The Equinox and Independence illustrate the best that modern oxygen therapy has to offer. Both machines go to 3 LPM continuous and the Equinox has three additional pulse settings. The Equinox is the smallest and lightest concentrator that goes up to 3 continuous. Weighing just 14 pounds, it is more than 5 pounds less than the Independence and almost 6 inches shorter. Both roll nimbly on their respective travel carts. The Independence cart is built into the unit while the Equinox’s attaches securely with one hand screw in the back. Both machines provide excellent battery life. The Independence uses a dual battery system which allows for one battery to be on the external charger while the other is being used for uninterrupted oxygen flow. Both can be used and charged using D/C power in the car. The Equinox has an exclusive voice warning system that delivers warnings in seven languages. Instead of just beeping the Equinox will tell you exactly what is wrong.
