COMPRESSED AIR ATTACHMENT SUNDSTRÖM SR 307

Compressed air device for half-mask and full-face respirators. The SR 307 compressed air add-on unit is designed to be attached to Sundström half-mask and full-face respirators. The combination forms a breathing apparatus intended for connection to a compressed air supply as a continuous-feed breathing device. The SR 307 is an add-on unit that allows the facepiece to be used either as a filter respirator or as a protective device connected to a compressed air supply. The compressed air add-on unit is intended especially for heavy-duty and long-duration work and in situations where contaminants have poor warning properties or are particularly toxic. The SR 307 is manufactured from a material that does not cause sparking due to static electricity, so the hood can be used in explosive and fire-prone environments. It includes a flow meter and a warning whistle for intermittent and continuous monitoring of airflow. A control valve for attachment to the user's belt is included.
