Can anyone tell me they have used an air filtration unit in their cellar
workshop? I am wondering if it is worth the money. I have spent both time
and money to get my dust collection system to a point where I have very
little dust on things. Wouldn't the dust just fall to the floor?
The stuff that the air scrubber gets is *not* the stuff that falls to the
floor. It is the one micron stuff that hangs in the air, gets in your lungs
and is the *most* harmful dust in the shop.
Get the air scrubber.
I built mine using a twin squirrel cage blower. It has the three
pocket filter (from Penn State), above that is a fine furnace filter
then a coarse furnace filter on top to catch chips. The top has holes
and can be used as a sanding table or it tilts up for greater air flow.
It sits near my lathe, where I do most of my sanding. I also have a
dust collection system which I use when sanding. This air filter still
collects a bunch of the fine dust.
I'm pretty confident that if you run an air filter in your dust
collectin' cellar shop, the filter will quickly develop a coating of
dirt. It's the fine particles in the air that you should worry about.
I'm not sure how large your cellar is, but you can probably get an
adequate filter for ~325.00. Personally, I recommend it.
As another responder noted, this kind of air filter gets the really fine
stuff that hangs in the air, and unless its really thick, you probably
don't see it.
I have one in my basement woodshop - from JDS Company. It has an
infrared remote, several fan speeds (I always use the highest) and a
timer. I usually turn it on and set the timer for 4 hours when I start
any work in my shop, and I keep it running as long as I'm there. As I
leave the shop, I hit the button again so it runs for 4 hours after I'm
finished. I can tell you it catches quite a bit of dust, in spite of the
fact that I have and use a central dust collection system connected to
all my stationary tools, too.
Placement of the filter matters. The idea is to get a circulating flow
around the shop and through the filter. When you purchase one, it should
come with instructions that describe those issues, and will help you
decide where to put it.
