Metal vs PVC

INTRODUCTION

Your first critical design decision is the type of ducting material.  Ideally metal ducting is preferred over plastic but if low cost is your primary concern PVC pipe is hard to beat.  Of course the DustDog ecosystem support either or both!

The biggest issue most people mention for PVC pipe  is static discharge risk.  For commercial and industrial applications this is a significant factor and regulations might even prohibit PVC piping.

PVC is non-conductive and accumulates static electricity. This can result in shocks when touching pipes  However if you can’t afford metal ducting we can show you how to work around this problem by grounding your plastic pipes.
