Is PVC pipe anti static?
This PVC (polyvinyl chloride) hose features an anti-static resin in the hose wall. The strong, PVC helix resists crushing and deformation but is still flexible enough to get into tight places.
Does PVC create static?
The energetic material is loaded into a length of the pipe, along with some sensors and other components. The material is ignited, after which the pipe is destroyed. The static spark concern is only during the loading process, when the energetic material could be ignited prematurely.
Why is PVC not used for dust collection?
The main reason why PVC pipe is not recommended is the buildup of static electricity and the high risk of explosion. Plastic pipe systems are not designed for dust collection use. A necessary diversity of fittings to meet design requirement does not exist.
What kind of pipe to use for dust collection?
My own shop dust collection system is piped with 4″ plastic sewer pipe, which, by the way, is ABS, a plastic both tougher and more flexible than PVC. That’s the same plastic used in the old days for telephones, back when Western Electric made them to last fifty years no matter how often they were dropped. Ah, those were the days.
Why are plastic pipe fittings improper for dust collection?
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. With a metal dust collection piping system, static electrically won’t develop. Elbows and other various fittings are properly designed for conveying dust.
How big of PVC pipe do I need for sawdust collection?
If it is a saw that will produce a large amount of sawdust, you should, of course, use bigger pipe. PVC pipe used for a system like this should not exceed 6″, though, as larger pipe sizes will decrease the power of the central system. The actual construction of this system is highly modular and will be unique depending on the space.
