Re: Dust Control
If a dust collector is ineffective, I wonder if its seals are intact, its intake capacity is adequate, if the velocity of its intake is adequate, and if filtering is the wrong type or is being overwhelmed with use.
If all of the engineering aspects of the unit are satisfactory the unit may need to be enclosed in a room or placed outside (if humidity is not an issue) in order to preserve needed air quality of the main space.
