I recently add a Dust collection system but as other have found it only get part
of the dust. I'm looking at the Jet 1000b unit and the JDS 750 unit. I would
like something quiet but able to filter my 20x20 shop. Any suggestions or
comments would be appreciated. Thanks again
If you want to get _all_ of the dust, you're going to need to consider a
mask or positive pressure face shield. Handheld tools, lathe, sanding
blocks, etc. are not going to be hooked up effectively to the DC.
It's not a cleanroom type of hobby.
Friends of mine who have an overhead filter rarely turn them on. They seem
to make that little difference.
who opens the garage/shop door for fresh air.
Open the door? You must live in the tropics!
My experience with air cleaners is the opposite, I have a home built one and
it gets turned on as soon as I walk into the shop. Before I was always
blowing crap out of my nose, now my honker stays nice and clean.
Weather gloat! I worked on the driveway, and in the shop, from 8:30 am
until 4 pm, with a couple of Scouters. An Eagle Scout project, benches,
built from Western Red Cedar milled from a tree donated by a family friend.

Well I have a fairly noisy one speed Delta sitting up close to the
ceiling in my 24x24 shop plus a home built filter sitting under my
workbench on the floor on the oppisite side of the shop...
I have to agree that they do not seem to do much...BUT those filters
are always loaded and need to be serviced quite a lot... SO they are
This thread comes up almost weekly. I know some people can get 100% dust
collection off of contractors saws and miter saws, but those of us who can't
devote 20sf to hoods are not so lucky. (The vocational ed school I took a
woodworking course at doesn't use DC on their saws because they feel it is
just a waste of energy; and they have a monsterous DC. They just have the
planners and jointers hooked up. I would like to see them do something
better about sanders and routers.)
My Jet works pretty good. After a days use I take the filter outside and
knock about a quarter cup of dust out of it. A good chunk of that would be
in my lungs otherwise. Can't say what the fine filter catches, for obvious
it does not take huge collectors it takes planning and usually a couple
connections. my tablesaw has under the table collection and I refitted the
overhead guard to a 4" hose. only once in awhile does dust escape when I cut
only on one side of the blade. it takes some effort and a big enough DC but it
is possible. it's better to keep the sawdust out of the air then catch it

I'll double check the DC connectors for leaks. I have a Jet DC-1100RCK with 4"
pipe to the Delta unisaw. I was using the table saw most of the day building a
DVD stand.. I don't care that much about the dust in the shop but had allot of
dust in the throat which was the concern.
Thanks for the suggestions
I've seen a lot of references to 4" pipe being too narrow, and
essentially choking off the DC. Sufficient airflow is one of several
points necessary to pull the fine dust into the DC instead of letting
it escape into the air.
A few guys that I have talked to like the Delta 50-875 in conjunction
with a regular DC unit. The Delta AF has a easiy to clean/replace
front filter and 3 speeds with a remote so you can set it and forget
it. That's the one I have my eye on.
I purchased the JDS unit. Amazon has a $25 off any order over $199 &
"free" shipping plus JDS is packaging an electrostatic filter and remote
with the unit. My total cost was $265.
A few weeks ago, I moved my turnery from the garage to a small room in
the basement. As our laundry and clothes ironing area is also in the
basement along with some of my wife's work clothes, sanding dust from
lathe work would really be a sore spot.
While I use a DC hose positioned close to the work that catches most of
the sanding dust, some still gets away - I can see it floating in the
air around the lights. The JDS air filter really seems to be catching
this stuff. I took the electro filter to the garage and blew it out with
an air hose and quite a bit of dust came out.
After reading the reviews of the Jet, Delta and JDS units on Amazon as
well as some very positive comments on rec.crafts.woodturning (google
"Lyn Mangiameli" and JDS - he talks about the upgrades JDS offers to
older units) I decided on the JDS. It's quality seems very good and it's
still USA made -- hooorah!

Used furnace blowers can be picked up cheap. Most will turn over
all the air in an entire house 2 or 3 times an hour so a 20x20
should be no problem. If you have a truck maintenance place or
truck rental/lease outfit in town you can probably get pleated air
cleaner filters used for nothing. Blow hem out and you're good to
go for catching the really fine dust.
And why not kill three birds with one stone - air cleaner/down
