Topic tags/keywords: dust collection shop made how to

I have a Mitchell BenchVAC dust collector designed to mount 2 double arbor tools to the benchtop in order to collect dust.

Here’s a link to what I have: http://www.mitchellgolf.com/BenchVAC-Workbench-Model-Two.html

What I’d like to do is remove the 1200 ft/3 motor and design/make/build a dust collection system for my garage. Does anyone have any ideas on how to go about doing this. Any and all suggestions would be appreciated.

Thanks,
Chris

That system is only good for catching 10 micron and bigger dust particles.
You need to get down to 0.3 micron to get the really bad stuff.
Even the 2hp Harbor Freight collector many LJs use is good for 5 micron before modifying with cartridge filters.
I have no idea, from that picture, how the filters are arranged in that box and if they could be modified.

Also, in terns of removing the fan and motor for use as a stand alone collector, again, I have no idea how the fan is made or if it can be removed and used elsewhere.

Can you get pictures of the fan and or the inside of the box?

My first thought, when I saw that system was, “what a handy down draft sanding table I could make from that.”

Thanks for the reply, I’ll try to disassemble and post more detailed pictures…

You see the front has a piece that looks like a drawer facing? When you open it, there are 2 rectangular filters, one on top of the other. Obviously, suction is from the top and is blown out the bottom.

The reasons that I’m really wanting this to work out is 3 fold…I already own it, it was expensive, and it’s super quiet.

Okay…nevermind. Just found out that it’s an A. O. Smith 3/4 hp motor in a squirrel cage. I have been using it for downdraft sanding table. Looks like that’s all she’ll ever be.
