The Rhythm Healthcare TOC3 Transportable Oxygen Concentrator is designed for users who need dependable oxygen support with the flexibility of both continuous flow and pulse dose delivery. With continuous flow settings up to 3 LPM and pulse dose settings from 1–10, the TOC3 helps bridge the gap between stationary home concentrators and smaller portable units.
This unit is considered transportable rather than ultra-portable, meaning it is heavier than many small portable oxygen concentrators but offers stronger flow capabilities and more versatile use. Weighing approximately 17.2 lbs with the battery, the TOC3 comes with a cart and carry bag to make travel and movement easier.
Battery duration varies by setting, with up to approximately 6.6 hours on pulse dose Setting 1 and up to approximately 1.2 hours at 3 LPM continuous flow. The TOC3 is also approved for use during sleep in continuous-flow mode only, making it a helpful option for users who need oxygen support throughout the day and night.
