Modular industrial oxygen concentrator

摘要

An improved pressure swing adsorption device built using a modular concept and comprising a surge tank unit and a combined bed and control unit, each of those units being separately replaceable and separately usable. The valves and other controls are constructed in a modular manner and fit onto the beds such that they are readily and easily replaced without dissembling the entire control apparatus. Numerous other features and advantages are provided to all together produce a highly reliable easily serviceable and relatively low cost to manufacture device.
