The static discharges, if any, are insufficient to ignite even the worst dustair mixes.The wire is of no value.The reason that the static builds up in the first place is that the plastic is an insulator.Running a wire through a plastic insulator tube only grounds the part of the tube it touches.
In preparation i purchased a rockler dust collector to get more cfm than my festool ct.When i installed a dc in my shop i ran bare wire through the plastic pipes, using lee valleys grounding kit, which looks moreorless the same as rocklers.Logged ryanjg117.
Plastic pipe systems are not designed for dust collection use.A necessary diversity of fittings to meet design requirement does not exist.Also, plastic pipe elbows have a very short radius and plastic tee fittings are improper for dust removal.It is these types of problems that lead to an inefficient dust collection system.
Anyone who has used flexible plastic hoses to connect shop tools has felt the effect of the static buildup, unless the hose has a reinforcing wire that can be grounded to the dust collector.In the case of pvc rigid pipe, similar static charge buildup will occur and some prudent folks add a bare drain wire to remove the charge.In a workshop.
Grounding a pvc dust collection system sign in to follow this.Followers 0.That means that no matter how you try by running wires through the pipe or wrapping the pipe in wire or foil, the charge will not flow through the pipe.It is an impossibility of physics to ground plastic pipe.Consider this the insulation in the power cords.
Here is a copy of info from shop fox, a popular portable dust collector.System grounding.Since plastic hose is abundant, relatively inexpensive, easily assembled and air tight, it is a very popular.Material for conveying dust from woodworking machines.To the dust collector.We recommend using flexible hose flexhose to connect the.
Plastic pipe or pvc pipe is unsuitable for dust collection for three reasons first, plastic pipe ttings are not offered in the diversity required to meet design requirements.Second, plastic pipe elbows have a short radius, which encourages clogs and compromises system ef ciency.Third, and most important, plastic pipe is.
Grounding pvc and other dust collection myths.The only thing of concern in a dust collector are the ducts.As seen above, the collected dust pile and the collection bag are greater hazards than the ducts.Static electricity buildup in plastic pipe.Information date 19880903 ptasinshi, l.Identification of hazards caused by static.
Grounding your plastic pipe is not a safety issue.If you are concerned about getting zapped from time to time, then ground the parts that are within normal operating reach.Otherwise, forget about it.Srd pipe is a lot cheaper than smooth walled metal pipe for dust collection.Hvac metal pipe may be comparable in price, but it is crap.
Dust fittings are abs plastic for toughness and durability and come in sizes and shapes to meet almost any dust collection system requirement choose from elbows, couplings, reducers, wyes, tees, hoods and blast gates.Note when using any dust collection system, always ensure proper electrical grounding.If in doubt, contact an electrician.

Before we moved to a development, i had a large shop with nearly 200 ft.Of pvc dust collector pipe with drops to all machines and none of it was grounded.I read up for almost a year before i assembled and installed the collector system and i found that there has never been a reported fire or fire claim caused by static in a home dust dust.
Join duct and fittings with quickrelease clamps for faster disassembly and cleanout than other duct systems.Galvanized steel has good corrosion resistance.Aluminum is lightweight and has good corrosion resistance.304 stainless steel is the most corrosion resistant.For technical drawings and 3d models, click on a part number.
