Curious what you guys would pay for some dust collection stuff, or better yet, what you think it’s worth! :-) Harbor Freight DC (about six months old) Plastic SDD mounted to a 30 gallon brute trash can with 6” hose. A Rubbermaid bin filled with 2.5” DC stuff as well as 4” DC stuff. In addition collector remote control with three fobs and about 30’ in 4” pipe and all the fittings that go to 5 tools.

Thanks a bunch in advance!!

$237

I have a hard time coming up with more than $300. I figure about 50% of new price considering it’s used, and you have to buy all of it and not just what you need. The guy’s probably got $1000 invested in the system cause it all adds up, but a lot of that is in the piping and distribution system, which won’t exactly suit your layout and you’ll have to buy additional stuff. He’s probably hoping to get $500-$600 back out. My other comment is that the impeller on the HF collector is pretty small compared to most 2HP collectors and it pulls quite a bit less. You put the static pressure loss of a SDD in front of it and it drops off a lot more.

Check out this article which compares the fan curves of several 1.5 and 2 HP collectors including the HF 2HP one.

You get this, it doesn’t suck has hard as you’d like, so you decide to get a cartridge filter to improve the airflow, so now you’re in for another $150, and in the end you’ve still not got something that does what you want. Get something with a 12-13 inch impeller that moves >1000 cfm with a separator and duct. They all spin the impeller at the same speed, 3450 RPM, it’s all about the impeller size and design.

All that said, lots of guys have the 2HP Harbor Freight collector and mostly they will say it’s a great deal. I think one has to admit that it’s the most collector that very little money can buy. It’d be better with a bigger impeller. The thing is, they could put a bigger impeller on it for very little difference in cost if they knew you’d be putting the static pressure loss of a cyclone and ducting in front of it, but they size the impeller so it won’t burn out the motor if people run it wide open with nothing on the input. The more air it can get the more load it puts on the motor.

I’d be hard pressed to pay more than $200 or so for all of it. Mostly because of the things Bob pointed out above.

The HF DC works fine for connecting to individual machines with one short ~10ft flex hose, but if you are planning to build a duct system for several machines you need a stronger blower.

All this stuff is mine I’m selling to a friend as I’m clearing some of it (may not have been clear) I had a jet canister DC that I gave back to the old man who always regretted selling it to me. He gave me his new HF DC and 100$.

I may tell my other friend 300 for all of it and go from there!

Thanks again for the help!

Kinda’ like the scrap dealer when asked “What is the price of copper today?” He responds; “You buying or selling?”
