Due to State and Federal Law, we sell Syringes and Needles only to the Medical Facilities. Now #515ADZ * The DeVilbiss? Five Liter Concentrator (w/o OSD) is designed to be reliable, quiet, energy efficient and lightweight * 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 ? 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 * A fixed, recessed humidifier port is very convenient and helps prevent humidifier bottle and connection breakage * The pressure compensated flow meter permits use of a long cannula while maintaining an accurate flow setting. The flow meter knob can also be locked for added patient safety * Built to meet the requirements of HCPCS code: E1390 * Product Weight: 50 lbs * Product Width: 16 in * Product Length/Depth: 14 in * Product Height: 27.75 in * Shipping Weight: 58 lbs. Delivery Rate 1-5 liters per minute (1/2 liter increments) * Oxygen % 93% at 1-5 LPM (+/- 3%) * Operating System Timed cycle / pressure swing * Sound Level 48 dBA (515ADZ) Pressure 8.5 PSIG.
