Hi All,
Here is my situation... I have a basement shop and only work there in the colder seasons (live in NY Metro area), maybe 4-5 months and only on weekends a few hours at a time. I’m a hobbyist at best, but plan to spend more time there when I retire. I have a Grizzly 2HP, bag based dust collection system. I've done some duct work with standard 4" black pipe from the box stores with 4" flex hose for routing things to my machines. 3 drops support a table saw, jointer/planer and a third gets swapped between a router table, band saw and miter saw. I know there are lots of debates about grounding. My DC runs not more than 5 minutes at a time, so I don’t see it as an issue for me, and thus far it has not been - no shocks and no hair standing on end unless my wife calls me for dinner. :-)
In short, I have a LOT of the very fine dust in my shop and I want to get rid of it by removing the bag and exhausting outside. I know there are several threads on this subject - I've real virtually all of them, including Bill Pentz’s site at length. That said I think I want a separator before my DC, then a cartridge filter, then send everything else outside. I have two windows in my basement, one of which I can convert to an exhaust port. One is next to the furnaces (see below) the other (preferred) is under a deck that has a 3’ crawl space.
So, first, I wonder what folks think of this approach. I know this is a spirited subject, so feel free to tell me why my plan is genius or assinine. :-)
To complicate things, my shop is in a part of my basement that includes two oil fueled, forced air furnaces and an oil fueled hot water heater. My concern is that venting the air outside will create enough suction that I could pull carbon monoxide into the shop from the exhaust of the furnaces/water heater. I run the system now with the bag and have not had any issues, but it is venting (lots of fine dust) from the same room it came from, so there is likely some kind of pressure balance there. If pictures help here say so and I’ll take some.
So, without starting a Hillary vs. Trump discussion (could not resist :-), what would you folks do here? My goal is to get the bad, really fine and invisible stuff out of the house.
As always, thanks for everyone’s feedback!
Regards,
Paul
