dust collector duct

[klarenbeek]

A large cabinet shop is installing a new dust colleciton system, extracting fine sawdust only, no other materials such as faux stone will be in the system. For duct gauges, 2012 IMC has a table in section 510 with the categories of: Nonabrasive, Nonabrasive/abrasive, and Abrasive. Which one of these three clearly defined categories would be apropriate for fine sawdust?

I'd say straight non....from my firsthand experiences with sawdust...I have never dealt with it codewise....

First column for non abrasive

Thanks for the input. Been a few years since I dealt with a dust collector, and that well-defined "abrasive/non-abrasive" category made me second guess myself.
