Availability: ,

Unique Group supplies HVR 4401, Underwater Oxygen Regulator, a two-stage device that provides a consistent flow and high amount of oxygen for underwater burning. According to research, cutting efficiency is more dependent on oxygen flow than on oxygen pressure. This basic criterion is met by a high volume regulator. Furthermore, the device is developed and constructed for ease of use, optimum efficiency, and long-term durability. It fits the industry standard of European and American cylinder valves and connections.
