The housing for the Inogen One oxygen concentrator is a polycabonate/ABS alloy called BayBlend FR3001 from Bayer MaterialScience LLC, Pittsburgh.

The Inogen One eliminates the need for tanks typically associated with portable oxygendelivery systems and is capable of delivering 90 ± 3% oxygen.


The housing for the Inogen One oxygen concentrator is a polycabonate/ABS alloy called BayBlend FR3001 from Bayer MaterialScience LLC, Pittsburgh. The housing protects internal workings of the pulse-dose delivery system from the rigors of daily abuse. The system bridges the gap between conventional floor-based units and portable devices used to treat Chronic Obstructive Pulmonary Disease. Bulky, 50-lb floor-based units and previous portable oxygen tanks both had limited capacity and often relegated ambulatory patients to a 9-ft tether. In contrast, the Inogen One concentrator weighs in at just 10 lb, is battery powered, and extends the patient's range by delivering oxygen up to 100 ft from the device.

Geoff Deane, vice president of engineering for the OEM Iogen in Goleta, Calif., says the Inogen serves as both a stationary and portable device, so it must handle potential rigorous abuse as patients work around the house, yard, or office. "Bayblend FR3001 gives strength to the device's external housing, helping to protect the delicate inner workings and extend the instrument's life." The material is halogen/antimony-free and complies with TCO 95/99, Nordic Swan, and Blue Angel standards and lets Inogen meet UL safety and fire ratings. "Flow properties were another important attribute of the resin," says Deane. "The improved flow helped the injection molder produce higher quality parts."
