Hot Shield® Model HS-5 is an extremely heat & flame resistant respirator housing for the Drager Xplore 3500 Half Face Respirator. The HS-5 has been designed for firefighters in wildland/brush firefighting operations, yet will work in any thermal challenging environment. The HS-5 is constructed of CarbonX®, the only inherently nonflammable fabric in the world. This combination offers a high degree of filtration, the ability to fit test individuals and extremely efficient air exchange. This combo is small and very light; a real plus for wildland firefighters who have to carry so many items these days. Hot Shield USA makes the HS-5; we do NOT sell the Drager Xplore 3500. You must purchase that through a Drager dealer. For example, one of our dealers in New Jersey is All Hands Fire Equipment.
