Dynarex 5L Stationary Oxygen Concentrator

The integrated OPI tracks oxygen purity at the output and alerts when concentration falls outside the therapeutic range. This is the same indicator referenced on the Dynarex Resp-O2 product page and visible from the front control panel.

Designed for 24/7 stationary oxygen therapy at home or in long-term care. The continuous-flow design delivers a steady prescribed rate without pulsing, which is what most physicians order for sleep, rest, and high-need patients.

Dynarex specifies a 37-pound weight with four rolling casters and a top grip handle, so it moves easily from room to room without dominating the space.

Ships with the humidifier bottle connector so a humidifier can be added when the prescribing clinician recommends humidified oxygen. The humidifier bottle itself is sold separately and is commonly added for higher flow settings or dry environments.

Plugs directly into a grounded US 120V wall outlet. No adapter is needed for typical home use. Avoid extension cords or surge strips, as the manufacturer manual notes continuous-use medical devices should be on a dedicated grounded outlet.

Dynarex lists standard operating altitude up to 7,500 feet without performance degradation, with an optional configuration extending up to 13,123 feet for users at higher elevation. Confirm altitude requirements with your prescribing clinician if you live above the standard range.

A manual reset button acts as a built-in circuit breaker. After a power surge or overload, the unit can be reset without service, so therapy resumes with a single press rather than waiting for a service visit.

The 33950 is classified under HCPCS code E1390, which is the standard code for stationary oxygen concentrators used in US insurance and Medicare documentation. Confirm coverage with the patient's plan and DME provider before purchase.

Federal law restricts this device to sale by or on the order of a physician. A valid prescription that specifies flow rate and use schedule is required before Sleeplay can ship the unit.
