The 8000 Series Respirator conforms to the contours of your face. It seals comfortably and remains sealed, even while talking. Plus, the seal is extra-wide, so it fits more facial types. Whether you use gas/vapor cartridges or disks/filters, the 8000 weighs less and the weight is distributed evenly, without pressure points. The low profile, compact design provides an expansive field of vision and makes the mask well suited to be worn under welding helmets.
