Project Information

This is the new air circulator I just build about 6 weeks ago. I was waiting to post to see how well it works and it is as good or even better than some that have been in shops I have worked in. It cost about $110 all together and all it is is a box out of ultra light mdf and a squirrel cage blower from a hvac. You mount it in the box and frame around the blower. The blower is going to suck air to the circulator and you put a filter at the one end to catch the dust! I will fill in more but running out to go camping! Any questions please ask and I will answer. Sorry first picture is not up right.

I have about the same amount of money into my shop made air cleaner. It really is a simple build. I still need to install it though.

I have three of these in my shop that I made. Two were from plywood I had in the shop and I bought plywood for the third one. At first I used the washable electrostatic filters (two on each box) but they allowed too much dust through them. I soon discovered the are not as efficient as the disposable paper pleated filters.

Way to go Brian,
I had to replace my AC/furnace this past Spring. I kept the furnace unit and squirrel cage fan, just for such a project. I need to get moving on my version ASAP.

Very Nice. My filter is a $16 box fan with a standard and then a HEPA filter duct taped to it. Not sure how effective it is. But it does collect dust.

Yah, I use the box fan with the two filters too … collects alot of very fine dust. I added a gutter at the botom so the lose dust falls into it, when there is a layer of dust in there it's time to clean/change the filters.

Box fan, bungee cord and furnace filter! Wife saw it on TV on a home remodeling show. It works! I vacuum the filter with a Shop Vac frequently.

For anyone with 8' ceilings think about putting it in the attic ;-)

I use something similar in my finish shop-nice big squirrel cage fan inside a box with double filters on it - a looser filter on the outside, heavier on the inside. I just picked up a smaller unit a couple weeks ago and want to build one for over my workbench in the home shop where I woodburn and use the dremel a lot. I love to burn but hate smelling like a campfire at the end of the day and I think this would pull the smoke up and away without cooling my pens.

Like it. Just built one myself from a free HVAC motor and squirrel cage and case. Used left over scraps of 3/4 ply. I put my on a shelf over by a wall. If I put mine up on the floor joist, the family room above would feel the vibration.

I used similar components, and built mine on locking casters,
with a long power cable… I can wheel it around to anywhere near the mess makers
in the shop…
They do work really good…

Good job ! Most of the commercial ones seem overpriced for all you get.

An air filter has been on my mind…that's for sharing this alternative. Would be interested to hear how it
performs…
