Liquid Oxygen Portables

At ROCKY MOUNTAIN OXYGEN REPAIR in Littleton, Colorado, you find new and refurbished liquid oxygen systems. All with warranties. The portables are filled with liquid oxygen from the base for freedom of movement. 

HELiOS™ Plus & Marathon®

Although tiny and incredibly lightweight, the HELiOS Plus is powerful, lasting up to 9 hours but weighing only 3.6 pounds fully filled. CAIRE, Inc.'s HELiOS Marathon Portable Oxygen Unit gives oxygen therapy patients unprecedented freedom: It lasts up to 22 hours between refills, yet weighs only 5.6 pounds fully filled! The HELiOS Marathon portable unit lets patients be out all day. Whether they want to visit friends and family, shop, travel, fish, or golf - patients can have long lasting freedom without needing to refill their lightweight oxygen portable or bringing along extra oxygen cylinders. 

Continuous Flow/Demand Flow Versatility

While other portable oxygen units have limited continuous flow operation, the lightweight HELiOS portable units feature multiple settings for continuous and demand flow modes. Now continous flow patients can enjoy the "no spill" design and portability the HELiOS system is known for. 


The lightweight Companion 1000 Portable Liquid Oxygen Unit and Companion T High-Flow Portable Liquid Oxygen Unit offer oxygen therapy options for patients who require continuous oxygen flow. The reliable Companion 1000 unit combines comfort and convenience in a durable, lightweight, simple-to-use portable liquid oxygen system. The Companion fills quickly and easily from any Companion, Liberator, or HELiOS Universal Reservoir. The Companion T unit offers the same design features and lightweight package, plus extended liters per minute settings for higher flow rates.

Liquid Oxygen Bases

Companion Reservoir
Companion Reservoirs 21, 31 & 41
Companion Liquid Oxygen Reservoirs offer high quality and reliability. Companion 21, 31 and 41 models have capabilities of 21, 31, and 41 liquid liters of oxygen, respectively. The proven vessel design of these reservoirs is rugged and easy to use. Low maintenance and long life make them cost-effective to own. The Companion reservoirs are compatible with the line of lightweight Companion Portable Liquid Oxygen Units.
HELiOS Universal Reservoir
HELiOS U36 & U46
CAIRE Inc.'s versatile liquid oxygen reservoir works with our popular lightweight HELiOS Plus and Marathon liquid oxygen units, as well as Companion style portable liquid oxygen units. Available in two sizes, the flexible HELiOS Universal Reservoir can help you make optimal use of inventory to reduce your operating costs. The reservoir keeps delivery costs to a minimum because it is designed with the same low-loss evaporative control system used on the original HELiOS reservoir. 

The HELiOS Universal Reservoir can also provide oxygen directly to patients using the external Flow Control Value.
