  • Reliable and Technologically Advanced
  • Built to Last
  • Eco Friendly

Reliable and Technologically Advanced: A high-performing stationary with an advanced design built specifically with longevity and durability in mind, the Companion is not only simple to use for patients, but its advanced technology offers a low total cost of ownership.

Built to Last: Reduce costly breakdowns, after hours calls, and downtime with the unique design of the Companion 5. It features a highcapacity compressor and high-capacity sieve beds equipped with proprietary moisture-resistant MGB SecoBlen sieve mixture. This unique design prolongs the life of the major components. Patent-pending autoFLO technology (variable valve timing based on flow rate) was created specifically to help optimize performance and extend the life of the major components. It reduces the wear on the compressor by 25% at 2 LPM, decreases the operating temperatures to improve cooling, significantly reduces power draw, and improves the overall life of the concentrator.

Eco Friendly: Drawing only 285 W at 2 LPM thanks to the reductions of autoFLOW Technology, the Companion 5 gives patients significant savings on their electrical costs, and helps to decrease wear on the electrical components. Ease of Service With lengthy 2-year maintenance intervals, there is no gross particle filter to clean and no 9-volt battery to replace. The intake filter is easily accessible without opening the case through a filter door. The large and easy to read hour meter displays diagnostic alarm codes. These features help reduce after-hours calls and help over-the-phone diagnosis.
