An oxygen concentrator is an electrically operated device. It draws in room air, then removes the nitrogen and delivers the concentrated oxygen to you through tubing to a nasal cannula.

Wright & Filippis offers the following products, including both stationary and portable concentrators:

Five Liter Concentrator
	The Five Liter Concentrator offers improved filtration, longer bed life and excellent oxygen purity. The Concentrator is lighter weight and more compact than most 5 LPM concentrators. A fixed humidifier port and recessed humidifier pocket helps prevent bottle and connection breakage. Pressure-compensated flow meter permits use of long cannula while maintaining accurate flow setting.
iFill
	The iFill Personal Oxygen Station represents the latest in portable oxygen convenience, providing unmatched flexibility and ease of use. The iFill unit extracts purified oxygen from room air using standard oxygen concentrator technology. Connectors on the cylinder and iFill unit simply click into place. An M6 cylinder can be filled in just a little over an hour.
Eclipse
	First there was stationary. Then there was portable. Now there is the Eclipse, the independent system that defines a new category of oxygen device. Designed to perform as both a stationary and a portable device, the Eclipse is engineered to meet the changing demands of the oxygen industry. For patients, the Eclipse presents an opportunity for spontaneity and more active life both at home and on the road. This item is also FAA approved for air travel.
