concentrator woes

**franklin sankar** · 12-28-2016, 10:48 AM

I have a visionaire V airsep concentrator. Can someone please tell me where the filter is located.
I am getting a loss of oxygen sort of like in pulses. I blocked the outlet line with my thumb and the ball fell and pressure built up. so maybe no serious leak

Hope the pic attaches if not will try again.
Also any one found a repair/service manual on line. I can only find Visionaire 2,3 manual not V or 5. and the patient manual for V only not the repair manual.
I opened the front of the unit and could not find the filter.
Thanks for your help, this is driving me crazy.
Regards
Franklin

if your o2 is delivered in pulses the solenoid valves most likely need to be replaced. if you follow the lines from the compressor they will lead to the filter, one line will go to the valves and the other will go to the filter. some machines have no filter at all. i believe the valves in these machines are not air operated so if you o2 output pulses its not caused by the compressor feed pressure, compared to the resperonics machines. the resperonics have air operated valves so if the compressor starts under performing the valves will not actuate.

You all are the greatest. Thanks so much. I was looking for something that don't exist.
The manual in the reply is an operations manual. I was looking for the resistance value I should get when I pull out the plug and measure the resistance between the pins of the plug with the power switch on.
Thanks again.
