DeVilbiss® Five Liter Concentrator

Improved Reliability: Five year bumper-to-bumper warranty is nowstandard. Lighter: 50 pounds the reduction of 2 pounds from theprevious 515 means easier transport and handling. Quieter: reduction insound level means most people should notice a clear improvement innoise; now 48 dBa (as measured per ISO 3744 in the 515ADZ). CoolerRunning: 10 to 15% cooler around the compressor, due to improved airflow, means longer compressor life. 515ADS (with oxygen sensor) below 2½ LPM flow, the system automatically turns down its cycle resulting in(compared to the 515DS): 35% reduction in system pressure, reducingstress on compressor bearings and internal fittings; Lower temperaturethe lower heat of compression means longer cup seal life; Improvedenergy efficiency at least 15% power reduction can save patients $45 to$60/year in electricity costs (at $0.09/kWH, used 24 hours/day). Thenew rotary valve is designed for durable, quiet performance. Lifetesting shows exceptional reliability for 10 million cycles (over 5years of average use @ 5,000 hrs/yr). Introducing the DeVilbiss/GSEcompressor: evaluated by accelerated life testing, shows exceptionalprojected life. Along with the Thomas Nexus compressor (both found on515A models), we provide unsurpassed compressor reliability. The 515Auses a simple, reliable, predictable operating system which lowersthe cost of ownership. A fixed, recessedhumidifier port is very convenient and helps prevent humidifier bottleand connection breakage.
