Zen-O Portable Oxygen Concentrator offers both continuous and pulse flow oxygen for oxygen therapy patients. The Zen O offers 2 liters per minute (LPM), meeting the oxygen demands for most patients. This concentrator is designed for respiratory disorders such as chronic obstructive pulmonary disease (COPD), providing oxygen on demand for patients both at home or on the go. Its lightweight structure and small size make it easy to bring with you in its carry-bag or pull cart that comes standard with your order.

Zen-O concentrator offers greater operational efficiency than many of the competing portable oxygen concentrators on the market. Maximum outlet pressure is 20.5 psi, able to push oxygen through extended tubing. Oxygen concentration levels range between 87 to 96 percent. Noise emission for this small concentrator is at 42 decibels (ISO 3744 standard).
The AC power adapter is able to function using from 100 to 240 volts on 50 to 60 hz systems. The DC power adapter provides for use in automobiles, boats and RV’s. A 12-cell battery will power the Zen-O for 4 hours with 2 LPM of oxygen at 18 breaths per minute (BPM) while in pulse flow mode. Add an additional battery and the Zen-O will allow you to operate away from home for up to 8 hours.

The Zen-O Oxygen Concentrator is manufactured by GCE with an easy to replace sieve bed that can be exchanged using simple tools in under 5 minutes. This can save you hundreds of dollars over other brands. Zen-O™ uses advanced technology in its construction to adjust the amount of oxygen delivered according to a patient’s breath rate. When the patient needs more oxygen this concentrator automatically responds by increasing the oxygen output
