I posted this experiment which I did with my dust separator recently and thought maybe I can hook up a dust filter to my dust collector since I only use the 5” hose most of the time .
A simple wall mounted box made from scraps to fit the filter which I got from my daughter and it’s used but plenty good to use in the shop . Hooked it up to a 4” hose direct from the dust separator and sucks a lot of CFM and made a quick connect strap to hold it in place so if I want to use it on my drill press or mobile sanding station it’s quickly done .
The filter box is mounted high on the wall and behind my table saw where most of the dust is generated and it seems to do a good job and turns on with the dust collector switch which is located on my table saw .
This is in addition to the air filter I have mounted near the ceiling which actually does not work all that well and this being hooked to the dust collector has a lot of suction and will help clean the air more quickly .

Great idea and nice free filter. That said it’s on of the more expensive filters? do you have a free supply Klaus? Like the use of the existing vacuum rather than a seperate fan, but my dust collector is not sucking well at present and it’s to hot and too humid. 85% in the shop right now. I will keep this variant in mind. Thanks!

I like the idea Klaus. Two birds with one stone. Something to consider since its an easy build.
Do you keep your ceiling air filter going the whole time you are in the shop? Mine works great, I’m always cleaning or changing that filter.

Thanks guy’s
A simple idea and since the dust collector is running anyway and the material and filter are free why not try it and get rid of more of the fine dust ,the other filter just takes too long and a lot of it settles on the floor or shelf’s or my wife’s car and that is trouble .

Clever. I keep that in mind. I have a free 4” port on my dust collector (a King Indus. too) and it would be just right for this purpose. Good project for next Fall. Thank you for sharing such good idea (as usual).

Great use of existing equipment…
Except your are running a large motor (I’m assuming 2 to 3 hp) when you could be using a 1/4 to 1/2 hp motor to run a squirrel cage blower type motor (a used home furnace type is what I use) with a big savings on electricity and it can run continuously while your are working not just when the dust collector is on.

On mine the blower is inside the box and vents out the side. During the winter it blows over my wood stove and circulates the heat in the shop too. The blower came from an air handlers in the home heating system that circulated air in a 2000 sq. foot house so it moves a lot of air and really helps keep the shop, and my lungs, clean.

The whole point is that when the dust collector is running I can use it to remove dust from the air and it takes no extra electricity and I also get these filters for free and have quicker filtering when the dust is created . I have another air filter with a small motor that runs all day and shuts off later at night .

Thanks Serge
Give it a try and I think it will work for you also and you may even have an idea to improve it .
