For use with a powered respirator or compressed-air supply, the SR 530 Sundstrom respirator hood is a comfortable and lightweight face protection shield with a neck cape for protection from debris and dust. It comes with a fixed, flexible breathing tube, connecting to a filter fitted respirator and carry's breathable air to the wearer in hazardous working environments. The visor is made from cellulose acetate and provides protection against chemical splash and impact, while the continuous airflow keeps the visor demisted to maintain superb vision.
