Does this look like a good deal?

If it was here....... I would take it.

Anything that helps keeping the dust under control is worth having.
The price seems fair. I would start it up and listen to the motor.
 
That price looks really good for that dust collector.
I would highly suggest that you get one of these to go in between your dust collector and the hoses to your equipment. Expecially if you plan to use the shop for something other than small turning
Woodstock W1049 Large Dust Collection Separator - Dust Collection System - Amazon.com
I have a Delta system that looks almost identical to the one you posted and when I would use my planer or jointer the inlet to the fan would get all clogged up and then I would have to completely disassemble that part of the unit. This part fits on a garbage can and will separate out the large pieces from getting to the fan on the collector.

That may or may not good be a good deal, would need to know the jet model number and the micron rating of the bag. There are way more efficient systems out there. Check out the canister filters and the cyclone systems. Your lungs deserve the best you can afford.
 
That is not a good filter for the very fine bad stuff. Bags let the fine stuff through.


Set your specs for 1 micron filtration as the minimum. Fine stuff you cannot see is the bad stuff that stays in the lungs.
 
I've had that model (or maybe the predecessor) for about 10 years and have never had a problem. As mentioned by others, it would be best to get or modify for a filter instead of the bag. Since mine is in another room it doesn't seem to be a problem for me. Dennis
 
Well.. I don't want to make one. I guess I bet'ta up my budget significantly. This was all great insight. Thank you.
 
it seems like many come with a 30 micron filter; i guess the idea is to swap-out the bag and replace it with a 1 micron ?
 
Tony, the Jet is a good unit and the price is right, but it needs some modifications to be safe for inside use.

If you want to get crazy -- here is what I did with my Delta 50-850 dust collector. (It is a similar design to the HF unit that twinsen suggested). If you have the luxury of being able to exhaust outdoors, you can set up like this. For those cold Georgia winters or when you need to recirculate the air, you could run the exhaust duct into one of the rigid Wynn submicron filters. (there is a library article to mod a HF unit for one of these filters. None of the bags are really safe from what I have read. They catch the nuisance dust and pass the killer particles on to you (but the shop looks clean). It is my understanding that 1 micron is not really safe, but I defer to Jim on that.

So here is what you see in the picture:

  • In the middle, sandwiched between 2 pieces of 3/4" MDF, is the separator ring from the Delta. They are grooved to from a tight seal to the ring. The top one has a hole for the pipe that goes to the impeller. The bottom has a Thien baffle slot that runs 240 degrees around from the inlet.
  • Large particles drop into fiber drum below.
  • Virtually clear air is sucked up from the center of the Thien vortex into the impeller and exhausted outside (top pipe)
  • Motor is above the impeller
  • Inlet to the ring is the ductwork to the left in the center of the picture.
There is a cross-section drawing of the separator ring in my Gallery if you want to see it. Since I am an ex-aerospace guy, I used a 6" bell mouth entry to the impeller intake duct. You can further improve the airflow by using some flow straightening tubes inside the impeller intake duct :rolleyes:

This thing really moves the air and the Delta motor and impeller is pretty quiet. Separation is almost perfect as no dust builds up on the exhaust flap or surrounding area outside.
