Advantages The EDOCS module generates oxygen utilizing Vacuum Swing Adsorption technology. The EDOCS-120B concentrator generates 120 liters per minute (lpm) at 85 psi. The oxygen can be delivered directly from the concentrator to the hospital distribution system at 85 psi and/or supplied to the boost compressor. The built-in boost compresses the gas to 2,250 psi for the purpose of filling standard medical oxygen cylinders utilizing a cylinder-filling manifold. A vacuum pump is included with the EDOCS to evacuate cylinders prior to filling.
