Machine noise

I just got back from a trip, and my Phillips respironics system one 560 APAP is making a whining noise. It's a little over 3 1/2 years old, 9000 hours. With some guidance, I might be able to fix it, but I'm thinking about a new one. I think i can get a new one just like it for about $400, or maybe i should consider a newer model? I have been happy with it, except I might like one that's quieter in general. So I'm looking for suggestions. Once i get a new one, I will probably fix the old one as a spare. My pressure runs around 12, and I'm usually around an AHI of 1.0. I use sleepyhead. Thanks! Jim

Clearly, if you get a new machine, you should get a current one. Not a bad idea to keep a spare on hand.

Hi jim22,

I started with a PR 551 seven years ago. After 8700 hours, it started making a bit of noise. I too decided to go for a newer model, so I bought a PR 561.

A couple of months later, I sent the 551 in to Philips Respironics UK. If it could be reasonably repaired, I'd have it as a back up.

They inspected it, and replaced the blower. For about US $150, plus taxes.

Then after 4500 hours, the 561 started to make a noise. I sent it in. Same thing - all it needed was a new blower.

I'd have liked the 561 to have lasted a bit longer before it needed any attention. And blowers do seeem to be that generation of PR machines' weakness. On the other hand, this make is what I'm used to. And since the cost of a new blower is (to me) reasonable ...

Thanks, Rick. I saw a similar post when I searched. I am interested to get some feedback from some folks that have upgraded from the system one to the dreamstation. Does it seem nicer to use or give better results? Just from looking at it, I like the layout of the system one better, with the controls on top and outlet on the right, but if the dreamstation is really an improvement, I could go for it.
