1-3 liters per minute at 90% +5.5/-3% (VisionAire 3) ⅛ -2 liters per minute at 90% +5.5/-3% (VisionAire 2) (Based on 70°F [21°C] at sea level) Accuracy: ± 10% of indicated flow setting, or ± 200 ml, whichever is greater. -
Page 11: Description Of Operation
2.0 Operational Check and Oxygen Concentration Test 2.1 Description of Operation Air is drawn into the VisionAire Oxygen Concentrator. For overall, sound efficiency, before air enters the compressor, it passes through the unit’s intake muffler. Pressurized air then exits the compressor and moves to the valve manifold. -

Page 13: Instructions
3.0 General Instructions 3.1 Instructions It is important that patients thoroughly understand how to operate the AirSep VisionAire unit. This enables proper treatment as prescribed by a qualified, licensed health care provider/physician. If patients experience any discomfort or the unit alarms, they must notify their licensed health care provider/physician immediately. -
Page 14: Patient, Provider, And Routine Maintenance
AirSep does not require any preventative or routine maintenance on the VisionAire concentrator. VisionAire’s unique design and technology allows for a virtually maintenance-free oxygen concentrator. You do not need to perform any maintenance as long as the VisionAire unit remains within specifications at the desired flow rate. -
Page 15: Components
Since this drop in oxygen production occurs over a long period of time, preventative maintenance on the compressor is not required. You can continue a patient’s therapy on the VisionAire unit as long as that unit’s oxygen concentration level at the prescribed flow rate is within AirSep’s specifications. -
Page 16: Compressor Replacement
Sound Level The condition of the compressor’s cup seals, bearings, and other components can result in an increased sound level. If the compressor’s cup seals or bearings wear to the point that they become noisy, the concentrator may become noticeably louder, therefore compressor service or exchange may be required. -
Page 17: Capacitor Replacement
The VisionAire uses five two-way solenoid valves: two feed, two waste, and one equalization. Each valve has an open (energized) and closed (de-energized) position. As the VisionAire operates, two or three valves are always energized. The solenoid valves of the VisionAire unit require no scheduled maintenance. - Page 18 attached to coils for easier installation. ( Please refer to the Valve Wire Harness drawings WH105-1 located on page C in the Appendix section of this manual as needed) Care must be taken when removing and installing valve coil retainer clips.

4.5 Sieve Beds The VisionAire unit utilizes two sieve beds each containing molecular sieve. The unique property of molecular sieve enables it to physically attract nitrogen when air passes through this material, thus producing high concentrated oxygen. -
Page 20: Cabinet Fan
4.6 Cabinet Fan The cabinet fan pulls ambient air into the VisionAire unit. As this air is drawn in, the air cools internal components (including the compressor) and exits out the bottom of the unit. 4.6.1 Cabinet Fan Replacement Periodic adjustment of the compressor enclosure may be necessary during this process. -

5. Disconnect the wire connectors labeled AC Power and PowerSw from circuit board. (If equipped with an O2 oxygen monitor, also disconnect wire connectors labeled O2 LED and Sensor). 6. With adjusting compressor enclosure (alternating pulling out top and bottom), gently remove the compressor enclosure from the center section of unit by sliding it out through the front. -
Page 22: Circuit Board Replacement
The Printed Circuit Boards (PCBs) contain components that are sensitive to electrostatic discharge (ESD) and can damage the board if not handled properly. As when handling any ESD-sensitive PCB, observe standard ESD safety procedures. 4.7.1 Circuit Board Replacement Circuit Board Removal To remove the circuit board, follow the steps below: 1. -
