5 Liter Silver Opti-Max Oxygen Concentrator

Our 5 Silver Opti-Max Oxygen Concentrator is an excellent low-cost entry into EWOT. It delivers a steady flow of up to 5 liters per minute of 87–96% pure oxygen, making it ideal for the reservoir bag method of Exercise with Oxygen Therapy. While it is not suited for on-demand high-flow EWOT (which studies such as those by von Ardenne show requires at least 8 LPM), it gives many users an affordable and effective way to add oxygen to their workouts without a large investment.The same unit is also highly popular for ozone applications. It works great as a reliable oxygen feed source for making ozonated water and ozonated glycerin at home or in small setups. Compact, lightweight, and built with the trusted Devilbiss quality you expect, this model includes the exclusive Oxygen Sensing Device for consistent purity, multiple safety alarms, and simple everyday operation. It’s the perfect value choice when you want solid performance at a lower price point.
