Just had a chat with a Respironics techy. Oh boy. If he is right, the motor is part of the airflow path and is a two stage affair to keep the noise down. That means that the air flows throw the first half of the motor and is then directed to the second half of the motor to speed it up further. So, in cleaning a unit inside/out (i.e. for tobacco smoke) one would have to remove the motor and clean it. Clean the 'cradle' that the motor sits in. Clean the plastic foam that surrounds the motor and then reassemble the whole shooting match. That seems to be the airflow path. In through the chunky filter and into a plastic 'tub' that contains the air pressure. Through the top half and then the bottom half of the motor (impellers) and then out into the humidifier and hose, etc. The plastic tub AND the motor would need to be cleaned as well as the plastic foam sound and vibration dampener surrounding that tub that will just soak up tobacco smoke like (what it is) a sponge. And then out the back door. I am wondering any other tobacco smoke residue would be insignificant.
Well, still looking for a shop manual for the unit so that when I tear it apart I can put it back together and calibrate it. The truth of the matter is that the first one is going to take the time (figuring out where things screw together, etc.); but from that point forward it shouldn't take very long to clean out one of these blowers as long as one stays clear of the electronics, which I gather can be removed pretty fast as it is all connectorized. Remove the tub, the motor, the foam and clean same. Allow to dry in the outdoor fresh air and sun for a few hours until bone dry. Then allow to run in the outdoor fresh air and sun for a couple of days just like the laundry. Should wind up with a better than new unit methinks. The humidifer and mask no big deal in cleaning. I think the hose may have to be dumped but that's no biggie since hoses are only $12 on sale I think.
So who wants their stinky S8 cleaned?
Still want that manual though - just to be sure where we are looking for fastening devices.
