Amazon.com Review:
This is the perfect dust collection system for the home woodworker. It packs a powerful 1-horsepower motor and moves a maximum of 650 cubic feet of air every minute. Top and bottom collection bags mean you score a hefty 2.6 cubic feet of chip/dust capacity. When we ran this system, we were impressed by how quiet it is--a great advantage for the home woodworker. The 4-inch hose fits standard dust and chip chutes on tools like your jointer, table saw, and planer--the big names in sawdust manufacturing! The AP400 is a great choice for the average home woodworking shop because it's mounted on such a small footprint--just 14 inches wide and 27 inches long--and it sits on four easy-glide wheels to move the system from one tool to another or into the corner for storage. Great power, great price. --Kris Jensen-Van Heste

Rating : - Good "cheap" dust collector
This being my 1st dust collector, I did extensive research and read a ton of reviews. It is good for 1 machine at a time only, and I would not recommend using a longer hose than is supplied with it. There is just not enough air movement for a greater distance.
The top bag (30 microns) is a joke. With normal shop lighting you can actually see the dust being blown out into the air you're supposed to be breathing!! This bag definitely should be replaced with a cannister from Wynn Environmental (#35A274BLOL) for an additional $95.00 cost. It's worth the money for better health and a cleaner shop.
I have been using the Delta ambient air filter above the AP400 to try to contain the dust released, and it does help but, it is not the complete answer. You HAVE to reduce the dust coming from the AP400 much better than Delta sees fit.
Also, some reviews stated that the AP400 is quiet enough to allow "normal" conversations while standing by them. NO WAY!! This unit is loud, just not the same type of screaming noise a shop vac makes. I can not hear my table saw with the AP400 directly behind it. Maybe something is wrong but, I have yet to discover what. It also seems to creeate heat in my shop. I have A/C but, when running the dust collector for any length of time, the shop certainly gets warmer. (It's only 9'X 18')
With better dust control I would have given it 5 stars but adding the cost of a good filter is apparently not the path Delta wants to take.
