Weighing a mere 3.3 lbs, the Rhythm P2-S3 portable concentrator is as light as it gets. Its feather-like weight makes it an ideal companion for daily activities and travels, ensuring you never feel weighed down by your oxygen needs. Measuring just 3.4” W x 6.2” D x 6.7” H, it's small enough to fit in a tote bag, yet powerful enough to meet your oxygen needs efficiently. The protective carrying case with shoulder strap enhances comfort and keeps both hands free.

Featuring a High Absorption Sieve Bed, the Rhythm P2-S3 ensures you receive oxygen of the highest purity, maximizing oxygen concentration effectively and reliably. The compressor operates quietly, ensuring minimal disturbance especially at night. The 2.0” LCD display is bright and easy to read, with simple control functions including breath detection light, alert light, fault light, mute/audio button, flow up/down controls, on/off, and battery level indicator. No technical complexities—adjust settings effortlessly.

The P2-S3 offers single, double, or triple battery options. Single battery lasts up to 2.5 hours, double up to 4.8 hours, and triple up to 7.2 hours on setting 1.
