A commonly used system manufactured by Poisk uses three high-pressure composite cylinders filled to 260 Bar at 20 degrees Celsius. The dimensions of the cylinders are 19 inches (480 mm) long, 4.25 inches (108 mm) diameter, and weight under 2.7 kilograms (6.0 lb). At a two-liter per minute flow the cylinders last approximately 6.5 hours each. [7]
