Moisture Barrier | Stedfast
Stedair® 3000 is a breathable structural firefighting moisture barrier engineered for dependable long-term protection. Its bi-component PTFE/PU barrier is laminated to a durable aramid spunlace substrate, combining liquid and chemical protection with breathability, thermal performance, and resistance to repeated laundering and demanding fireground use.
Stedair® 3000 combines microporous and monolithic barrier technologies to support protection, durability, and firefighter comfort within the complete structural firefighting protective composite.
Provides protection against blood-borne pathogens and common challenge liquids including battery acid, hydraulic fluid, Fuel C, firefighting foam, and chlorinated water.
The bi-component barrier technology is engineered to balance liquid penetration resistance with breathability to support comfort in demanding firefighting conditions.
Stedfast reports passing performance after ten wash/dry cycles at 140°F and continued waterproof performance following low-temperature exposure.
Stedair® 3000 is backed by Stedfast's four-year limited moisture-barrier warranty, subject to the manufacturer's warranty terms and requirements.
