Category: Oxygen Concentrator

Improved Reliability: Five year bumper-to-bumper warranty is now standard. Lighter: 50 pounds the reduction of 2 pounds from the previous 515 means easier transport and handling. Quieter: reduction in sound level means most people should notice a clear improvement in noise; now 48 dBa (as measured per ISO 3744 in the 515ADZ). Cooler Running: 10 to 15% cooler around the compressor, due to improved air flow, means longer compressor life. 515ADS (with oxygen sensor) below 2 ½ LPM flow, the system automatically turns down its cycle resulting in (compared to the 515DS): 35% reduction in system pressure, reducing stress on compressor bearings and internal fittings; Lower temperature the lower heat of compression means longer cup seal life; Improved energy efficiency at least 15% power reduction can save patients $45 to $60/year in electricity costs (at $0.09/kWH, used 24 hours/day). The new rotary valve is designed for durable, quiet performance. Life testing shows exceptional reliability for 10 million cycles (over 5 years of average use @ 5,000 hrs/yr). Introducing the DeVilbiss/GSE compressor: evaluated by accelerated life testing, shows exceptional projected life. Along with the Thomas Nexus compressor (both found on 515A models), we provide unsurpassed compressor reliability. The 515A uses a simple, reliable, predictable operating system which lowers the cost of ownership. A fixed, recessed humidifier port is very convenient and helps prevent humidifier bottle and connection breakage.
