Designed for 24/7 use

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.

Zen-O™ can deliver up to 2 litres per minute of oxygen in either pulse or continuous flow. Zen-O™ is supplied with variety of accessories, including a carry bag and a pull cart for increased mobility.

Zen-O’s practical and robust design offers greater operational efficiency and low cost of ownership for home oxygen providers. Zen-O™ is designed with a field replaceable sieve bed. The sieve bed is an important part of the device and enables Zen-O™ to produce oxygen. Overtime and depending on operating conditions the sieve bed may need to be replaced. The Zen-O™ sieve bed can be exchanged easily using simple tools in under 5 minutes, saving time and money.

Rate Responsive Therapy (RRT)

Zen-O™ automatically responds to a patient’s breath rate. For example, if the patient climbs some stairs and the device detects the need for more oxygen, it automatically increases the amount delivered to ensure they remain saturated.

Flexibility To Go With The Flow

Weighing just 4.66kg (10.25lbs), the Zen-O™ offers lightweight portability, which means patients can carry on with their lives unrestricted. With its intuitive buttons and clear LCD display, many of the ultra-reliable Zen-O™ is simple to operate in all kinds of environments.



Each Zen-O™ device is supplied with a carry bag, battery, AC/DC power cables, accessories bag and a pull cart.
