Topic tags/keywords: dust collection filters

I have an old, old, old Jet DC 650 with an upgraded filter bag running thru a Thein separator. I have a small shop and generally only run 1 tool at once so this setup works ok. But i’m considering a further upgrade to a Wynn canister filter to replace the filter bag. My question is, should I spent the $$$ to put a filter on a dust collector that is this old, or just replace the entire unit (and get one with a cartridge already)? Do dust collectors ‘wear out’? Do impellers become less efficient over time? I’ve had no issues with my Jet but I could always use more airflow and less fine dust; it somehow seems unwise to spent quite a few dollars to upgrade an old machine and still have an old machine. I’d appreciate any thoughts.
Thanks
Jeff

DCs are nothing but a motor spinning an impeller. So age doesn’t impact them as much as total usage, and in most hobbyist shops that’s not a problem. Of course, some thing deteriorate over time, like cloth bags, maybe some seals and such stuff.But you say it’s works OK and you would like to see less fine dust. Those 2 comments seem at odds to me, and at least by my standards that is a pretty inadequate DC. Even so, a canister filter may help trap a little more dust….it might even allow a (very) small increase in air flow. So if the unit is truly doing what you want, adding the filter will not hurt anything, and may help a little. Oh, impellers do not become “less effeciant” over time, but they ma get a dust buildup on the vanes that needs to be cleaned off.

You are very limited running a 1 hp Dust collector. The Thien baffle reduces the effectiveness of it. The canister filter in my opinion would help clean the air.

Not dust collectors do not wear out.
But
Motors do need new bearings every 10-15 years.
If start/stop the motor many times a day, the start capacitors can wear out and need replaced.
Switches also wear out after many thousand cycles.
Parts to fix any one is < $25.

Which is whole lot cheaper than a new dust collector, even if new toys make us happier? ;-)

Can also add a cartridge filter for ~$100 as DIY project too.

YMMV

Best Luck on decision.

Only a 1 hp? I would start over with a larger machine, 2 or 3 hp. More airflow, better filtration. And an Oneida cyclone if you have the space. An upgraded DC is not a new toy, it is essential to your health.

Thanks, all, for the replies.

I’m both happy and sad that you’ve pushed in the direction I was already leaning. Guess I’ll start saving….

Cap’n – why did you choose a Donaldson instead of a Wynn???

I have the jet, which is a two micron filter, where the Wynn is a one micron. I added a wen air cleaner, and the air is very clean. I have a particulate meter hanging in the shop, and it shows very little one micron dust. No system will get it all, just going for the best I can. And there are many times to use an n95 mask, if you can find them.

- Jeffnorm

1) Positive reviews and information posted in LumberJock forums on the Donaldson conversion

2) Lower cost.
Bought the Donaldson from Amazon for ~$100 with free shipping when a 3rd party supplier put it on sale. The Wynn filter was double to my door. High shipping cost of large filter was a factor in selection process too.

Cheers!

The Jet DC 650 is a dog of a tool. I like Jet tools, and have many of them. I got rid of my DC650 and never looked back. I truly believe any other DC would be better. The combination of impeller size, RPM, and overall design doesn’t give good real world performance.

I switched to a 2 hp cyclone and it is night and day better. Look for something with a larger impeller.
