The Next Generation of Quality

CAIRE’s new 5 LPM compact stationary—the Companion 5—is designed specifically for quality, performance, and reliability. The Companion 5 uses state-of-the-art technology and high-quality parts, including the high capacity sieve and compressor, to create the most durable unit on the market.

The design utilizes minimal components and internal connections. The Companion 5 reliably delivers between 0.5-5.0 LPM at high purity levels. It is sure to become the workhorse stationary of your concentrator fleet.

ultraSILENTTM Technology

The Companion 5 is perfect for the noise-sensitive patients. A patent-pending intake filter is combined with a 2-chamber muffler to reduce the intake sound. A purge muffler quiets the exhaust gas, giving the Companion 5 an industry-leading quietest purge cycle that virtually eliminates the exhaust noise event. By minimizing the intake and exhaust sounds, the low and consistent sound of the Companion 5 quickly becomes unnoticeable to patients.

autoFLOWTM Technology

The Companion 5 features a patent-pending system that adjusts the valve cycle timing based on flow rates. Lower flow rates will produce a shorter valve cycle. This leads to reduced power consumption, higher oxygen purity, lower operating temperatures, quieter operation, and reduced pressure at lower flow rates. These benefits not only improve performance and durability, but also maximize the efficiency of the major components.

The Perfect Fit for Patients

A uncomplicated patient interface features a toggle on/off switch, easy-to-read LED lights, audible alarms, and a simple rotating flow control knob. The robust metal cannula barb provides a secure connection and the humidifier bottle stand is integrated into the front panel for easy access, attachment and durability.

Simplicity of Service

The CAIRE Companion 5 was built with ease of service in mind. The 2-piece cabinet opens easily and all parts are quickly accessible. The unit contains a minimal amount of internal parts and connections. All components are quick and easy to exchange, including quick-release sieve beds. Provider maintenance is only required in 2-year intervals.

The Companion 5 Air Intake Filter is easily accessible for inspection and replacement through a panel in the bottom of the cabinet. The LED hour meter also displays diagnostic alarm codes, making service calls and diagnostics easier than ever.

*Based on an atmospheric pressure of 14.7 psia (101 kPa) at 70° F (21 °C). Operating unit outside of operational temperature range can affect performance.
