New Series M water chamber

I have the Respironics A-Flex and when my last chamber was replaced, they sent me a brand newly designed chamber. The plastic appears to be harder, possibly Eastman which may mean less BPA issues.

The chamber also has a new latching system which is a breeze to close. Well, heck - I'll just take a picture and show you (sorry about the glare on the second one):

There is apparently a newer chamber design than this...at least that's what my DME told me. It's called a J-tube and they say it has fewer leaks than the older side-by-side openings. My husband is out of town, so I can't photograph his until he comes home and my rental unit has the side-by-side style. The J-tube chamber looks to be the same clear plastic as the side-by-side, though. The humidifier unit is has different internal tubing, too.

I do like the latch, although it's the only one I've used....

Yes the new-es chamber is the J-tube, also the new HH is 12 V now, instead of 120v. I have the new HH and chamber and both work really good. I have taken mine apart several times now without any problems with leaking, but I also have the old style, side by side square tube chamber with the old sliding latch and it never leaked either, must have gotten a good one. I do like the new designed latch but wished that they had made the chamber a little bigger. I never run out of water but I only use 1 or bypass. I know that others run their units on higher settings and occasionally run out of water, that seems to be the biggest problem with the new chamber compared to the old tank chamber, the unit is more compact though.

Regards,

Dan

Oh! I look forward to seeing the J-tub : ) I'll take it to my DME.

I didn't have any problems with leaking on the older slide latch either. This one is definitely easier to latch though and the redesign of the rubber seal doesn't leave it as open to being disturbed or damaged.

Um what, Guest? The side-by-side chamber is still available to purchase because people are still using that model. The one they're calling "staggered" is also called the J-tube.

The leak my DME talked about was the vapor, not the water chamber. Sorry I wasn't specific before. She said the side-by-side fittings didn't meet up with the other side on the humidifier well and the vapor leaked, wasting humidification.... The J-tube has better fittings because they actually go one inside the other.

I thought the J-tube type was the newest for the Normal CPAP M Series, correct?

The J-tube is part of the humidifier, not the flow generator. I'm guessing it can be used with both regular CPAPs as well as APAPs. Maybe even BiPAPs...I don't know if they need a different type of humidifier. But yes, it is the newest humidifier type which is meant to go with the M series.

My DME (on the phone) was going to send me a new HH chamber, the new staggered one. I told him no, that my humidifier uses the side by side square-ish ones. He says no-problem the new staggered chamber fits in the old style humidifier. I told him no, I don't think it does. He repeated several times that it would and I kept telling him no it doesn't. To convince me, he tried to put the new style chamber in an older humidifier he had on his desk... 30 sec later... Oh, gee, I guess you're right it doesn't fit. I'll send you the updated side-by-side style chamber.
My DME is really sad...

Well if the new one runs on 12V it might be a good investment -- I have both the old style M-series HH and the HC-150. I'll use the HC-150 when I have a place to put it next to the bed.....A 12V HH would catch my interest....

If it runs on 12V it can be run on a battery.....anyone know what the current draw is??? I can use my APAP for 3-4 days on the battery before it needs recharging (it'll really go for a week but I don't like draining the battery below 50% capacity). Being a heater I would suspect it draws a bit of power.....(I know, I know -- I could just go out and try to look it up, but hey what fun would that be???? )

Thanks

looks like they changed the design quite a bit. That o-ring deal didn't work, o-ring was too small, the new gasket looks much beefier and a compression design, as long as the tank doesn't distort.

With the first tank, if you took the lid off for cleaning as recommended it would leak like a sieve in no time, inside the humidifier chassis.

They should have recalled that tank and replaced it with the one in the center, those are all going to eventually fail and by the time the owner realizes it your night stand is ruined from water damage or you have water inside the chassis.

the Sleep Easy design appears a lot better than the M series, but they don't offer it in the auto version, only CPAP, they must have farmed out the design of this one to the guy that designed the tank:



If I was Respironics Product Manager, I'd have that Sleep Easy machine loaded up with the Aflex Auto firmware, breakout AI and HI from AHI, add a software controllable LCD and button backlight, dump the SmartCard altogether and put on a simple USB port and the thing would sell like hotcakes. Make the sleep data a text file and show up on any computer as a pen drive, let people create any report they want.

Snoredog, that was probably the one thing you've said over the last several months that made any resemblance to sense.

gasp, here is a picture of the J-tube type. This is what I have, in my 3 month old machine.

At 12 volts we found it draws between 350 - 500 mA (with heater on). However, hubby noted that these numbers are an estimate as he didn't leave his fancy meter on it - it was just an amp meter (or some such thing). Can you tell I didn't pay too close attention when he started to get all technical : )
