Reread Bill's cyclone research. I am in the market for my 1st dust collector. Onieda is local to me ~15 minutes away. I would just like to sort some stuff out. According to Bill, each machine needs about 1000cfm at the machine to get the fine dust. I think he means .5 micron. 1000cfm needs 500 sq/ft filter. Looking at clearvue cyclones, (Bill approved) the units have two wynn filters for a combined 600 sq/ft. Using his rule of thumb these filters should be mated to a 1200cfm max motor. I find it hard to believe that the 5hp Leeson motor only sucks 1200 cfm.
Seems like Bill implies everything on the market is rubbish except his cyclone.
Onieda's filter is a hepa and according to their website it is only 110 square feet. According to Bill that is enough to support 220 cfm at .5 micron.
I have a headache now. I was really considering going with 1.5 - 2 hp onieda/grizzly/jet/whatever. Bill just rained on my parade. super sadface.
Maybe I missed something in Bills literature, or am missing the concept all together, but there is nothing manufactured that will save my lungs except a clearvue cyclone?
With that being said I am going to go to the garage and sand my bed, while holding my breath.
