General Product Description

The Zen-O™ from GCE is an all-in-one portable oxygen solution that caters for a wide range of oxygen patients whilst maintaining a high degree of portability.

It has two oxygen flow modes, providing up to a maximum of 2 litres per minute of continuous flow and 6 pulse flow settings. Weighing from just 10.8lbs (4.66kg), the Zen-O™ is one of very few devices offering a continuous flow option where it’s possible that the unit can be worn over the shoulder. The concentrator also comes with a wheeled cart and accessory bag as standard.

Its stylish design is coupled with a simple to use interface and intuitive button operation all on a backlit LCD display.  Using advanced patented technology, Zen-O™ automatically responds to an increase of the user’s breathing rate, increasing the amount of oxygen delivered to ensure the user remains saturated.

Zen-O™ can be purchased with one or two 12-cell Lithium batteries providing up to 8 hours of use on single charge depending on usage conditions, flow mode and setting. The battery compartment can house two batteries at the same time.
