Providing dust collection at machinery as well as self-contained ceiling suspended dust collection units will keep the shop air virtually dust free. To produce a quality product, the workshop should be as dust free as possible. If you have ever driven in a snowstorm or rainstorm you can feel for a woodworker who has his vision impaired by clouds of sawdust.  Static electricity develops when the dust particles constantly rub the plastic surface. A substantial electrical accumulation may result, which then begins to discharge into fine dust particles. It is likely an explosion will occur at some time under this condition.  The type of fan generally used for dust collection systems is a radial blade centrifugal. It has straight blades, which are, to an extent, self-cleaning. Dust collection can be done with anything from a broom and dustpan to an elegant commercial dust collection system. Before deciding on what equipment you want, you should make a decision. Do you want to protect yourself from the very fine unhealthy dust?  A good shop vacuum is a critical part of an effective small shop dust collection system. Vacuums do an excellent job of cleaning up small areas and vacuums are the only way to get good collection and avoid some little known fire risks. The problem is at low dust collection pressures air is virtually incompressible, so any small opening acts like a partially closed water valve and kills our airflow. Static Versus Flowing Electricity Static electricity is just as it sounds; the electrons are not moving, but are stationary or "static". The electrical current flowing through the wires in your home Garage Shop Dust Collection System Review is made up of electrons. In this case, the electrons are moving or "flowing". This is the only distinction between static electricity and flowing electricity. When static electricity suddenly moves, like in a spark, it is no longer static.  Q: I Dust Collection Systems For Woodworking Shops Limited have been told by an electrician that the ground wire for my dust collection system should be connected to an 8 foot copper rod driven into the ground for proper protection. My shop is all concrete, so how can I do this? A: Save your money and your sweat. This is not necessary. The primary concern of the system is to keep all points at the same voltage.
While researching how to build up my system of tubes, I noticed most of the name-brand woodworking shops sell plastic dust collection tubing. Especially during the winter, the static electricity that builds up in this plastic is incredible and -- growing up near coalmines -- I learned that flammable dust and sparks don't mix. Dec 15,  · In this article and video we installed a PVC “grounded” dust collection system into the shop. PVC is very prone to generating a static charge when air is moving along the inside of it, along with charged particles of wood and other debris. Think about combing your hair with a plastic brush. May 14,  · Air and wood particles moving through the dust collection system quickly build up static electricity charges in any nonconductive hose or piping (hose or piping not made of metal). When this static buildup discharges, it could lightly shock the operator or even ignite the flammable wood dust particles inside the piping.
