Hello Group, I have one of the Delta 3/4 hp roll-around dust collectors. (For those unfamiliar with this model it has the motor/blower set on top of a 30 gallon can and exhausts though a cloth bag. It has served me well except I'm certain it allows some fine dust to be dispersed throughout the room. One thought I had was to run the ehaust to a window mounted flange but this would pump a lot of warm air outside. I'd prefer to add a second stage if possible. Any suggestions- both generic or commercial are welcome. Since I just upgraded my shop equipment to include a a 15 inch planer plus a new table saw and jointer I'm having serious thoughts about making my DC stationary and serving all equipment instead of rolling it around as I've done in the past. Thanks in advance for your comments,
Marc
