Sundström SR307 Supplied-Air Regulator (Each)

The Sundström SR 307 is a belt mounted supplied-air regulator that sits between an external air supply, such as a compressor or cylinder, and a suitable Sundström respirator, hood or shield. Many Sundström half and full face masks take a compressed air attachment that fits like a filter, turning them into positive pressure respirators with no permanent changes to the mask.
