Just slightly larger than the M2, the M4 medical oxygen cylinder is a great solution for anyone who needs a convenient, easily transportable medical oxygen supply for a short amount of time.
This cylinder weighs under 3 pounds and is only 12 inches in length. Using the RESOURCE v.2 pneumatic conserving device this cylinder can supply just under 5 hours of oxygen or just under 11 hours using the SOLO2 pneumatic conserving device.
This cylinder comes with either a standard post valve, toggle valve or Z valve. Please make your valve choice above.
