A fullface respirator which is light and comfortable to wear, even for long periods of time without becoming tired or stressed. A wide sealing edge provides a snug fit to the face and adjusts easily for wearer comfort. Can be worn with a helmet and hearing protectors. The facemask has a wide field of vision with inhalation air directed across the inside of the visor to prevent misting. One can talk clearly with the respirator on because of a protected speech diaphragm. The exhalation valve is of a secure construction and keeps the carbon dioxide level inside the mask at a minimum. The facemask materials are resistant to a wide range of chemicals. Applicable filters are a separate order.
