JDS Air-Tech 2000 Model 750
I had planned on making my own air filter before I bought
this. I even picked up a squirrel cage blower from eBay for $40. My plan
was to build a plywood box and use a series of high quality furnace air filters
to pull the dust out of the air. However, the blower wasn't powerful
enough. Three good filters would have been about $45 more and the plywood
wood would cost another $40. Add $10 worth of paint, hinges for air
filter access, rubber seals, etc. and I'm up to around $160 (not including the
replacement squirrel cage blower because the first one wasn't powerful
enough). Also, because I was using some vacation time due to the birth of
my son I was in the shop all day and I
wanted to have an air filter because the MDF dust was bothering me as I made my
router table.
Because of all these things I decided to cut my losses at $40
and buy an air filter from Woodcraft. That way I'd have a filter in just
a few hours. I went off to Woodcraft and picked it up. You can
check out my review here.

That's the intake side. |

This shows the display settings (timer, air flow, etc.) and
the output side. |

Here you can see the placement of the air filter in my shop.
I put it rather quickly but I've seen given a lot of thought to its
placement. The general rule is that you want the clean air blowing
toward you. However, my experience tells me that for dust collection
it's better to have the dust sucked right into the filter. Now the
filter isn't really designed to collect dust from the source but it does a
good job of it. You can see it drift up and into the filter. In the
end, I decided that I got lucky with the placement. I tend to spend
most of my shop time at the bench. (That picture has bench 1.0 in it,
I've replaced it with version 2.2.)
I spend that time using hand saws, chisels, planes, or simply thinking and
planning. All my major machines have dust collection routed to the so
the air filter doesn't factor in with them. The only thing that isn't
collected is saw from the occasional circular saw usage or when I sand away
from my downdraft table. In
those rare and short duration cases, the operation happens right below the
intake side on a pair of saw horses.
In summary, I spend most of my time with clean air blowing on my but I do
short saw dusty operations below intake side. |
