I'm in the early stages of designing a dust collection system for my home shop. My existing system, a dustpan and broom, is vastly inefficient for my setup, which includes a tablesaw, router table, planer, and various small power tools. Long-term, my goal is to plumb my shop to run ductwork to each of my three main tools from a centralized dust collector - I haven't yet mapped out a design for this, but the tool area of my shop is around 20x15, and I'd need to run to all three tools.
When doing my initial research to get a feel for the costs, I've run into a variety of recommendations for materials to use. Some sites insist that PVC pipe is the best "affordable" option, while others strongly warn against using it due to static buildup. Most of the other options I read about are more expensive, often by a significant amount, so I want to know if it's possible to save money by using PVC, or if the risks outweigh the convenience.
Is PVC a safe material to use in a dust collection system, and are there any specific precautions I need to take in order to use it?
