BLS® 8400 Half Face Mask

The BLS® 8400 Half Face Mask is a ready to use and maintenance-free mask that combines the simplicity of disposable products with the protection of the reusable ranges, offering easy to use, certified protection against both gases and particles.

    The quality of the activated carbons used by BLS for the filtration of gases and vapours meets high standards of safety ensuring excellent filtration performances. 

    The facepiece is made of durable and hypoallergenic thermoplastic rubber for increased comfort.

    The shape of the mask offers a perfect seal without any unpleasant pressure on the nose or mouth of the user. The compact size of the mask and the lower positioning of the filters reduces interference with the visual field, allowing for higher visibility.

    The external layer ensures the protection of the filtering material from dirt, dust and liquids as well as the normal mechanical stress due to prolonged use, thus extending and preserving filtering efficiency and making the device safer.
