Should I ground my dust collection hose?

 Print this!

It is always a good idea to ground a flexible hose, especially if the hose is used in an application where there is a chance of static build-up, i.e. powder, pellet and dust applications. Flexaust offers three flexible static dissipative hoses that are specifically designed for this purpose.  FlexStat®, FlexStat® CR and FlexStat® 60 are manufactured with a specially formulated static dissipative polyurethane material and an embedded copper grounding wire. Every piece of hose is delivered with exposed wire on the end for grounding purposes.
