My shop is always dusty and I’m perpetually stuck on Allegra. Maybe this will help! Got a steal from my buddy Gus on the fan

Looks pretty cool. Do you intend to mount it or leave it as a tabletop ?

I think your workmanship is outstanding. But I wonder if that puppy couldn’t use about 3x’s the filter material. For instance if you are mounting it vertically, as shown, that fan would really grace a stack of Wynn cartridge filters, or a good quality housed filter bag. What is the size of the motor and what does that spec sheet on the table say of its CFM and SP?

Don’t know bout the cfm is but its got a half horse Marathon motor on it. And it’ll suck the filter right up inside, had to add extra braceing. I like your idea about adding more filters. I was going to stick it above my shop (see workshop pic’s) to get out of the way. I may change the design on it and try one of the Wynn filters. What I would really like is to find a good washable filter because its going to get a good workout.

Looks impressive but it’s best to handle dust before it gets in the air. Good luck with that,I hope it works great.

That is differently a different spin on a air filter system and I will be interested to see how it works after you have used it for a while. Is that a roof top style motor/vent system?

I have four dust filter units in my shop…one is a jet and the other three are ones I made with squirrel cage motors and filters. I have washable electrostatic filters in all of them….but the washable filters are not as effective as the pleated disposable ones. You definitely have to use more than one filter and can probably get away with using a washable one if you use a disposable one behind it to catch the dust it passes through.
I spoke to several companies that make or sell washable filters and they all agree that the washable filters are not as effective.
I am also looking into how i can use a wynn type filter with the squirrel cage units if possible.

Thanks for the info. I was trying to keep away from the Wynn type filter because of the expense but I guess you can aways blow them out.

That’s thinking outside the box. Nice build, hope it works good for you.

I read on LJ about a man that said he had used and cleaned the same filters for 5 years. I am not sure how often he works in his shop but that is a long time for a filter. He said it was as good today as it was when he got it. That is in use on a dust collector. This is a nice looking rig you have here.

Consider a speed control? An electronic type will help the life of your motor. mounted my dust filtering system from Grizzly in the rafters of my shop. Efficent use of space? i thought sountil I had to getup there when it stopped working. LOL! Grizzly was on top of it, just I’m kida woosie. So if you mount it up and out of the way, make sure it is easy to get to it. A downdraft table is my next dust control device.

Hey Ed,

I’ve wondered about these rooftop units and how well they might work in our shops, either as a general air filter, as you’ve done, or as a part of a collection system. So now you’ve got a couple of years use out of it, what’s the followup? How did it pan out and what mods have you made to it?
