COMPRESSED AIR ATTACHMENT SUNDSTRÖM SR 507

Compressed air unit for hoods, facepieces, visor helmets, and half masks. The SR 507 compressed air accessory is designed to be connected to Sundström's SR 520 / SR 530 / SR 561 / SR 562 hoods, SR 570 / SR 540 EX visors, SR 900 half mask, SR 590 welding helmet, visored SR 580 helmet, SR 584 / SR 580 welding helmet / visored helmet. The combination forms a breathing apparatus designed to be connected to a compressed air unit as a supplied-air respirator. The SR 507 is an accessory that allows the facepiece to be used either as a protective device connected to a compressed air unit or as a motor-powered air-purifying respirator (PAPR). The compressed air accessory is intended especially for heavy and prolonged work and environments where contaminants have poor warning properties or are particularly toxic. The SR 507 is manufactured from materials that do not cause sparking due to static electricity, so the device can be used in explosion- and fire-prone environments. It includes a flow meter and a warning whistle for intermittent and continuous monitoring of airflow. It also includes an adjustment valve that can be attached to the user's belt.
