Hi there, I am in need of some advice.
I have a tiny shop (~150sqft) in parts of my finished basement. It’s been a little over a year now that I had to give up my garage shop ;-( so now Dust in the air is very much an issue. Not only for my lungs but for everyone elses and the dust all over the basement.
So I have been thinking about building my own air filtration system based on commonly available filter sizes (14×20, 16×25). I got a blower at the market a few weeks back for $10. My guess is about 500-700 cfm, so more than plenty for my small room.
As I have been going through old post it looks like some configuration require very frequent filter change. I know this is a good thing cause it means they are cleaning a lot of stuff that would otherwise end up in your lungs but being a procrastinator for this type of things, I was thinking about putting infeed filters at both ends of the box, thus doubling the effective filter size and having to change them 1/2 has often!
But it occured to me, that I would also decrease the static pressure over the filter area, that is, loosing 1/2 the air flow per sq in, would it be enough to suck in the dust effectively. So with my little 500-700 cfm blower, should I stick with one 16×25 infeed or could I go to two 16×25 openings.
By the way, the outfeed will actually be blown outside during the summer and recirculated to the next room during the winter months. This will create a negative pressure in the room and keep the dust in the shop as much as possible.
