ResMed Noisy (Pnuematic Block) Replacement

RE: ResMed Noisy (Pnuematic Block) Replacement
My noisy machine is actually very low in hours but several years older than the quiet one. Maybe it was subjected to ozone, or maybe there was a design and/or supplier tweak they won’t ‘fess up to. I got it at a good price and it works fine except for the noise.

You can clean the tub but you can't clean inside the machine. Use distilled or purified water.

The use of tap water in the humidifier cannot affect the pneumatic block because airflow is the other direction. It is possible there was abuse, such as not using a filter, using ozone or other problems, but the simple fact is that a certain percentage of these failed regardless of care.

Not sure what the pneumatic block is but I assume it's the motor/blower assembly. The parts for these machines are astronomical in price. 

This is probably the $185 pneumatic block:
