A well-designed central dust-collection system whisks wood dust and debris from machinery, work stations, and floor. A central collection system -- collector, rigid metal ducts, and flexible hose -- is the approach suggested and explained here. Sawdust piling up on the shop floor is a nuisance and a fire hazard, writes Sandor Nagyszalanczy. Here, he explains why he thinks a central collection system, consisting of a collector, rigid metal ducts, and flexible hose, is the best approach. He compares central collectors to shop vacuums and says two-stage systems are safer and more efficient. He discusses cyclones, separator cans, and drop boxes, and offers advice on what to do if your collector is underpowered. He also discusses filtration and air volume that’s required for small-shop woodworking machines.
