As a final consideration, look at the down-time consequences on a facility when filters finally need to be serviced or replaced. A traditional baghouse will require several workers to enter the collector for filter replacement (often considered a permit-required confined space). By contrast, filters in point-of-use collectors are typically changed with relative ease from outside the collector, with filter replacement typically only requiring a single worker. The units in our earlier example could be fully serviced in just a couple of hours.
As one can see, designing a dump or rail pit dump station, with a point-of-use dust collection approach at an early stage will address a dirty situation while allowing you to save money both initially and throughout the operating life of the resulting system.
