Case study

Pacific Fishermen Shipyard

"I was getting that fresh supply within the hood, which really helped my breathing. You know sometimes when you wear just a filtered respirator, it’s kind of restricted. Once your filters kind of get clogged you start to breathe heavier and heavier to try to get that air coming in, with the Z4 I didn’t have the issue at all." - Nathaniel Williams, Welder.
