GCE Zen-O Portable Oxygen Concentrator




GCE Zen-O Portable Oxygen Concentrator.

The GCE Zen-O™ is a best in class portable oxygen concentrator with pulse and continuous oxygen delivery modes for active patients requiring oxygen therapy.

The GCE Zen-O™ portable oxygen concentrator is designed to enable patients with respiratory disorders such as chronic obstructive pulmonary disease (COPD), better manage their oxygen therapy within and outside their homes.

The GCE Zen-O™ portable oxygen concentrator weighs just 4.66 kg and can deliver up to 2 litres per minute of oxygen in either pulse or continuous flow.

The GCE Zen-O™ portable oxygen concentrator is supplied with a carry bag and a pull cart for increased mobility.

The GCE Zen-O™ portable oxygen concentrator's practical and robust design offers greater operational efficiency and low cost of ownership for home oxygen use.

The GCE Zen-O™ portable oxygen concentrator is designed with a field replaceable sieve bed. The sieve bed is an important part of the device and enables the concentrator to produce oxygen. Over time and depending on operating conditions the sieve bed may need to be replaced. The GCE Zen-O™ portable oxygen concentrator sieve bed can be exchanged easily using simple tools in under 5 minutes, saving time and money.

The GCE Zen-O™ portable oxygen concentrator features breath sensitivity and Rate Response Therapy™ (RRT) that automatically adjusts to the patient‘s demands.


The GCE Zen-O™ portable oxygen concentrator delivers up to 2 litres of oxygen per minute in response to the patient’s need. Unlike other devices that deliver a fixed amount of oxygen, Zen-O™ automatically increases the amount of oxygen delivered if a patient’s breath rate rises.
