This collector is ok if you have short ducting and don't need much air flow. The air flow I measured was much less than claimed. Packing was inadequate, I had to get a second unit and got enough parts from 2 units to make one with some extra help. It probably has enough air flow for 1 belt sander or joiner or small planer. If you do get this type of collector get the pleated filter and clean it daily. These bags plug up in a short time and there is no way to get them clean. No matter what collector you use, it will never get all of the dust. I recommend an air cleaner in addition. Your lungs are worth it.
