite often
when replacing furnaces. I actually have another one sitting on the shelf
that I hope to include in a hanging air cleaner as well.
I'm not going to use that one for awhile though…too many other
things taking priority right now.

Update:
Since I'm on vacation this week, I decided a couple improvements to the collector would help,
1. I added a switched outlet, to allow me to operate the fan whenever I wanted.
It also allowed me to plug in various tools, irrespective of the collector's AC input.
2. I scavenged a 50' extension cord, and permanently attached it to the fan.
This allows me to plug it in, from anywhere in the shop (or garage) at just about any distance.
