Just a little smaller than the M2, the M4 medical oxygen cylinder is the perfect solution for everyone who needs a convenient, light weight 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.
All cylinders are shipped empty. We do not sell or ship filled oxygen cylinders.
