Ok as on two other threads I started with talking about Xmass gifts and fell into two areas Dust Control and saw safty.
This one is about improving Dust Control (not dust collection as such)
This is for a shop that has a DC system using a Delta 1 1/5 HP unit.
I figure the options for this are pretty much as follows.
- Add a Room Filter (if so what version)
- Replace the top bag (a .5 micron) with a cartridge. Cleaning the back is a pain, and cartridges are supposed to be better, but who makes one to fit this?
- Replace the whole Delta DC (seams extreem it is not yet 2 years and seams powerfull enough to get the job done)
- Add some sort of guard for the Table say that has DC from above (this is part of the saftey list but fits in here also)
Any other ideas?
Any and all of these that could be done for under $400 ish would fit in.
So what do you all think?

Doug,
You clean the bag? Didn't know I was supposed to do this. I just figure most of the crap falls into the bottom bag when switched off and the amount left on the bag helps filtration. Please correct.
I don't have to remove the lower bag as often since I hooked up my LV trash can top on a big trash can inline with the ingress. Lower bag fills very slowly now. Still enough suction.
I also have a delta overhead air cleaner that would use up most of your budget. That's to collect anything small that escapes collection at the tool and filtration in the upper bag. I use a 2.5" shop vacuum and a central vac (sometimes at the same time) for collection on smaller tools.
When I decide the perfect location and stop moving my TS, I'll do a ceiling mounted collection.

Well I dont so much clean the top back as all the C@#$ falls out of it when I take the lower back off, makes a big mess and gets me annoyed.
Doug
k, I know what that's like. :) Now, I shake the bag before removing the lower one. Even that won't happen for a while now thanks to my trusty LV trash can solution. Andy
Alas I dont really have room to put one of them trashcan cyclone things. Wish I did but space is what it is.

Yes, you definitely need to clean the filter bag. All of the air coming into your system has to go somewhere or the system won't work. That "somewhere" is through the filter bag and back into your shop.
Really fine dust (e.g. sanding dust) will "cake" onto the filter bag and eventually reduce the air flow through the bag which reduces the air flow through the system. Cleaning the bag is a really messy job, but you'll get a substantial increase in the system flow after it's done.
I just upgraded my Jet 1100A DC with a "Dust Dog" pleated filter unit. It has flexible paddles inside that are turned by a handle and will scrape the fine dust off of the filter so it can fall into the collection bag. It's only been on for a few days, so I don't know how well it will work, but everyone I talked to said that they worked very well.
Yeah that is about what I am looking for to put on the Delta, but I do not see anyone making them. One one I had a link to that fit did not seam to have the handle the one that had the handle did not fit. Go figure.

Dave, Thanks. Does that mean I need to launder it or just shake it out when I empty the lower bag? I assumed that I would open the pores of the filter and reduce its effectiveness for small particles if I laundered it. ? Andy
All I ever did was shake mine out - while making sure that there was a good breeze and I was upwind. You ain't gonna believe the amount of dust that's going to come out! - lol
I have a port at the workbench where I can connect hoses to my sanders as well as connect the shop vac hoses to vacuum up the sawdust and stuff. When everything is nice and clean, it makes a sort of whistling/moaning noise when the blast gate is open. That was always my "cue" for cleaning the filter bag. When the noise stopped, the bag got cleaned (shaken, not washed). When I put everything back together, there was a very noticeable increase in the flow through that gate.
Now that I have a bigger DC (1100 cfm v.s. 650 cfm) and the pleated filter, the gate makes a high pitched whistling sound and there's enough flow to make me worry about small parts and stray animals.
Actually, I once (repeat, once) ran the filter bag thru the washing machine. SWMBO made it VERY clear that washing the bag was NOT a viable option for the future. - lol
Noted: no DC bag in the washer. ;) Do you have small pets? I saw a mouse run across the shop floor a few weeks ago while cleaning up with the shop vac and instictively, well... I'll stop there. Andy
No small pets here. No "critters" either except for the odd squirrel that runs along the fence and scurries up a tree.
Several feral cats, however. A couple of them have tried to come into the shop (garage), but changed their mind when I ran them off.
Those cats are the basis for a neighborhood near-feud. Our neighborhood "cat lady" has several cats and won't get them spayed. Since she feeds them outside, she attracts every stray cat around so there are 10-15 cats wandering around all the time. When someone complains, she swears that they aren't all her cats (technically true, I suppose) so she isn't responsible for them. Then, she goes bananas if someone calls animal control.
So you're saying you need a 6" duct and a large hood close to the floor? ;)

I had a bad mouse infestation in my house last year and I did just that. Whenever I saw a mouse I would use the shop-vac to suck 'em up. Works great, even with the smaller 1 14" hose. A minute or so in the cannister with the thing running seemed to be enough to finish them off. probably not most people's prefered method of pest control though.

I remember seeing a believe it or not documentary about some entrepreneur who used a giant vacuum hose to suck prairie dogs out of their burrows and into a tanker -- alive. I believe he exported them to some place where they were considered a cute pet, or a tasty snack. Now if only they'd come up with something big enough for raccoons. A wise man described them as an insufficiently endangered species. I'd sooner have a mouse on my floor than a raccoon in my rafters. Or a bat in my belfry. Jim
MMMMMMMMMMMMMM prairie dog on a stick! deep fried and battered of course.
a mouse on my floor i could deal with, but i had LOTS. my traps would catch 2-3 per night and this went on for weeks, and thats not counting what the poison got. i finally had to overcome my cheapness and call the exterminator.
Hi Doug,
