Portable vs. Stationary Concentrators
View our wide selection of oxygen concentrators accessories available to buy online.
Oxygen concentrators for home oxygen therapy are available as either stationary or portable units. Stationary models are generally larger and heavier than their portable counterparts, however with increased size comes an increased oxygen flow rating. Stationary oxygen concentrators are capable of delivering anywhere from 3 to 10 liters per minute of oxygen while most portable models deliver 3 or less. Stationary models are suitable for in-home use and for patients who have been prescribed higher doses of oxygen.
Portable oxygen concentrators are designed to accommodate ambulatory patients who require a lower dosage of oxygen. These units feature optional power sources that allow them to draw power from a wall outlet, a vehicle adapter or a battery pack. Portable oxygen concentrators are especially convenient for patients who like to travel and some of them are even approved by the FAA for use while traveling by air.
