It is about a 12”x16”x20”. The on/off switch is a 1 hour timer. Not only can I set the timer and then close up the shop but when the timer clicks off it is a good reminder of how long I have been in my shop. Seems like I burn through a couple of hours in no time.

Unintentionally I mounted it right by the light and it keeps down the bugs at night by blowing them right out the shop doors. The motor on this is pretty powerful. I used 2 filters on fine one course (blue/washable). The filters are in need of cleaning. I usually just blow them out with my compressor.

What type of blower did you use?

Would a fan work for something like this or is it not powerful enough? Like bowyer I’d love to know what sort of blower you used? Any fear of it getting too hot inside that box?

Thanks, and great idea/execution.

Great idea with the timer. I think I’ll add that to the one I built a while back. I like the 2 filter idea, too.

For the guys asking what type fan, an old furnace motor & squirrel cage fan combination works well for these units, and they are often free for the asking from heating & cooling contractors who pull them out to install new units. -SST

I thought I had a free one to use for this project. It came from my own air exchanger. How disappointed I was when I got ready to start the project. It is 220vac. I don’t have 220 in the shop.

Neat project and a good idea. We should probably all do this sort of thing in our shops rather than breathe that dusty air.

I used one of those squirrel cage fans.

Totally agree with Shopsmithtom about where to get one of these or if you search craigslist long enough you will find someone tossing one. You could also try searching craigs for a heating & cooling contractor and them shoot then an email asking if they have any. I’m kind of a craigs addict.

I did see an interesting article online as I was researching this project. It was about how fast air is recycled in a room based on the dimensions of the squirrel cage. They come in many sizes and the bigger fan the faster it recycles the air. I want to say that with my size shop and my size fan the air is supposed to recycle 5-7 times an hour. I can’t quite remember but it was something like that.

McLeanVA- I have never thought about the heat issue and I have never noticed it getting hot. I guess since it turns off every hour it probably wouldn’t have the time to cause a problem

Thanks for the post TMiller. Maybe it will inspire me to build one too, I love sawdust, but not in my lungs. Dusty, you can just send me your air exchanger as I don’t have one, but I do have the 220v.

agree with the heat and air shop for the fans. I went to my local heat and air place aftre seeing another shop made filter here. asked if they had any. He asked how many I wanted and how big…told him two…(Made one for the ceiling…planning on a down draft table or another filter on wheels to move around) he walked in his shop…and in two min. brought me two that looked almost new…no charge.

Said they throw dozens of them a month away and wished more people wanted them.

Wouldn’t it be better to turn it around so it sucks the bugs into the filter & blows filtered air in your face? (assuming it gets as hot there as it does here…it’s 102 already & barely halfway through the afternoon)

Greetings & Salutations,

I made mine with a blower squirrel cage and used some plans that I found in Shop Notes.

It has a sliding door on the bottome to change the filters which have 2 on the intake side of the blower and one on the exhaust side.

When its time to change filters I throw the first one on the intake side away and move the other 2 forward and put the new one on the exhaust side.

I have it posted on in my projects if you care to look.
