AirSep FreeStyle In Use

A New Class of Oxygen Users

FreeStyle offers a uniquely efficient, ultra-compact, and flexible pulse-flow delivery system. Through this miniaturization into a wearable unit, a new class of oxygen users has emerged: Self-reliant individuals who are satisfied only when experiencing life to the fullest. For some that means travel across the country or travel around the world. For others, it’s doing the garden chores on the weekend, unrestricted by time. For still others, it is the exhilaration in attending a grandchild’s outdoor soccer match – carefree – or even trying your footwork at soccer yourself once again.

Now oxygen patients just like you are experiencing total freedom for the first time – all with the help of FreeStyle. And only AirSep Corporation, a leading manufacturer of high-quality medical equipment for home, hospital, and clinical use, makes this possible. AirSep is the most experienced oxygen manufacturer, including the development of the industry’s first POC. AirSep POCs are permitted on board commercial airlines, which means your journey with oxygen is wherever you wish to go.

Flexibility in Power is Key

FreeStyle runs on an internal, rechargeable battery. You can also use it while it is recharging — at home or in a motor vehicle. Peace of mind awaits you in realizing that you will never need to rush home again to change a cylinder or to obtain a refill of oxygen. FreeStyle enables you to enjoy living — wherever you are. You can easily power up from any standard AC or 12-volt DC outlet in any location. The 100-250V, 50/60 Hz unit is designed to operate anywhere in the world; just simply change AC power cords when needed. The FreeStyle POC includes both an AC power cord and supply, as well as the DC power supply for recharging when in an automobile, motor boat, or other recreational vehicle.

AirBelt™ for an All-Day Adventure

The FreeStyle unit’s internal battery enables up to 3 ½ hours of use between recharges – plenty for the majority of oxygen patient activities, and ample time also to move from one power source to the next. However, for those occasions when more time is needed away from an available power source for extended activity – FreeStyle’s optional AirBelt serves as your trusted companion. Designed to be worn on the waist and connected to the FreeStyle unit, the featherweight AirBelt provides hours of extended battery duration. In fact, depending on setting, with AirBelt at your side, you can experience up to ten hours of ambulation between recharges.

Fashion and Function

Another unique attribute about FreeStyle is its design for “fashion and function.” No other oxygen system offers such an advanced concept for the contemporary oxygen user. The “basic black” style of bag with comfort shoulder strap is a fashion statement unto itself. It is designed to look unobtrusive, and tailored like a small video camera case. This bag comes standard with the FreeStyle oxygen concentrator, and the optional AirBelt in “basic black” completes this fashionable oxygen ensemble to maximize battery duration while mobile.

Unleashing Your Potential

When you have no boundaries, you have no limitations to your potential. Caregivers and clinical professionals are recommending FreeStyle as the lightweight choice when an oxygen user clearly
needs a better solution than ordinary, refillable oxygen systems. FreeStyle can be the ideal selection for those ready to give up lugging around extra tanks, or those not able or willing to sit home for hours trying to refill their own cylinders. And there’s simply no more waiting around for the delivery truck to re-supply oxygen again and again. If you can see yourself, your patient, or your loved one in any of these life moments whether at work or at play – exercising, shopping, dining out, completing errands, or visiting with friends and family, then it may be the right time to find out how the AirSep FreeStyle can be the ticket to a new kind of freedom.
