I just got a 2HP, 1550 CFM Fox Shop dust collector. It has a 6" duct. A guy at the store recommended to add a separator but it must be bigger than a regular trash can or dust will be kept airborne because of high turbulence in a small can volume and won't settle at the bottom making separator work only for bigger heavier dust particles and not for smaller particles which are more dangerous. He recommended at least 55 gallon can. The problem is that I don't have that much space available in my shop.
Does any one tried smaller cans for separator? How does it work?
Thanks, Alex
