S-USA First breath version

The S-USA mask is activated by the first breath. NIOSH & NFPA approved.

When donning the first breath version of the S-USA mask it will automatically activate when the user inhales to take the first breath. A handle on the breathing valve is used to shut it off when the mask is removed.

The breathing valve has a positive lock to the mask providing a secure connection at all times. After preparing and connecting the mask to the breathing valve there is no risk for unintentional disconnection.

The mask and breathing valve design is very compact with no protruding parts which gives unrestricted visibility and reduce the risk of snagging and mechanical damage. The silent operation of the mask gives minimal noise interference and excellent communication possibilities.

An integral bypass with a large easy to use handle can be used to temporarily increase the air flow to the mask. The wireless HUD is installed in the mask without the need for any additional parts or tools.

  • Secure postive lock connection of the breathing valve to the face mask
  • Demand controlled and activated from inner mask providing excellent breathing performance
  • Prepared and compatible with voice communication systems, "Heads-Up Display" and spectacle kit
  • Ergonomic head harness with easily operated buckles

 

There are two variants of the mask, including rubber head harness or textile ("Spironet") head harness. Both variants are available in four different sizes, Small size (S), Medium size (M), Large size (L) and X-large size (XL).
