Topic tags/keywords: question dust collector


I have been using the 441 d/c for several years now and love the machine, all except for the dust bag at the bottom of the filter. It is such a pain to change and replace. I was wondering if anyone has come up with a better alternative to using the collection bag?

I’d thought about somehow sealing a bucket to the bottom of the filter and then just popping the lid off… but the circumference of the filter is just over 5’ which makes it hard to find a suitable alternative. In fact, the filter is so wide that I’m unable to completely reach around the filter while putting the bag back on while simultaneously securing the band clamp that fastens it all together.

Any ideas would be appreciated!

If I were trying to solve this, I’d do something similar to what I have with my much smaller DC plus filter.

A plywood shelf with an opening cut into it that the filter sits on. You can line the bottom of the filter with a gasket material. Then below that, a barrel with gasket material on the top that is tight to the bottom of the plywood shelf using 3 wedges that the barrel sits on.

You can line the barrel with the bags. And the barrel doesn’t need to be 5 feet in circumference, just larger than the size of the hole of the filter. This is for fine dust, post the separator, so presumably not much material will be collecting there.

Make a removable pan.
Wynn Environmental sells a filter pan to give you pic of what i mean:

Dust collection pipe mfg sell a pipe cap for most pipe sizes. Which can also be modified to create a removable cap.

Make one with 5 gal bucket and some plywood. Use an oversized hat/ring on top of bucket with slots/hooks to allow short ball loop bungee cords to be used to hold the hat to hooks riveted to the outside of filter cover. Cut a slot in bucket, and RTV piece of plexiglass on inside of bucket to see when it needs to be emptied.

Know I have seen someone make one, just can’t find a pic online when i need it, sorry.

If you GOOGLE DIY cyclone filters, you will find a lot of solutions using various buckets and garbage cans. Ine they put a window in to see when it was full, but suggested just empty it when you take out the trash.

I intend to add the Oneida cyclone to my jet and use two small garbage cans. If the cyclone is working well enough, there should not be a lot dropping out of the filter. I expect to use a 5 gallon bucket, but I am a hobbyist shop, not production.

I purchased a screw lid adapter for a 5gal bucket and attached it to the bottom using a plywood ring so the bucket can be screwed on.

Thanks for the feedback!

After looking at your suggestions I found this video that covered a couple of ideas that you guys had suggested!

I had even considered cutting a 55gal drum down to height and duplicating the dust collection barrel that came with the d/c.

However, both the pan or bucket approach would be so much easier… I think I’ll start there!

Have your say...
