Hose length change flow/pressure?

CJNAZ · Post by **CJNAZ** » Wed Jul 13, 2011 1:12 pm

Hello all - I am considering changing from a 6' hose to a 10' hose so I can relocate my machine. Do you think the added length will make any differences in the volume and pressure of air at the mask? I am wondering if it will affect the C-Flex feature that I have gotten so use to as well. The noise from my machine aggravates me. I am a very light sleeper after the 1st four hours and if I wake up slightly I can really hear my machine. Figured if I move it away from the bed a few feet it might make the difference I desire. Let me know your thoughts.
Thanks!!!!!

Difference in air pressure will be insignifigant.

Some machines have a setting to account for using a 6 foot or 10 foot hose. I'd check into it.

Certainly it can. Esp. if you also have a mask with another 18" of hose and/or a stand alone humidifier with another 18" of hose and more volume, certainly it can. It can also affect the machine's ability to detect events when esp. using an auto.

I went thru the same thing with my 1st M series machine. The PRS1 is sposed to be quieter. Try turning off the Cflex, it is believed the changing motor speeds add to the noise. Using the humidifier chamber (empty even) can act like a muffler. Using a hose cover can muffle the noises that travel thru the hose.

I ended up putting my machine on the floor inside a clear plastic 'Sterilite' container. Not only does it help to muffle the sound when I lay the cover on the container but it helps keep the room dust from reaching the air intake.

Search this forum for Sterilite to see a picture.
