Since the first day my Oneida Pro 2000 was set up, I have had problems with dust bypassing the cone and clogging the filter. It has been so bad that on some days when sanding on my dual drum sander I have to blow out the filter two or three times to maintain the air flow for proper dust collection. I just don’t have the extra time on those days to baby sit the filter so I decided to look for other options. After numerous calls to Oneida, I heard the same old song and dance time after time, “You have a leak between the cone and collection barrel”. NOT A CHANCE! I worked on it and made it as closed as it will ever be.

First I looked at the Thein separators and made two, one for the sander and one for the jointer. Each was an improvement but I was still having to blow out the filter often. As I was out on the loading dock blowing out the filter with compressed air, I received dirty looks from my neighbors as the large cloud of dust went everywhere. Not only was the area a mess, so was I.

When the Thein separators didn’t do as I had heard, I looked for a professional industrial dust collection company. Here in the furniture capital of the world, there are companies who specialize in dust collection so I decided to try one out that came highly recommended.

The baghouse contains 10 – 8” polyester bags with anti-static carbon strips for static control. Once set permanently in place and attached to the ceiling for extra stability, I will replace the flex hose with metal duct which should increase the air flow and remove unneeded friction. Once we fired it up yesterday, the air flow through the blast gates was higher than usual even with a freshly cleaned filter and I expect it to be easier to clean and provide better air flow and suction.

If anyone is interested in the baghouse further, I will be happy to supply additional photos and the name of the company owner who installed it.

Send me some info and pics. I am working on setting up my new shop here in west texas and need to add a bag house as I can no longer blow it outside.

After three hard days using the new baghouse I can honestly say that it works much better than I expected and the increased air flow through the cyclone is very noticeable. In fact, with the old pleated filter, I would have it clogged up within one hour after starting sanding. Now after three days which has included several extended sanding sessions, the bags are breathing easily with almost nothing in the collection bag below. (Except for when I purposely allowed the collection barrel to overfill then the bag did collect some chips.) I believe I have found the answer I was looking for which will make my life easier in the shop and help keep the air and my clothes, cleaner.

I have no idea what the efficiency is or the micron rating, what I am interested in is how often I have to clean the filter or bags and how well the DC works. As an example, with the filter Oneida sent, I would see it clog within 30 to 45 minutes when sanding which required me to unmount it from the DC, take it outside and blow it out with an air hose. I wasted an easy 30 minutes each time and p!@#$ off the neighbors with the dust cloud blowing in the wind. And when I reinstalled the pleated paper filter which they claimed was a HEPA filter, I could see dust particles passing through the filter when I restarted the DC. So much for a $400 pleated paper HEPA filter. Today, after 45 minutes of sanding, I truned the DC off and shook the bags. Very little dust fell off the bags into the collection bag.

Now, the DC seems to pull more air, the efficiency of the cone seems to be increased with very little dust entering the bags and I see much less dust swirling around the room where the DC lives. There is less saw dust in the bottom of my two cabinet saws, the separator at the jointer works better and the separator at the sander seems to be working better as well.
