DIY Dust collection with squirrel cage fan

I believe that would be too little power for a dust collector, but would be fine for a room air cleaner. I used one like that for a couple years in my homemade air cleaner. I just made a box and put in a stack of furnace filters, stuck the fan in the exhaust end. I'm using a small box fan now because it runs quieter. Blow out the filters once in a while and they last forever. A lot of dust will get through a cheapie furnace filter, but not much gets through a stack of them. My current iteration has a stack of 10 cheap filters plus a fine final filter, but that seems to be overkill. Most of the dust gets trapped in the first few. I'd recommend 4 to 6 plus a fine one.

Say what you will about Grizzly's stationary power tools, their dust collector bags are the best in the business. 0.3 microns (3/10 of one micron) is exceptional. I bought a larger size one than what came on my dust collector to maximize airflow (more square inches equals less resistance). Had to stitch up the opening to adapt it, but that's no big deal. It works great and I can't recommend it highly enough.

Like Mike said, your 1/4 horse motor is probably way too small. I realize you desire to save the green stuff. I am getting ready to try something that may increase the CFM of my Harbor Freight DC. I am going to add a second bag to it. Will place two collector rings on top of a short plenum, centered over the present collector ring. I am using a "Shaker Felt" bag from Highland Hardware that is susposed to stop everything from .1 micron up, once it builds up a dust cake. Seems to work well with the single bag I have now. However, with a rate of 40-45 CFM per square foot of filter area, the presnet bag limits me to about 600 CFM. Hopefullly, repeat hopefully, the dual bag setup will get me somewhere near 1,200.

Kev> Hello all,

I agree. With the air cleaner I built, I use 4 plus a fine and it seems to work fairly well, The first three coarse catch the bulk of the retained material

You might as well not have a dust collector. That canvas won't stop any of the harmful dust from permeating your work area. If you want better protection *AND* improved airflow, get a pair of 5 or 1 micron Shaker felt bags. I got a pair for my 650 CFM DC and it made a HUGE difference in airflow. Felt like I got a new DC.
