I have googled my brains out and can’t find any info on the machine. It’s a Northwood C-145T 3 HP dust collector with two bags and a height of about 10’. It seems that I remember the name from ads in old woodworking mags but my search only turns up industrial CNC machines. Can anyone tell me anything about this brand in general and this DC specifically? I can buy one for $200.00 from a business that is closing down. It’s been equipped with new high filtration bags and with 3 HP I can’t go wrong, or can I? what do you think?

The Northwood name was used on some imports, much like most other brands. They did under, though I can’t remember when. I looked at a Northwood 15” planer for a friend a few years back and did a little digging around about it at that time. As for the DC:, we’re talking about nothing more than a motor than spins a fan (impeller), so assuming thing isn’t beat to hell and the motor runs I would think a 3HP for $200 would be worth looking at. You will almost certainly have to get new bags (or a filter); even if the OEM bags are intact, they are almost certainly 30 micron which is unsuitable (IMHO) for DC use. I would think you could get that for less, but that’s just me.

I’d also check to see if it’s single phase or triple phase so you can make sure it’ll work in your shop. Echoing what Fred said, if it’s not all beat to hell and back, it’s probably not a bad deal.

For what it’s worth I recently bought a 3HP Shop Fox motor just so I could scavenge the motor off of it. Got a decent deal off of it but still paid a lot more than $200. In your case, add a cyclone separator (you could make it yourself or do what I did and buy one off of eBay, $250), and get a Wynn nano cartridge (about $160), and you’ve got the makings of a cyclone for about $600. Not bad…

Fred, They have already replaced the original bags. I can’t be sure from the photo but they look like the polyester felt high efficiency bags you are suggesting. They have the glossy look of felt with the PTFE treatment so I’m assuming they are. Yea at 200.00 for a three horse collector I don’t think I’ll pass it up. I’ll post comments on the efficiency after I get it so you’ll know whether Northwood collectors are a blessing or a curse.

gtbuzz, There will definitely be some form of separator in my future. I had a Penn State 1 HP portable that I mounted on top of a wall hung cyclone I built using plans from an old issue of Wood magazine and it worked surprisingly well. I’m leaning towards a Thein type separator this time. They are so easy to build it’s worth a shot and if I don’t like it I’ll just search for that old issue of Wood and build another cyclone. Tghanks for the reply.

I would say that is a probably a good deal. I bought a used 3HP 4-bag DC marketed by Belsaw for way more than that and threw away all the bags, put a Thien Baffle and 30 gal. trash can, and a pair of Wynn nano filters on it and it is humming in my shop today. The one you are looking at is probably one of the generic 12-12 3/4” dia. impeller blowers like mine. This should make a really nice dust collector for a typical shop with 6” ducting.
